Hi Môshe van der Sterre,

Thanks for you answer.

This mouse can store keys in their internal memory but can also load
profiles from a local file.

When using profiles, keys are not stored in internal mouse memory. I had
tested it in other PC running Windows and when I disconnected from USB
and then connected to my PC running Linux verified that keys where not
being detected.

Only when I stored the keys in mouse memory (without using profile) I
could catch them using xev or showkey. This is why I think that could be
a missing feature for linux mouse module.
