	that is not recognized by netbsd.
	The reason is, that it identifies itself as a pointer device and not
	as a mouse. I do not know what the difference between a pointer device
	and a mouse device should be, but the appended patch fixes the problem
	for me. But it might still be very wrong...

>How-To-Repeat:
	Try to use a mosart wireless mouse

 Modified Files:
 	src/sys/dev/usb: ums.c

 Log Message:
 Apply patch from Matthias Pfaller in PR/42546.

 The USB HUT v1.11 document states that:
     "Typical system software will search for application
      collections tagged with either a Mouse or a Pointer usage."

 This patch adjusts ums(4) to match not only on
 the Mouse usage, but also on the Pointer usage.
