Duncan, plug the mouse and KBD directly into the PC affected and see if all is well. I have a 4 port KVM switch that acts flaky with my Logitech optical mouse so I just plug the mouse into the front USB port of the box I want to use it on and disregard the KVM (my cordless mouse wouldn't work with it at all). My KVM works fine with my KBD and video so I can live with the mousy antics. Best!

I have been trying to find an intermittent problem for the past 8 mo. or so. The PC(2) responds to the Reset Button or an OS Restart command, but, sometimes it boots back up with no mouse (ms ps/2 optical), or, no mouse and KBD. I have to repeat 2 or more reboots to get the mouse to "light up."

3 similar mice and 3 in-service KBD's swapped thru have not affected this behavior.

The mouse, KBD, and Dell FP connect to the PC via an Avocent/SwitchView 2-port KVM switch. I suspect that this KVM switch is dying on Port2. I suspect this because I just had to replace the PC2's HD and rebuild the XP OS from scratch. I can not believe that even the old MS Mouse and KBD drivers are bad from the git-go. Yes, I still see this odd behavior with a new build!

I could suspect a possible early death of the PC's m/b (mouse/KBD circuitry), but this m/b has been stone solid since its' birth. I suppose I should eliminate this by swapping the cables for PC1 and PC2 at the KVM switch.

Am I on the right track?
Best,
Duncan
