Bug Description
I have been using a Novatel USB720 successfully for years on Ubuntu - after upgrading to 14.04 (then doing a complete clean install), I continue to get this in my dmesg:
[ 4220.244259] usb 2-2: new full-speed USB device number 12 using xhci_hcd

The device is obviously not working properly anymore.
