I have exactly the same config with one of my laptops. You need to make sure you get one that actually converts the signal properly to USB. Startech.com makes a good one that I use. Model is called (who would have thought it?) a USBPS2PC. You can buy them from lots of sources. Just Google for it. Cost about $15 bucks if I recall (has been awhile).

Worked fine for me.

Good luck
