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 -- nvpublic
