Dear NetBSDers,
   I put NetBSD-2.0-BETA (releng 6/14) on a box which has a usb 1.0 and
usb optical mouse.  When I fire up X I get a lot of these ohci{0,1}
scheduling overruns messages.  If I disable USB in the bios and plug an
ps2 mouse in I don't get these messages.
   Is this a problem with my setup, hardware or bug in ohci driver?
Included is the of dmesg with the USB enabled:
