At this point everything was working.  A 4096-byte read just completed
normally.

This shows a 28-KB read that failed after the first 4 KB had been 
transferred.  No further data was received and the transfer was aborted 
after about 30 seconds.

This shows the start of a reset.  Apparently the reset did not finish 
normally.

Obviously there is some sort of communications problem.  Either the
device stopped transferring data or else the xHCI host controller
stopped receiving it.  From the usbmon trace, there's no way to tell 
which.  However, if the device works okay with an EHCI host 
controller or on another computer, that would indicate the problem is 
in the xHCI controller.

Maybe Mathias can offer some advice.

[PATCH] usb: dwc3: ep0: Fix the possible missed request for handling delay STATUS phase

2017-01-14 Thread Baolin Wang

When handing the SETUP packet by composite_setup(), we will release the
dwc->lock. If we get the 'USB_GADGET_DELAYED_STATUS' result from setup
function, which means we need to delay handling the STATUS phase.

But during the lock release period, maybe the request for handling delay
STATUS phase has been queued into list before we set 'dwc->delayed_status'
flag or entering 'EP0_STATUS_PHASE' phase, then we will miss the chance
to handle the STATUS phase. Thus we should check if the request for delay
STATUS phase has been enqueued when entering 'EP0_STATUS_PHASE' phase in
dwc3_ep0_xfernotready(), if so, we should handle it.
