    Also, these devices used to work about a year ago (same machine, earlier
    kernel) and then stopped working.

    It is entirely possible that some change triggered a BIOS(?) bug, or
    even that a BIOS upgrade caused the breakage, of course.

    I'll try to try out the hardware in another Linux box - it may take a
    while, as I have to find out who at work has liberated their machine
    from corporate IT. :-)
