Hi Sasha,

i have (back)ported the patch to the older kernels mentioned below
where the original patch failed.

The patch appended to this mail applies to v4.14.121, v4.9.178, v4.4.180 and v3.18.140.
Some changes within the xhci driver prevented git from finding the correct position.

Hope this helps :-)

Best regards
Carsten
