I can't get Win98 to recongnize my serial mouse. I have a Kensington Scroll mouse that has a serial port adapter. I've also tried a straight, no-frills serial mouse, but the OS still doesn't recognize a mouse. It is an Opti Viper mb with onboard com ports and an onboard parallel port. The com ports and parallel port install fine, but the mouse doesn't. I also have an ISA card with com ports and a parallel port. I've tried disabling the onboard stuff and installing this card, but the mouse still won't be recognized.

Any suggestions? Thanks.
