I run these KVM swithch on a Windows XP Home PC and a laptop with Linux Fedora Core 4. The Windows PC, the device is working properly. Even my cordless (IR) keyboard works flawlessly under Windows. But as soon as I switch to Linux, it is the mouse (Logitech PS / 2, not cordless, not optical) a disaster. The cursor jumps as if stung on the monitor from oats. The keyboard makes Linux also problems. The keys bounce from time to or do not respond. Is again switched back to Windows is all right. The picture on my 30 inch LCD (1280x768) is good. I have to now work in two mice use to communicate with the KVM. No targeted solution in my opinion. The manufacturer should improve the unit. Imerhin he indicates that Logitech mice are supported by this unit to 100%.
