Query: Keyboard connection dies quickly, 2 out 2.

This switch uses keyboard combo command to switch between two computers. In my experience with 2 of these, both failed within a couple of days--the keyboard port was completely dead.Must be a systematic flaw somewhere from all the reports on this issue.Keyboard: MS Natural Ergonomic 4000Mouse: Logitech V200
