I downloaded the sources for the 3.19.0-43-generic kernel (Ubuntu 14.04.3).
Then I applied this patch:
*http://linux-kernel.2935.n7.nabble.com/TESTPATCH-v2-xhci-fix-usb2-resume-timing-and-races-td1250796.html
<http://linux-kernel.2935.n7.nabble.com/TESTPATCH-v2-xhci-fix-usb2-resume-timing-and-races-td1250796.html>*

I haven't experienced any issues so far with the new patched kernel.

Any idea when this patch will hit the official Ubuntu 14.04.3 kernel?
