My device has three interface: adb, usb mass storage and general serial. when I connect cable, the usb mass storage setup fail, and pc will reset usb bus sometimes, below is the infomation from usbmon: >From log, I can see after PC send the command cca5f000 4015670100 S Bo:1:091:2 -115 31 = 55534243 0c000000 00100000 80000a28 00000000 00000008 00000000 000000 the callback return -71(protocol error), what's wrong in this case? and I see in the device it enqueue the request of this, but didn't wait the request complete and receive the bus reset. But if the device build with two interface(adb+mass storage) or only one, it is always OK! could someone give me some advice on where I should check? f70ae400 4010276390 C Ii:1:001:1 0:2048 2 = 0400
