The KVM is probably faulty. If the keyboard and mouse work properly when plugged straight in the PC then that is the likely scenario.

Windows 7 system does check the connection status of all devices connected to it under "Device Stage" which was the new features/functions added to Win 7 OS. Most of the KVM switches currently in the market do not support or feed the continuously update of share devices (such as keyboard, mouse or even speakers connected to the KVM switches). That's the reason why
you only experience problem under Win 7 OS. The Windows 8 OS will have the same issue regarding the keep checking the connected devices status. It may be caused by both new OSs all have built-in support of touch screen display or under tablet mode.

So, the make sure your future KVM switch 100% support Windows 7's or Windows 8's"Device Stage", you need to looking for if they having advanced technologies, such as "USB DDM" or "Dynamic Device Mapping" for USB devices or "Full-time All DDC-EDID" for the display.

Hope this developers' insider knowledge-base can help you to under stand the reason(s) why your KVM work or not work.
