Is my KVM failing? I have a ATEN 8 port KVM connected to a wired Apple keyboard and a wired Logitech mouse. I turn the KVM off when not in use. Lately I have noticed more and more often the KVM does not respond to keyboard, to a point now where the Apple keyb is not detected at all. The keyb and mouse are wired with extension cables, have been running this year for few years. Now I've tried a brand new ext cable from Amazon as well as a a short Apple (the thicker cable). I've also tried another Apple wired keyb. If plugged in directly to the switch the keyboard is recognized. I could move the switch to my desk, but that would require purchasing longer "client" cables.
