I have standard PS2 mouse and keyboard, but I am running them into a small, cable based 2 port KVM type of thing. The KVM is not the issue, as I removed it and went with straight mouse and keyboard and the same issue.
I can't remember the exact message, it is very quick but something like it cant find the default and is going with the other???Not sure. I'll reboot and try to catch it...but it is quick.
