    When recently I've switched to a PS/2 Keyboard attached to a USB
    converter I started to experience strange typos.

    The problem is extra characters sent to the machine while typing
    fairly fast. It can be easily reproduced doing this:

     1. xset r off
     2. press and keep pressed a key, say 'd'
     3. press and keep pressed another key, say 'w'
     4. release the first key
     5. at this point you should see "dwww" which is not what I expect
        ("dw")
     6. release the second key
     7. at this point I see a "dwwww"

    On a PS/2 keyboard connected directly to a PS/2 port (no converter in
    between), this doesn't happen. Unfortunately I've got no USB
    keyboard to try directly without the USB->PS/2 converter.

    I was wondering if this is a problem of the USB converter or a
    problem of the ukbd driver.

    Does anybody else experience the same behaviour?

    Cheers,
