Something is going on, make sure to test this properly and fix "missed ISOC" once and for all. I will wait for testcases which show how to reproduce the problem and after applying this patch fixes it. Also, make sure to let me know how you tested it, which gadget drivers have you used ? I would like to have g_zero, g_audio and g_webcam tested to make sure different use cases are exercised. cheers -- balbi
