Mathias: Your patch description says this: > The endpoint might already processesed some TRBs on the endpiont ring > before we soft reset the endpoint. > Make sure we set the dequeue pointer to where we were befere soft reset However, if a driver tries to issue an endpoint reset while there are still some URBs queued, it is a bug. Host controller drivers shouldn't have to worry about this -- xhci_endpoint_reset() should simply return an error if the endpoint ring isn't empty. I suppose we should check for this in the USB core. I'll write a patch and CC: you.
