I have a digital camera but is not being dectected by computer. The serial cable uses a 9 pin port. My mouse uses the only 9 pin port. I have a 25 pin port not in use. I got a adapter to plug into the 25 pin port to use my 9 pin cable. But computer is detecting the camera. Do I have to do something to make this port work.

I assume that you meant to say 'But computer is NOT detecting the camera'. It should work the way you did it. The port might be disabled in the bios. You could try moving the mouse to the 25 pin port. Windows should detect the change.

you did not mention what computer you have does it have usb ports and did camera come with usb cable also i assume you installed all software that came with camera mine came with 2 cd's and two cables a usb and a serial port cable

I just installed one of these on someones computer the other day. using the serial port instead of the USB port put the camera on your COM1 and in device manager it will be detected under your modems. Don't laugh, I did when I saw it there and removed it, then didn't have drivers to reinstall it. Eventually found drivers and got it reinstalled, but look in device manager under your modem. click it open and you should find both your modem and digital camera there. If digital camera is coming up there click on properties and choose to reinstall or update drivers. Hope this helps.
