Ytai,

I have been trying more upgrades but no luck at all. I also take this 
opportunity to ask you the following:
I have been reading the IOIO-OTG Power Supply page 
(https://github.com/ytai/ioio/wiki/Power-Supply-OTG) but nothing is said 
about what I am going to ask.
Is it possible to power external hardware through 3.3V output when the IOIO 
is being powered through USB (smartphone only)? If so, how much power does 
it draw? "400mA for any external 3.3V peripherals"? I could test it but it 
safer to ask you first...
