Disabling Legacy USB Support

Hi all,

I have a portable drive which connects to the system via a USB Y cable (with two male USB-A connectors - one draws power to aid the main one and give the drive extra power - both need to be plugged in). In OS X, it's recognized immediately after I boot up, but in Windows I must unplug both connectors and plug them back in before Windows will see it properly.

I spoke to SimpleTech/Hitatchi, the manufacturers, and they told me I needed to disable Legacy USB Support in my system's BIOS to fix the issue. Of course, Bootcamp doesn't have BIOS.

Is there any way I can do this?

All help is appreciated.

Macbook Pro, Mac OS X (10.6.3), Windows 7 Professional, device is a 500GB SimpleTech Portable drive made by Hitatchi
