Hello Guillaume, I believe that when connected to Android the IOIO-OTG works as USB host. When connected to PC the IOIO-OTG works as a USB peripheral node (aka USB device).
>I'm using a usb-a connector on my board as I have no need for host mode You are probably mixing things as the USB-A connector is for USB host and USB-B is for device. As you were able to connect IOIO to PC in bootloader mode then I think that you actually have USB-B connector on your board (or mini-B, or micro-B). You should not skip the host mode if you want to have communication with Android.
