USB, u gotta be Quick.

So ya'll know usbA 3.0 has extra pins in the back.  Got a complaint from hughmann today that his devices were sometimes usb 3.0 speeds and sometimes usb 2.0 speeds.

Turns out, he was inserting the usb too slowly, so when the detection comes, sometimes it locks to 2.0, because the extra pins didn't touch in time.

He were just sliding them in there super slow, visually guessing 1-1.5mm/second.

He claims he don' want to break his port.

Interesting.

If a device has a separate cable, the solution is simple though: Connect he USB A side first.

This can also happen if not pushed in far enough and on some they are simply too far back, I have one thumbdrive that is super fickle about what ports it works on at full speed.
I've had enough troubles with it that at this point I feel it's just not really a great connector in general.

By the way, he's not wrong about damaging it, in the port on my Macbook Air, the fingers had been completely smushed in, luckily it was on the one daughter board in the system and not the logicboard. I've seen several others this way.

Ans as much as I like the type C connector, the industry has made it a complete and utter f'ing joke. I cut open a type C extension cable to make a short dongle for my Filco, both ends are type C and it has Type C power wiring, it's even reversible, but it's only USB 2.0 in terms of data connection. Honestly, it worked perfect for what I needed since it only had one extra power and ground compared to 2.0 but just shows not everything is what these companies claim them to be.

I thought there were different type C cables, ones with more and less wires, no ?

Cuz it's 24 pin, you don't need all 24 of course for all operations.

How could they pin out to 4x pcie speeds without more than 4 pin ?

[Leslieann]

There are different types but sellers are not saying what they are selling.
The Type C extension cable I bought was more or less a high power 2.0 cable with type C ends, it can do high power transfer but not high data transfer. One I almost bought wasn't reversible if you connected it to a type A to type C adapter because they never connected the backside for it.

There's some seriously shady companies making these things.

I'm not sure most people want a full speed extension cable though. Because they're really thick.

The usbc cable for highspeed laptop docks are almost a centimeter in diameter.

The Type-C spec is quite complex, so I can understand how people can make mistakes or cut corners.
It lists eight types of compliant C-to-C cables, including two types of USB 2.0 signals over Type C. But it is not easy to find the info about what makes them different, and I don't want to be bothered needlessly.

When it comes to A-to-C, there are also non-standard cables for charging cell phones and whatnot.
Charging cables for the VOOC chargers, used by Oppo, OnePlus and a couple more, even has a proprietary non-standard pin in the type-A plug/sockets!

The spec is purposely left open to interpretation.
The standards group has also been known to ease existing regs if you complain enough.

They should just add a line to the rules "close enough is good enough" or "don't worry, we'll approve it".

I have several and it doesn't excuse them making false claims.

Its inevitable that you will have to plug it in the wrong slot a couple of times before it starts working

[Kavik]

That's rather interesting. I never would have guessed that could happen, but I suppose it makes sense.
