Hello Alexander,

Our hid parser sometimes has problems dealing with multiple report IDs, and
our parser
is different from the Linux one.

Could you please dump the report descriptor of your mouse and post it here?
You can use this kernel module to do it:

# tar xzvf krepdump.tgz
# cd krepdump
# make
# kldload ./krepdump.ko

Then plug in your mouse at this point, the descriptor should be written to
your console.
