USB EXTERNAL BOX

I PURCHASED AN USB INTERFACE, BOX THAT WILL HOUSE AN IDE DEVICE. MY OPERATING SYSTEM IS WINDOWS XP. XP WILL NOT RECOGNIZE THIS PRODUCT. THE BOX CAME WITH ONSPEC SOFTWARE FOR WINDOWS 98. THE READ ME FILE ON THE SOFTWARE SAID NO DRIVER NEEDED FOR WINDOWS 2000 OR XP. XP SEES THE USB PRODUCT BUT CANNOT FIND A DRIVER. CAN YOU HELP? I HAVE A WD HARD DRIVE IN THE BOX, SET AS A MASTER.
