    Eh, that info is already trivially available from my original mail:
    uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 3
    [...]
    input: USB Compliant Keyboard as /class/input/input0
    input: USB HID v1.10 Keyboard [USB Compliant Keyboard] on usb-0000:00:1d.2-1
    input: USB Compliant Keyboard as /class/input/input1
    input: USB HID v1.10 Device [USB Compliant Keyboard] on usb-0000:00:1d.2-1

    Yes, obviously the keyboard is attached during boot (and has been connected
    to the same USB port basically since I first installed the machine...).

    No idea. I could try this I guess if it will really provide useful info.
    Somehow I doubt that in this case.

    Will include that in my reply to Alan's mail.

    Cheers,
