Could you test that? 3.14 is not out. Do you mean Greg's usb-next queue? https://git.kernel.org/cgit/linux/kernel/git/gregkh/usb.git/log/?h=usb-next A simple fix is to turn off CONFIG_USB_DEBUG. That's what causes the xHCI dynamic debugging to be enabled by default.

More patches concerning dynamic debugging are in the queue for 3.14 It looks like on your system it is by default switched on. You can switch it off at boot time in the kernel command line as documented in Documentation/dynamic-debug-howto.txt HTH Oliver -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

You have XHCI debugging on. This is most likely a side effect of teh switch to dynamic debugging in 3.12. But this should be discussed on linux-usb.
