maybe one of the reasons is that you use ep's queue without holding
any usbcore's locks in sl811 hcd...
BTW, I noticed something strange in "hcd_endpoint_disable". If I well
understand this function parse the ep's queue and free each of them by
(a) calling hcd->urb_dequeue method (b) kfreeing urb....Don't we need
to remove the urb from ep's queue somewhere before the queue is
rescaned from the start ?
