mouse cable length

Hi, Apparently, there is a limit in the mouse cable length: a 1.8 m extension cable works but a 10 m one does not. Is there a workaround? Configuration: Logitech PS2 mouse, SuperMicro P4DCE motherboard. Two mice and two 10 m cables tested. Both the keyboard and monitor work OK with 10 m extension cables. In my case, I'll probably move the furniture and use the 1.8 m extension cable but for an other computer I may need a 20 m extension cable. I don't think it's OS specific (SuSE 8.1 is installed there) but I haven't tested it. -- Alexandr.Malusek@imv.liu.se
