I think the major question is that the driver doesn't know whether it is necessary to stop submitting bulk transfer or not. There are two situations with the same error code. One needs to resubmit the bulk transfer. The other needs to stop the transfer. The original idea is that the disconnect event would stop submitting transfer for the second situation. However, for this case, the disconnect event comes very late, so the submission couldn't be stopped in time. The best solution is the driver could get another error code which indicates the device is disappear for the second situation. Then, I don't need to do delayed resubmission. Best Regards, Hayes
