What are your symptoms?  If memory serves there are (at least) two USB 
mouse related problems that have been discussed recently.  One manifests 
itself as no mouse movement whatsoever; the other causes erratic mouse 
movement.

If your symptoms are the latter, I'm afraid I won't be much help; check 
the archives for messages about (IIRC) ums interrupts either being 
dropped or not routed correctly.

If your symptoms are the former, they may be caused by the problem I'd 
been slowly tracking down.  Could you also:

-Move, click, whatever, the mouse a few times and send me the ums_intr 
debug messages from dmesg.

-Does your USB receiver also contain a keyboard interface (ukbd)?  If 
so, does it make a difference if only the ums (i.e. *not* the ukbd) 
driver is compiled in or loaded?

Thanks,
