Hello, I'm trying to connect stm32f4-discovery with Android phone supporting otg through USB virtual port. The microcontroller should work as device and smart phone will be the host. I used CDC library on stm32f4 side and do I need driver for Android to communicate via USB? because when I connect stm32f4-discovery with phone I cann't send or receive any thing, moblie even doesn't feel that I have connected the kti with it!
Thanks in advance
