I have tested this with version 1.0.12.Okay, I see that there has been some usb 3.0 changes in 1.0.13 and 1.0.14 and I am going to test again. > What makes you think this is related to xhci-hcd in any way?

The most notable change is that I now have USB 3.0 and that xhci_hcd doesn't appear to be too stable and is easy to blame. Unplug/Wait/Plug allows me to scan another page. Sometimes this leads to an oops in xhcd-hci (but the oops scrolls out of the console too fast and the system hardlocks and I don't have netconsole running). -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
