After some research, I've found many complaints on xhci_hcd driver with
Linux kernel 5.13.x, some versions seem to work, some not, some with
workarounds. So I'd say, in general USB 3.0 support seems to be broken
currently (depending on device and kernel version).
Anything I can do to get USB 3.
Hello,
the bluetooth problem seems to be caused by USB driver problems. This is
the output of "lsusb -t":
$ lsusb -t
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/14p, 480M
