Yes, I have Windows XP and the driver was installed as soon as I installed the drive and booted the PC. And it's the right one (I checked the label, it's NEC ND-2510). So I think that the problem is not in the driver (besides, the DVD-RW worked perfectly on an even older PC with Windows XP system and same old driver). I don't think that installing new firmware will help me in any way... Hm?
