Bug#698531: xhci_hcd fails to set up USB devices on NEC uPD720200



Package: src:linux
Version: 3.2.35-2
Severity: important

Splitting this from #614801, as I don't believe it's the same bug.

leads to this in dmesg:

and USB devices are not detected.


Please tell me if you need more info or if I should test something!


Thanks,
