I put printk in fsg_main_thread. After insmod g_file_storage, the fsg_main_thread goes to fsg->running. Then it sleeps. When ep1 receives data, get_next_command() is not called, so start_transfer() is not called. The fsg_main_thread is sleeping in sleep_thread(). How to make it wake up? is there anything udc driver has to do to wake up fsg_main_thread? thanks, victor -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
