These problems could very well be caused by running at SuperSpeed
(USB-3) instead of high speed (USB-2).

Yes, it's running at SuperSpeed, on a Kabylake laptop.

It does not have this issue on a Broadwell laptop, also running at SuperSpeed.

Then I must join Oliver, being very surprised by where in the stack you
attempt to fix the issue.  What you write above indicates a problem in
pci bridge or usb host controller, doesn't it?
