Comment 215 for bug 1667750

tested another USB controller (at this time 3.1) and the results are even worse than on USB 3.0:
USB controller: Advanced Micro Devices, Inc. [AMD] X370 Series Chipset USB 3.1 xHCI Controller (rev 02)
and
TENDA W311U+
ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter
This device is one of the few that work on an USB 3.0 controller
Advanced Micro Devices, Inc. [AMD] Family 17h (Models 00h-0fh)

but it failed epically on USB 3.1:

I really hope it will be fixed until we reach next LTS-KERNEL.
