I am using a USB-to-serial cable and I have a tip for you:

If the thing came with a drivers CD, make sure you are using that driver. Don't upgrade, or use an alternative. The cable I have registered as a "Prolific USB-to-comm" or something like that, and Windows automatically used the Microsoft-written driver for it. I was having communication issues, where there was no response from whatever I was talking to (the CMUcam, the RC). I upgraded the drivers with the ones on the CD, and it has worked flawlessly since then.

Also, you could try to go to the manufacturer's website for drivers, but I tried that on another machine and the best drivers produced blue-screen "stop" errors...not fun.

Good luck with this, because I know how much of a pain in the *** these things can be.
