The problem is that if I set the switch to an empty channel (no signal to the monitor then) for longer than about eight hours overnight) and then go back to the channel the 9.1 is on I get no keyboard or mouse response. Sometimes I hear the two system beeps when the usb is initiated sometimes not. I plugged in another usb keyboard directly into the 9.1 machine-no response. So far the only way around this is to hit the reset button. Any ideas on what is happening here? Thanks, Jerome
Sounds like the old ps2 issue which was solved by switching to console and back to X. But if its a USB KB it could power down when disconnected and fully discharge. In that case it can not sustain. BTW is the KVM directly connected to the USB KB or is the KB converted to ps2?

Yes, the KVM is directly connected to the USB KB. So are you saying
usb mouse and keyboard lose energy over time if not powered by the KVM switch? Thanks, Jerome
Thats what I was told. If its a breif switching then the system just looses synchronysm and the switching to console and back to x forces
hardware to be recognized. But your using a USB KB not PS2 so the

problem could be an issue.
Does google have anything on your make and model of KVM??

Jerome, This no name KVM retains power to devices less than 8 hours which indicates capacitors discharging. We are left then with googling on the exact model kvm (if there are any distinctive marks) and the devices attached to it. what is the make and model of the KB? have you tested it on another machine? Did you change any hardware since this problem arose or was this always a problem? CWSIV
