NetBSD lace 1.5_BETA2 NetBSD 1.5_BETA2 (GENERIC_SCSI3) #52: Tue Nov  7 00:43:53 MET 2000     root@flambard:/usr/src/sys/arch/sparc/compile/GENERIC_SCSI3 sparc
Optical mouse which came with Sun Classic always complains of
"ms0: input overrun". I have three optical mice and I exchanged them.
The results were the same. When I connect the optical mouse to Solaris 7
on Ultra 5, it works fine. The result revealed that the optical mice
themselves are not out of order. In contrast, a ball mouse from
Ultra 7 works fine NetBSD 1.5_BETA2 on Classic. This result showed that
a connector to a keyboard is not broken on Classic.
Whenever I connect the optical mice to Classic.
Sorry, I don't know how.

Feedback mail is bouncing. Anyone have one of the old Sun optical mice?

 I often see this type 4 keyboard/mouse and SS1+.
 But it looks that optical mice could actually send stream data
 on some condition (no proper hysteresis on threshold?),
 so it might be better to disable the message for mice
 (dropping some data would be harmless on mice).
