BDA device with stm32f4

Question asked by ismail fatih iltar on Dec 14, 2016

hi everyone. im trying to make communication between BDA device(for microsoft) and usb host stm32f4. My device is usb tv. and i wanna take signal from usb port and send this signal to ethernet. Terrestrial ip tv streaming i have linux driver for device (it uses v4L) i will take a source code for mcu from this linux driver. But i have no idea about comm. between mcu and bda device. In stm32f4 examples there are different kind of usb classes(etc HID,CDC, Audio) but which class should i choose for this device? or what class should i create for it ?  i cant find enough documents about that.  Thx
