My Problem:
I am trying to use a Digilent Inc. BASYS2 FPGA development board. I am able to connect the USB device to the virtual machine using Fusion, and Windows successfully detects the device and installs the driver. When I use Digilent's board communication software (Adept 2.0), however, I am given the error, "Initialization Failed. Check connections and try again.". This problem always occurs, and is not intermittent (and occurs independent of which USB port is used).

Additional Information:
I have access to other FPGA development boards from Digilent Inc., including the NEXYS, NEXYS2, and the
BASYS boards, all of which work correctly (in the same XP and Vista virtual machines).

The major (relevant) difference between the boards which work and the one that doesn't is that compatible boards use a Cypress CY7C68013A USB interface, while the incompatible use an Atmel AT90USB2 interface.

I have tried using the incompatible boards with another MacBook Pro with XP Pro via Boot Camp, and the boards work correctly (so hardware is not at fault).

Fusion USB Debugging Information:
I've included snippets of the vmware.log file for the XP virtual machine for cases where a compatible board worked and where the incompatible didn't (by adding usb.analyzer.enable = "TRUE" to the .vmx file). Note the error messages (in bold).

Other Notes:
I'm not sure the significance of this, but note that in the debugging output, "family" is listed as "vendor" for the compatible board, while it's listed as "other" for the incompatible one.

I hope someone can point me in the right direction.

Again, thanks in advance for any help you can provide.
