Hi, Thanx for ur suggestions and time . As suggested by you ( debugged the code that didn't shut down the USB streaming properly ) , i am finding that at USB disconnect , even the functions usb_audio_disconnect() && snd_usb_audio_disconnect() are not at all getting called . i need to check the shut down process of USB streaming to find out the reason . if some more pointers to code areas can be shared , it will be nice .
