703c with keyboard, can charge too?

19 January 2013, 15:35

I'm a total tablet (and sorta android) newby.

We got this 703c a few months ago; then a keyboard from amazon. Keyboard works awesomly; but can I somehow use the keyboard and charge it at the same time using a usb hub?

Taking a guess here...

I *think* that the pin that enables OTG also toggles the USB to OUTPUT power. I also *think* this could be "fixed" with some tweaking in the kernel but you would lose power OUTPUT in OTG mode altogether. You would then need a power injecting Y adapter between the OTG port and your slave devices.
