[time-nuts] Flash!!! FA2 works on Arduino Tablets !!!

[Didier Juges]

The tablet will not accept charging current when in the OTG mode, which is
required to make the tablet a master (USB is asymmetrical system, there is
always a master and a slave). It is not a function of the type of hub
plugged into it.
When you plug the tablet into a PC, the PC is the master and the tablet
will charge from the PC.
When you plug an accessory into the tablet, it becomes the master and it
delivers power to whatever is connected to it.
