    Fair enough, I played a little trying to massage the original descriptor
    but could not find a sensible solution - so I guess we'll have to provide
    a full replacement.

    I don't see the need to comment the original/replacement blocks, so
    probably a simple 'hex block' would be good.

    Regarding the replacement, you appear to have a lot of unnecessary code
    there. You could try with something like:
    --
    ...
    +0x09, 0x39, /* Usage (Hat Switch), */
    +0x81, 0x42, /* Input (Variable), */
    +0x75, 0x08, /* Report Size (8), */
    +0x95, 0x08, /* Report Count (1), */
    +0x65, 0x00, /* Unit, */
    +0x06, 0x00, 0xFF, /* Usage Page (FF00h), */
    +0x26, 0xFF, 0x00, /* Logical Maximum (255), */
    +0x46, 0xFF, 0x00, /* Physical Maximum (255), */
    +0x09, 0x01, /* Usage (01h), */
    +0x81, 0x02, /* Input (Variable), */
    +0xA4, /* Push, */
    +0x05, 0x01, /* Usage Page (Desktop), */
    +0x95, 0x01, /* Report Count (2), */
    +0x09, 0x31, /* Usage (Y), */
    +0x09, 0x35, /* Usage (Rz), */
    +0x81, 0x02, /* Input (Variable), */
    +0xB4, /* Pop, */
    +0x81, 0x02, /* Input (Variable), */
    +0xC0, /* End Collection, */
    ...
    --

    Cheers,
    Simon.
