Does an optical mouse work in a serial port?
I’ve never seen a serial optical mouse. As far as I can think of, the serial port doesnt supply any kind of power. Therefore you have to go usb. If your concerned about using up all your usb ports, buy a PCMCIA USB 2.0 4 PORT CARDBUS HUB ADAPTER. That will add an extra 4 usb ports to your laptop. The only drawback is that if your laptop has only one PCMCIA slot instead of 2, and you rely on that for wireless internet, then you have to sacrafice one or the other.
