I am not sure what would cause this, but here is a question that needs to be asked (Please don't be insulted by it) but is the power on the drive turned on? I just hooked one up to my XP test system and it worked fine, after I remembered to turn the power on. So I figured if I forgot this, this could also be someone elses problem. This USB CD-R drive shows up under my XP system without any problem in My Computer or Windows Explorer.
You will have to download this ASPI driver for Microstudio to recognize the drive:
