Hi Thanos, I just went through this. Have a look at this wiki page:
https://github.com/ytai/ioio/wiki/Devices-With-USB-OTG-Host-Mode-Support Unless your phone has a micro-A connector (the tiny, rectangular one so you can plug the red cable that came with the IOIO into your phone), which is likely doesn't, you're going to need one of these: http://www.adafruit.com/product/1099 Combine that with a standard USB charging cable, plugging the above adapter into your phone and the standard cable from that adapter to the IOIO and you are good to go. Make sure the switch on the IOIO is set to "auto" mode, not "host" mode. Regards, Mark.
