Not running on startup

Thanks tomj23 but i had already tried that, sometimes it would work fine 3 times in a row then stop, sometimes i would only need to take the kwm usb cable out and back in once to work, other times i would have to detach all usb devices and try about 4 or five different connections. i would even get any system sounds or messages saying new device found or disconnected!"£$%^&* Saying this i have found a solution for now, the mouse i was using was a Labtec usb interface which had a serial adapter to connect to the kvm. i switched this for an MS mouse with plain serial connector and i havent had the problem since. 10+ boots and counting. can't test with any other mice as this is all i have. happy for now anyway even though i'm back to my old rollerball mouse, have to give it a good scrub.

I occasionally have a similar problem with a couple of my KVM?s and I think it relates to the circuitry in the KVM that is supposed to fool the PC into thinking a mouse/keyboard is attached. Windows doesn?t see the mouse so it doesn?t load the drivers unless you force it. What works for me is to just start the PC and switch the KVM to that PCs port and leave it there till the computer finishes booting. Then its safe to switch to the other port, probably not the elegant solution you were looking for but it works every time.
