Title: Making your own custom USB cables
Post by: nubbinator on Tue, 18 June 2013, 22:47:47
Since I haven't seen a thorough guide yet for making your own USB cables, I decided to make one.  I realize that this doesn't make good business sense since I do sell some of my own cables, but I also like to make things easily accessible to people.  A lot of this community and the computer building community was built on DIYers and their public experiments, so I feel it's only right to help people have easier access to guides that can help them actualize some of their visions. 

I know this is a topic that's a little scary for some people and it does take time and practice to get right, but I figured making a guide might make it a little less scary.  I know that when I started making my own sleeved USB cables (http://geekhack.org/index.php?topic=43891.0) (and all the cables to date (http://imgur.com/a/RDsbd)), it took some work to find some good documentation for the tiered connector on the USB Mini B and for the process of making your own cables.  While there are some guides that are great for sleeving, they don't have a ton of documentation on the connectors and housings.

And a disclaimer, to me this is a fun project to do and gives you a lot of latitude for sleeving, but, depending on how many connectors you get and where you source them from, you might end up spending more than what several of the artisans out there charge for a single cable.  I don't want to discourage anyone from it since it's a fun project and definitely teaches you some things, just expect it to be a little costlier than you'd expect.

Tools you'll need:

- Soldering iron

- Tweezers.  I use  these since they're cheap and decent (http://www.amazon.com/Amico-Length-Anti-static-Straight-Tweezers/dp/B00BG8WW2Y/ref=sr_1_12?ie=UTF8&qid=1371612591&sr=8-12&keywords=esd+tweezers).  You can use any old tweezers.  Finer needle nose pliers might work in a pinch.

Recommended tools:

- Helping hand (http://www.amazon.com/SE-MZ101B-Helping-Hands-Magnifying/dp/B000RB38X8/ref=sr_1_2?ie=UTF8&qid=1371612700&sr=8-2&keywords=helping+hand).  You don't need anything big or fancy, any cheap one will help.

- Painter's tape (http://www.amazon.com/ScotchBlue-Painters-Multi-Surface-70-Inch-60-Yard/dp/B00004Z4BB/ref=sr_1_2?ie=UTF8&qid=1371612754&sr=8-2&keywords=painter%27s+tape).  I use this because it doesn't leave a residue.

- Wire strippers.  I use these fairly cheap strippers (http://www.amazon.com/dp/B006962E7G/ref=biss_dp_t_asn) and they're fantastic.  You can also use a pocket knife, Exacto knife, or razor blade.

- Razor blade for removing the plastic shell from the USB cable and cutting the shielding.

- Adjustable temp soldering iron. This can be something nice like a Hakko 888D or something cheap and dirty like my Weller and home made setup (http://i.imgur.com/2ihxLUO.jpg).

Parts you'll need

- USB Cables

- USB connectors and housings of your choice (USB A, USB B, USB Mini A, USB Mini B, Micro USB).  Keep in mind that there are different permutations of connectors, so the number of pads may be different on some and the placement of the pads may be different.  If that's the case, you'll need to try and disassemble the connector to find out what goes where.

- If for a Filco, Molex housing (http://www.mouser.com/ProductDetail/Molex/87369-0500/?qs=%2fha2pyFaduh22y0S%252bKc0pv0eO4C6r4h6Vk9YfDEsxcvfK3qo5o67Hg%3d%3d).  You'll need a crimper and the appropriate crimps to do this.

- 3:1 heatshrink

- Sleeving (paracord, MDPC-X, etc).  Be careful with paracord as the sizing is inconsistent and the stuff you buy might be too small to fit over the cable.

Making your cables:

USB A Connector

USB A Pinout
(http://i.imgur.com/eVqYEnSh.jpg)
Since USB uses a universal color code, it's pretty easy to make your own cables with an assortment of different USB connectors.  This is a handy little pinout for your common USB A connector.

When it comes time to solder, just match the tinned wires to the right pad and reflow your solder.  If you didn't get enough solder from tinning, it's easy to add a little more. 

I recommend a using some helping hands and tweezers for this task.  I also find it useful to tape the connector down to a flat surface while soldering the wires in place.

Once your wires are soldered properly, I like to add a little hot glue as an insulator and to add a little more strength to the solder joint.


(http://i.imgur.com/T7g27Ebh.jpg)
If you get a two part housing like I use, these two little pegs/legs serve as guides for the housing so you get your connector seated perfectly every time.



(http://i.imgur.com/iTtUwoyh.jpg)
This the snap together two part housing I use.  Slip on housings are more common.  If you get some of those, ignore this part.




(http://i.imgur.com/t5USTqvh.jpg)
This is the little groove you slide the pegs/legs from the connector into.  There's a little room for wiggle, so don't be worried that the connector isn't gripped tight.


When you slide the connector in, it should end up looking like this:

USB Mini B Connector

USB Mini B Connector Pinout:
(http://i.imgur.com/RqPxH1ih.jpg)

Since USB uses a universal color code, it's pretty easy to make your own cables with an assortment of different USB connectors.  This is a handy little pinout for your common USB A connector.

When it comes time to solder, just match the tinned wires to the right pad and reflow your solder.   Take your time and make sure your temps are right.  If you get it too hot, you can melt the pads out of the housing. 

I recommend having a helping hands, tweezers, and some sort of magnifying glass on hand for this. I also find it useful to tape the connector down to a flat surface while soldering the wires in place.

Once your wires are soldered properly, I like to add a little hot glue as an insulator and to add a little more strength to the solder joint.

This the snap together two part housing I use:
(http://i.imgur.com/yOlwfGyh.jpg)



(http://i.imgur.com/jxtVr5sh.jpg)
This is the little groove you slide the lip from the connector into.  If it's not seated properly, the housing won't close.


(http://i.imgur.com/wp59dhMh.jpg)
When you slide the connector in, it should end up looking like this.


USB Wires

(http://i.imgur.com/YVRrcBo.jpg)
Not my picture, but this is your standard USB cable.  You will need to strip the wires and tin them.

(http://i.imgur.com/MyQ9gGi.jpg)
In case you don't know what tinning is, tinning is the process of adding solder to your stranded wire that you'll be soldering.  You can either hold the iron at the tip or on the backside of the wire and when it gets hot enough, the solder will flow into it.


More pics to be added later.

The cable guide is awesome but the one thing that really helped me is the last picture. I never learned tinning when I was learning to solder. I have one question though, how to you strip the very small usb wires? I just used a crappy tip on my soldering iron and melted the plastic sleeve off. Thanks so much for posting this  :)

Get some wire strippers. They will make everything so, so much easier.

Thanks, but unless I get a benefactor or sugar mama I need a real job.  Without a real job,  I won't have the money to keep doing experiments and guides.  And don't worry, once I do get a job, I'll still set aside time to do this stuff. It's a fun little hobby and way of unwinding and, like I said, I like to grow the knowledge base with good keyboard science.  Even when I was in grad school and working 20-30 hours a week, I still found time to make guides, put together a database, and organize contests for /r/buildapc on Reddit.

I use these cheap wire strippers (http://www.amazon.com/dp/B006962E7G/ref=biss_dp_t_asn).  It's not too expensive of a tool and works great.  Most USB wires are in the 24-28AWG range, but some are as big as 20AWG.

You may or may not save money on the cables making it yourself once you factor in shipping and component prices. It really comes down to how many you decide to make and the prices you can find.

For example, here's a price run down with current prices:

- $1.59 for the USB A connector and housing I use (http://www.ebay.com/itm/USB-2-0-Type-A-Plug-4-pin-Male-Adapter-Connector-with-Plastic-Shell-Good-DIY-New-/151049629123?pt=LH_DefaultDomain_2&hash=item232b426dc3)

- $5 for the USB Mini B connectors I use (http://www.ebay.com/itm/10pcs-Complete-Set-Male-USB-Mini-B-Type-Connector-Mount-Socket-/251146391206?pt=LH_DefaultDomain_0&hash=item3a797dcea6).  You might find a single cheaper elsewhere, but it's not common.

- $5-6 for a USB cable if you don't have a donor cable you can use (that includes the cheap ones from Monoprice since they charge $5-6 for shipping)

- ~$1.40-1.75 + Shipping for 3:1 heatshrink (http://www.cableorganizer.com/heat-shrink/heat-shrink3.htm)

- $4.80 + shipping for 6' of sleeving of the sleeving I use.  In all reality, this will be closer to $5.60+ shipping since you'll need a little over 6' for a 6' cable.  Even cheap paracord will cost you around this much since you can't find it in under 25' lengths.

- Total - $17.79, not including shipping, probably closer to $25 with shipping.

Like I said, I don't want to discourage people from doing it since it's a good learning experience and it does give you a ton of room to experiment and do what you want, but don't expect it to be cheaper, especially if you have to buy tools to do it in addition to supplies.  It only really becomes cheaper if you plan on making several of them.

Hadn't thought of that, but it that's a great recommendation.  I just keep that tab in case, for some odd reason, someone wants to turn it into a host.

And that certainly does help and makes it easier to double check that you didn't accidentally bridge your data and ground wire.

That 5th cable could be a shield cable in which case it would connect to the housing if you're placing the connector in a metal housing.  If it's for a Filco cable, it's likely the shield/ground cable. If it's for a host USB cable, it could be a second ground that you would solder onto the one unlabeled pin on the 5 pin USB Mini B.

Honestly, without seeing what's on the other end of the cable and what's soldered where, I couldn't tell you for certain and wouldn't want to chance telling you wrong.
Title: Re: Making your own custom USB cables
Post by: CPTBadAss on Sat, 22 June 2013, 09:31:29
I'll try and take apart the other end but I think the cable was originally a mini USB to USB cable so there's no snap fit housing. I have to rip apart a bunch of rubber. Let me see what I can do and post some pictures later.

Edit: The cable was mangled and I couldnt find the wires. The end was inpregnated with rubber and I destroyed it trying to open it up. So I don't have pictures to show...Guess I'll just risk it and see how it goes.

I just finished my first soldered cable (mini side).  Those pins are tiny!  Tough to do with the standard flat tip on my old Hakko Red 503. 

I used a white usb to 30 pin ipod cable as I wanted the Toxic yellow sleeve to be as bright as possible.  Over a black cable, the sleeving is significantly darker.

Before:

After:

Thanks again nubbinator for the excellent tutorial and the parts.

Post by: nubbinator on Fri, 28 June 2013, 00:31:51
Looks good.  I really like that color yellow.  And I'm glad my tutorial was nice and easy for you to follow.

Those pads definitely are tiny.  You do need a finer tip on your iron than a flat tip to do it easier.  I recently started flowing just a hair of solder onto the pads in addition to the tinned wires and it makes it a little easier.
Title: Re: Making your own custom USB cables
Post by: Badwrench on Fri, 28 June 2013, 00:34:37
That is exactly how I had to do it.  I would flow a tiny dot of solder on the corner of the flat tip, and touch that to the pad until it flowed on the pad.  That plus the tinned wires and I was good to go.

Got a quick question:

I have a cable with paracord sleeving but it is too small to get held by the mini usb housing. Is it ok to put some hot glue/super glue around the paracord and glue it to the housing after I soldered all the wires?
Also then the hole in the back is still to big and the cable (with sleeving) can wiggle around, is that bad for the cable?

thanks.
Title: Re: Making your own custom USB cables
Post by: nubbinator on Fri, 28 June 2013, 17:48:27
Yeah, hot glue is fine.  You can also do heatshrink around it.  Either is fine.

It should only pose an issue if it's getting wiggled a lot.  If you're worried about that and want to be sure it'll be ok, just squirt some hot glue onto the wires and where the wires connect to the USB connector, pop the connector into the housing, and squirt a little more hot glue in there.  The hot glue is a great insulator and will give it a little extra strength.

There appear to be some inconsistencies between these images. I believe White should be D- and Green should be D+ as in the first image. I am not sure how much it matters to switch the negative and positive data around though. Surely they don't switch depending on what USB type connector it is since they use the same colour. Fyi, your images are some of the first hits on Google for 'USB pinout' nubbinator.

Bumping this question again. Does the polarity of D+ and D- matter? The colours don't correspond to the same on the larger and smaller USB ports according to the images here, and neither does the pinout. Which is correct:
White = D- and Green = D+ as in the first image, or
White = D+ and Green = D- as in the other two images

Second question, in the second image, is the lower middle one green or D-?

Polarity matters (you must connect D+ to D+, and D- to D-), but wire color doesn't. White and green is one twisted pair in the cable, you must use them for D+/D-, but which is which doesn't matter.

On five pins connectors the middle pin is D+, which is usually green:

You could have flipped the data lines on one end, it could be soldered to the wrong point, you may not have a good solder connection, you could have overheated the pad on one end and slipped the connector out of position in the housing, there are a bunch of possibilities.

Great guide, thanks!

Does this apply to USB 3.0 cables as well?

Also, are there after-market USB 3.0 internal connectors?  THOSE are the cables that are always the wrong length.

IMHO.   ;D

USB 3.0 has additional solder points inside from what I remember.  I've only really seen 3.0 A connectors, nothing else.  And some of those connectors/housings aren't that great.  Also, keep in mind that anything from China may not be completely as advertised.

USB 3.0 has 4 additional pins that are two very high speed differential pairs, like SATA (or PCI-express). Hand soldering these is at best challenging, if at all possible. You need to get the shielding and the impedance right, the wires length must match very precisely. But you don't need USB 3 for a keyboard (or any input device for that matter).

Great guide, thanks!

Does this apply to USB 3.0 cables as well?

USB 3.0 has 4 additional pins that are two very high speed differential pairs, like SATA (or PCI-express). Hand soldering these is at best challenging, if at all possible. You need to get the shielding and the impedance right, the wires length must match very precisely. But you don't need USB 3 for a keyboard (or any input device for that matter).

Thanks for the info.

I was asking because I would very much like to be able to shorten the long front-panel USB 3.0 cables that come with cases and bay devices.  You know, those horrible thick things with the molded ends that cannot be bent or made to lie neatly?  I would love to be able to mod those.

Finding a mini usb is  hard in our area and the market is flooded with micro usb. Thanks for this guide nubbinator, I was able to convert micro usb to mini usb. For a $2 micro usb, can't complain.  :))

Hey,

I don't mean to derail this thread, if the mods think this post should be placed elsewhere, please let me know.

I've made a few USB to Lightning cables thanks to this thread!  Would anyone happen to know why they randomly stopped charging my iPhone?  I don't believe it's a physical cable issue, but potentially related to "Unauthorized Cables" as often prompted by the iPhone.

Any advice or recommendations you might have would be greatly appreciated.  Thanks!

Mitch

Did you update to 7.1 or higher on iOS?  Apple started cracking down big time on non-MFi lightning cables on that first big update to iOS 7.  Secondly, I'm assuming they do say "this device not made for iphone"?

The metal tube is nice because you can heat the tube and get mite even heat across the cable.  Just my preference.

I am running iOS 8.1 (jailbroken) on my iPhone 6 and iOS 8.1.2 on my iPad mini Retina.

Now that you mention it though, it stopped giving me the prompt "This cable or accessory is not certified and may not work reliably"... Maybe the physical cable just failed, broken strand or solder potentially.

At any rate, does you know, is the part that indicates the cable is certified (MFi) within the Lightning connector itself?  The reason I ask, as much as I'd hate to do this, if I were to chop Apple OEM cables keep the OEM Lightning connector but replace the USB A Male end, I might bypass this issue?

Thanks again!

Yeah, the MFi signature thing is programmed into a chip in the lightning end itself.  Easiest way to do is get either the monoprice or gear beast cables and mod from there.

This is a great thread and I have learned a lot here. Thank you guys  :thumb:  I have acquired all the materials to make a few cables but I've noticed that different cables have various charge speeds (I think due to various size AWG wires) and the donor cables I purchased for this project aren't very good.

Are there any particularly good but still affordable donor usb cables? (I will be working with paracord)
Is usb shielded cat5 cable?   Does anyone know of cable that can be purchased by the foot but will also fit inside paracord?

What cables to you recommend getting that are thin enough to fit through paracord? The only one's that I've found that worked were pretty short (3 to 5) feet. Do you guys know of any longer cables that I could harvest?

USB is not l like shielded cat5cable at all I don't recommend using non shielded USB but y you can use one twisted pair for data and the rest for power and ground.  Good USB cable has thicker wire for power and ground. Remember best practice I usually to connect shield on one side but connecting on both is usually ok too. I connect both for metal case kbs and then make sure the case connects to shield.

The cable I use is ultraminiature double shielded quadmic cable but its a real pain to work with so I don't recommend it at all. If you search you can get USB cable bt the foot. Should be under $.30 or maybe a little more for really good stuff. Nowadays I harvest cherry kbs for parts and I always save the cable as cherry uses top spec cable but I don't think it'll work under paracord.

And for coiled I harvest cherry ps/2cables.

Sorry for typo on phone

Sorry if these have already been answered elsewhere I read the whole thread without seeing them.


I am not sure about heat shrink because I used hot glue and housings.
550 paracord works with thin usb cables.

You shouldn't have too much trouble buying cable to make usb cables... Definitely don't need to go to alibaba. If you google something like 4 core 28 awg or 24 awg (I use 24 awg) cable you should have plenty of results. You also don't really need shielded cable unless you have a noticeable amount of EMI that affects your equipment, don't need that drain wire inside as well.

If you need to buy all the equipment then the initial cost will be high, but the cost per cable will be low when you divide the cost of the cable parts.

Well I have a soldering station, I have a hot air blaster... I ordered some shrink cable and plugs but I really can't find by the meter 4 core cables with 26/28awg.
It's probably because I have to search on polish websites and I don't speak polish... so it kinda complicates it.

I already tried all kinds of combinations of 4 core 4 wire awg etc. and didn't find anything really. very annoying.

I'm also a little confused about the paracord. do people generally just buy a few meters of paracord and then sleeve it themselves or would one just buy already sleeved cable?

And yes, you just buy the paracord, take out the 7 strands inside and sleeve it over the cable.

Sorry it took me so long to report back but yes it is really nice cable and very nicely packaged. 28 gauge seems to be the absolute perfect gauge for paracord sleeving as well so that worked out purely on luck.

I can take some pics of the cable with the end stripped so you can see the quality if you want.

And yes, you just buy the paracord, take out the 7 strands inside and sleeve it over the cable.

Moved from SoCal to Poland... things are complicated here... I can literally not find any place that just sells cable and ali gives me 1000m MOQ...

Can you not order from l-com? If not I will be buying another 100' of 28ga and 100' of 24ga next month. I could reship some to you next month if you're still unable to get just straight USB cable in Poland.

One thing that I have been meaning to ask everyone, what size heatshrink do you use? I have quite a bit of 3/8" 3:1 heatshrink (25' of black, purple, blue, orange, and clear) which seems to be almost the perfect size, any bigger and when it is shrunk it wouldn't fit the cable and any smaller and it wouldn't fit the USB-A connector. The only problem is that it has to be stretched a tiny amount to fit over the USB-A end. Once it is on there the sharp edges of the connector make the heatshrink look a little thin to me on the colored heatshrink, the black and clear are thicker and the sharp edges don't look bad on them but the colored shrink looks a little rough to me.

I am not sure if that is because I bought the heatshrink from CableOrganizer.com (http://www.cableorganizer.com/heat-shrink/heat-shrink3.htm) and their colored shrink is just thinner but I haven't been able to find that range of colors from any other place. I know MDPC-X has some of the colors but they definitely don't have them all (they're missing purple, orange, and clear) and since their heatshrink is so much more expensive I don't want to buy it without knowing it is thicker than the CableOrganizer shrink. Even if I do go with MDPC-X in the future I will still be missing some colors which I really want to go without (orange is my favorite color).


Also, what does everyone use to clamp the metal shield for the USB connectors to the cable? Right now I am using a pair of needle-nosed pliers but I feel like there is a tool, like there is for the modular power supply cable pins, that I could buy to make the clamp more uniform without having to spend so much time on it but I haven't been able to find it yet.

Sorry for the necro, but if anyone is still wondering about where to get unterminated cable from: I couldn't find any supplies either, so I am using this from Aliexpress as a substitute: https://www.aliexpress.com/item/20M-15M-10M-5M-USB2-0-Male-to-Female-Active-Repeater-Extension-Extender-Cable-Cord-M/32667153074.html
It's a 20m usb 2.0 extension cable that you can just use to cut off as much as you need. I didn't buy this one exactly, I bought one from eBay.co.uk but I'm pretty sure it's the same stuff, and it's pretty substantial at around 5-6mm in diameter (don't have a set of precision measure tools).

No need to import from abroad.

I'm in UK as well and I get my cables from CPC and Farnell. You need to search for something like 4 core 24 or 28 awg cable (I use 24awg). You can get them for about £10 for a reel of 100m of unshielded cable, which are perfectly fine for making USB cables.

The product code for the cable I use is CB11474 on CPC. This is unshielded. I only use these for non-coiled cables, they do not coil well at all. For coiled cables I use a different cable but it's 4x the price.

Saw this thread a month or so ago when I got into mechs and immediately ordered everything i needed to make cables, finally got everything in yesterday and have made 3 so far, I love it! I have a few questions... (based in the U.S., just fyi for order questions, and yes I searched google but its hard to find solid recommendations)

1. Anyone know where to get lightning adapters? I would love to make some charging cables for friends/family but can't seem to find them anywhere.

2. What spots do you like to order MDXPC sleeving from?

3. Another sleeving questions. saw a cool cable consisting of Braided OFC USB cable that was shown on this thread, where do any of you recommend ordering that from?

I thought that to meet usb specification the wire had to be shielded and have twisted data pairs? How many cables have you used this for and has it held up well to being used as a data/power cable?
I had saw this stuff before buying the extension cord, but I was dubious as it wasn't up to the usb specification and I didn't want to be stuck with 100m of the stuff if it wasn't good. Would be a really good option if everything is good with it though, as you get 5x the length for the same price (and it's thin enough to wrap in 550 paracord too, whereas the stuff I posted isn't)

If you read up USB cable specs, there are many sources that say shielded is not absolute necessary. For environments where interference like EMI could be a problem and actually affect the data on each end of the cable then shielded cables are needed. Twisted pairs are for cancelling out EMI as well. Unless you live in an area where EMI is actually a problem then yeah, use shielded. But really how many people's households are actually affected by this lol.

I'm half way through my second 100m reel and none of the ones I've sold has come back. I won't name who but a reputable cable seller here in U.K. also uses non shielded cables for non coiled cables. I only use shielded for coiled cables because it holds coil much better.

So really, shielded cables are not really necessary. Some people don't go anywhere near unshielded cables but that's just in their heads if you ask me haha. That reel on CPC is fine for straight cables.

You can get them off aliexpress. I stayed away from them because I don't trust the quality of them. iPhones and iPads are not cheap devices. Imagine if them connectors did some kind of damage. Some people say lightning cables are flimsy and break all the time but I always say it's user error. I've never broken a cable from my iPhone 3G, 4, 5, 6 and now 7. If you take apart a lightning cable they are actually very well put together, they're not cheap but I rather pay the extra for a genuine lightning cable.

Sleeving is either paracord if you are into that, or sleeving from MDPC-X (very high quality) which is a bit stiffer and more plastic-like.

But I want to ask something else. How do I choose thickness?
I mean, i want to use a specific sleeve that only have 1/4" available. I guess that's about 22AWG. Do I use a cable a little thiner (like 23 AWG) or with the same thickness?

Same question for the heatshrink.

I use 3mm techflex, 24awg wire. 22awg will work but you'll find it more difficult to solder the wire to the connectors, especially mini/micro usb connectors.

Those ones don't seem to be easy to get hold of. I had trouble sourcing large quantities of them in the UK. If the connector size isn't an issue, you'd be better off using the larger plastic cased ones and they're available everywhere.

If you manage to find some let me know!

The paracord majority of people use (including myself) for sleeving cables are commonly known as 550 type III paracord. These should be listed as 4mm diameter.

The cable in the digikey link is 3.81mm outer diamter, it is labed as 'Jacket Diameter'.

what are you using for the cable itself do you have a way of getting unterminated usb cabling?
o and what size sleeving should i get?

I get mine from Digikey (https://www.digikey.com/products/en?keywords=cn230b-50), but you can probably find it on eBay cheaper.

I use 550 paracord for sleeving.
are you using just regular 550 para-cord?
and I dont see the diameter of the cable it self on the digikey listing

The paracord majority of people use (including myself) for sleeving cables are commonly known as 550 type III paracord. These should be listed as 4mm diameter.

The cable in the digikey link is 3.81mm outer diamter, it is labed as 'Jacket Diameter'.

What do you use to make the coiled cables? I'm struggling to find a 4-core cable that is thin enough for paracord.

Strip the jacket off the cable and it'll fit in the Paracord just fine.

Have any of you dealt with these type of connectors? I cannot figure out how to keep the metal from sliding out of the housing without resorting to glue or something. Anyone have any ideas?

Here is a 100" spool I have found:

Does anyone know if this works for USB- C cables? sorry, I'm late to this thread.

Hello,
First time making a cable (USB A to C) and it doesn't work. When I connect the USB A in my PC and the C in my phone, it charge but I have an error message from Windows (does this type of cable only works with keyboard/mouse ? I haven't found anything and actually have not a custom keyboard).
I tried with several phones and ports on my PC, I resolder the cable twice and I don't know what it it.
Have someone an idee ? Have I done a mistake ?
Thanks in advance

Might be a bit late to the party, but this is the only place I could find the wiring for the mini B connector (the one with the kinked shape) http://i.imgur.com/RqPxH1ih.jpg
Unfortunately I think the diagram shown here has D+ and D- reversed. I was trying to make a custom USB cable to program an Arduino nano board and couldn't get it to work until I swapped the D- and D+ connections.
I believe D- should be on the top row of 2 pins, and D+ on the bottom row with 3 pins. So the bottom row should be GND,D+,Vcc.  This also seems more consistent with the micro plug.

I just (two days ago) used this pinout diagram for my mini connector. Worked like a charm. Looks like the pinout you're looking at did swap D+/-

Thanks for confirming rubik, that's a nice clear diagram. Forgot to thank nubbinator for starting this useful topic. Can now make progress with my geeky project :) http://www.philizound.co.uk/plasma/plasma.html
