Sorry for the delay. Today I set up a local board to reproduce this on
and was able to recreate the same problem. The Tegra xhci driver does
not power off during suspend and simply calls xhci_suspend(). I also
checked vbus to see if it was turning off but it is not. Furthermore I
don't see a new USB device detected after the error and so I don't see
any evidence that it ever disconnects.

Cheers
Jon
