This mouse has a horizontal wheel that requires special handling.
Without this patch, the horizontal wheel acts like a vertical wheel.
In the output of `hidrd-convert` for this mouse, there is a
`Usage (B8h)` field. It corresponds to a byte in packets sent by the
device that specifies which wheel generated an input event.

Hello,
This is the first patch I send to the LKML.
The mouse I have is quite old, I got it somewhere in '00s.
Greetings,
Mateusz
