I think its effectively a good choice for a standard mouse usage. But when I
want to use a grapic tablet (a wacom intuos for instance), I'll need to get
stylus pressure information as well as stylus unique ID. And if I want to
manage a complementary keyboard (a key pad for instance), I think its the
same problem. Dealing with /dev/input/mouseX and so on seems to be not so
precise than an USB direct access.
So I prefer to use the patch mentionned in Dan Streetman and David
Brownell... or wait for its integration in futur 2.4 kernels...
Thanks,
Olivier
