BenQ DW1640 not being recgonized (through external USB storage device) Help!

I have been using nec-nd2500 A (as an external writer, installed inside a USB 2.0 External Storage Kit,aka ADS USBX804).That works fine,however when I replaced this writer with a BenQ 1640,the drive gets power and I hear it spinning but windows does not recogonize it.

I see the error: This device cannot start. (Code 10)

Tried all of the following:
So I deleted INFCache.1 (reading elsewhere) and xp reinstalled it automatically. I have tried all the jumper positions (C/S,M,S),no use.
Tried uninstalling and reinstalling the drive (through device manager),didnt help

Please tell me how to fix this problem as I am stumped :frowning:
