Title: HHKB Pro2 USB Hub
Post by: boost on Fri, 24 May 2013, 09:53:22
Can the hub on the hhkb supply enough juice to read flash drive? When I plug my flash drive in I get "Not enough power for the device"...

USB 3.0 requires quite a bit more power, thus why the drive won't be read.

They only provide 100mv I think, that is barely enough to keep a modern smartphone ticking over, never mind charging it a resonable rate. It is fine for a mouse, but nowhere enough for a USB Drive or a card reader.

Perhaps, but it'd require a mod. You'd need to somehow have external power for the USB.

Nope, USB can only provide 500MV anywho. The hub is only good for mice really...  :(

I had only one usb 2.0 flash drive work on the HHKB hub, a Corsair Flash Voyager others not enough power most mice wont work and draw more than its 100ma. rating. The hub on the HHKB Pro 2 is pretty much a useless feature.

I use my mouse with it. That's what it's good for. Especially when using it on laptops with limited USB ports.

The mice I use a Steelseries Sensi or a Razer Taipan wont work, not enough power. I have not tried others, I have to plug my mouse in my laptop to use it.

Probably good enough for a wireless mouse's USB wireless receiver.

That's odd. I fail to see what makes the Sensei take more power than the Logitech G9X (which is what I am using on my HHKB USB port)

The MacBookPro system report on usb shows the Sensei requires 200mA the HHKB's is only100mA.

Well this sucks. This was literally one of the best things I was looking forward to about a HHKB... Now I don't know what to do.

My advise is not to share high power consumption via the spare port of keyboard.

For laptop, I will use usb hub to share:

For desktop, I will use powered-usb-hub to share:

There is very few devices that work with HHKB hub. Only things I could get to work were mice and headphones (crappy logitech ones, nothing fancy).
