Question

I have just purchased an LG GSA-H55L DVD burner in an external enclosure. It is conected to my laptop via USB. I cannot get the Laptop (running XP) to recognize the drive as something OTHER than a generic CD-ROM. I bought this thing so that I could BURN disks. How can I get it to do that? Is there a driver that I can download from somewhere?
