Why not?  Are you confusing mousedrv and mousedev?
Comment 2 Ryan C. Gordon 2011-08-21 07:26:44 UTC 
Resolving bug as INVALID. This appears to be a misunderstanding of what is happening in that piece of code. If this is incorrect, and you feel that this code is in fact buggy, you are welcome to reopen the bug.

Thanks!
