Representative logs attached. Occasionally, I would see a few more of the
"Element != First TD" printouts, but that was hard to reproduce.
I am assuming that something still isn't going right, since without your
debug patch, uhci-hcd still does some printks, and usbtest reports errors.
However, the final result code from testusb is zero. Is this normal?
