Belkin Omni Cadre 4-Port 1. Wise Tech mouse of the wheel optical type 1. a. Set up as a PS/2 two-button mouse it works as a 3-button mouse for months of switching 1. b. Set up as a PS/2 Wheelmouse it will follow through on install with the KVM switch, but any switching loses the mouse _When_ I switch back. Easy remedy is ctrl-alt-backspace and Xtart again. Unplugging/plugging does _NOT_ work. 2. I bought a Logitech USB optical wheelmouse because someone said it didn't work. 2. a. It seems to work with a PS/2 adapter right through the KVM switch every time, even as a wheelmouse. 3. I have a Logitech Marble Mouse which looks like a mouse with one huge ugly red eye. It works fine individually connected to a computer, but is lost with every switch on the KVM switch. 4. I have a generic translucent mouse cheap as Hong Kong can make it with two buttons and a broken piece of plastic rattling inside. It works ALL the time. Have never lost it yet through the KVM switch. If the PS/2 mouse port is like the PS/2 keyboard port, it works on SENSING CURRENT Please read the following carefully... It describes how to gimmick a PC as a keyboardless server without disabling keyboard test on boot. (I have an IBM and disabled keyboard test on boot and it started crying about no pointing device, so I tried this gimmick on the mouse port with 5% resistors. 10Kohm worked, 12.2 Kohm worked 13.3 Kohm gave erratic performance, and 15Kohm did not work at all, NOR did 5.6Kohm. So the KVM switch may either supply a resistance in series to the mouse or possibly in parallel to it which takes some mice with some options out of the range. Strangely, the ones that seem to demand a lot of current work better with the KVM, so my guess is that it is series. These optical mice take current to work the laser diode, and the logitech marble mouse has a very very low-powered diode to read the spots on the ball. Electronically switching KVMs do not appear to have this problem, only those with the mechanical switches.
