Just thought I'd register and leave a quick note to say that it worked for me too! I bought the hub / fly lead OP linked to, changed the bios settings (PCI Mode and the option below it - can't remember what it says but it is literally directly below), set the cable to charge and all my USB devices worked a treat whilst the battery was being charged.

This has been a godsend as I was deliberating how much I'd be using the tablet without being able to connect devices and charge at the same time.

Cheers,
Paul

Yep, me too - can confirm it needs both BIOS options changing for it to work :)

Can anyone confirm how quickly this charges? I have the 8 inch and despite the tablet claiming that it is charging when plugged into a powered use hub it seems to be such a slow charge that it is still discharging all the time when in use.

I was hoping to be able to use this as a small desktop replacement when traveling with work connected to a monitor and keyboard etc for the day if needed but at the moment this wouldn't work

It does charge but remember the standard charger is only designed to charge the device and not power usb devices at the same time. When using the otg charging cable, all connected devices use the power from the adapter not the tablet. I have reservations if the included charger does in fact output the claimed 1.5 amps. Your best bet is to use a minimum of a 2 amp adapter and you will see dramatic improvement.

That was my feeling on the subject also... but a silly part of my was worried about using a differently rated wall adaptor :shock:

As long as the voltage is 5v youll be fine. if you had a 5 amp adapter it only means it can supply up to 5 amps. if the tablet only needs 1 amp then it will only take 1 amp. The wall adapter will not "push" more current providing the 5 volts is correct.
