That's what the link gives.
I don't have XP MODE up at the moment but when I connected my old USB Microscope to use under XP MODE I had to use the XP MODE MENU item to attach the USB device to the XP MODE virtual machine.
I'm currently running windows 7 as my main OS. But i needed windows xp for my project work. So I installed Xp using virtual machine and it installed perfectly. I wanted to connect an micro controller board via usb port. I installed the usb driver for the board successfully but Win xp is not recognizing the board. Any idea of what might be the problem ? I will give the link of the usb driver file for reference.
