I would suggest try using usb2 port if the PC has one or unloading the

worked well there.
Unfortunately, trying different USB ports does not make any difference, as
all my external USB ports belong to the same controller. Would like to try
your other suggestion, unloading xhci_hcd and let the system fall back to
ehci_hcd. How do I do that? I tried blacklisting xhci_hcd, following the
instructions in the Debian Kernel Manual Chapter 6. When I rebooted,
xhci_hcd loaded anyhow.
