Hi,
I'm debugging a uasp driver under xhci kernel downloaded from:
git://git.kernel.org/pub/scm/linux/kernel/git/sarah/xhci.git
Now, the device can get the "INQUIRY" command. But during the data stage,
the uasp driver submit the urb by "usb_fill_bulk_urb" and "usb_submit_urb"
after evaluating, it return the valid return value. The problem is : callback
function " urb->complete( )" can't be recalled. The driver
enter "command_abort" after 20 seconds. I trace the prepare_transfer in xhci-
driver, the uasp did pass the valid stream_id to it. Is there any advice to
locate the problem of xhci-hcd?
Besides, when I plug the USB3.0 device before insmod uasp driver， the xhci-
hcd driver reponse the following info:
