Comment # 18 on bug 976813 from Johannes Meixner

Regarding comment#16 about using differnt USB kernel drivers:

I am neither a USB expert nor a kernel expert but according to
https://bugzilla.opensuse.org/show_bug.cgi?id=920067#c23
it seems in general it is not possible to use other USB
kernel drivers than those that are automatically used.

As far as I know nowadays USB3 capable hardware in the computer
is different compared to traditional USB2 hardware in the computer
so that for USB3 only xhci_hcd works but xhci_hcd does not work
for traditional USB2.

Note that I am talking about the USB3 chips versus USB2 chips
in the computer i.e. the hardware where the USB kernel drivers
are used for.

One can nevertheless connect a USB2 device to a USB3 connector.
Then the USB3 chips in the computer (with the xhci_hcd kernel driver)
are used for a USB2 device that is connected to a USB3 port,
