I have an USB-RS-232 adapter that when I plug it into my Windows 7 laptop comes up as a ps/2 + USB input device.

How do I go about changing this?

I don't have the original driver disk and there isn't a name on the adapter for me to go to the manufacturers website.

Is there a universal driver that I can install that will make this problem go away?

I've since discovered the adapter is a Cypress Semiconductor product. Web info tells me I bought a paper weight. Time to go buy myself a new one. – Chef Flambe Jun 9 '12 at 17:14

The two most common chips used in USB-to-RS232_serial adapters are by FTDI and Prolific. Try this site for other drivers:
