I want to develop on an unrooted android tablet that has both an OTG and Host USB. The Android Version is 2.3.0 so there are no Java api's to write directly to the USB host. The android device has to be attached to a computer using the OTG port so I need to connect the android host port to hardware I am designing (FTDI V2 in USB device mode). It seems the only way to communicate is using the adb to send commands from the Android tablet host port to my hardware slave port. My question is, is it possible to use the adb to communicate over the Android tablet host port, or will the adb only work on the Android tablets OTG USB port?
Any assistance appreciated....
