    udevadm monitor output is:
    monitor will print the received events for:
    UDEV - the event which udev sends out after rule processing
    KERNEL - the kernel uevent

    one thing I found out is that this keyboard has some special anti
    ghosting function for some keys. Where you can press multiple keys
    simultaneously
    and they are all recognized. This is apparently great for gaming. Which
    I'm not interested in...

    Cheers
