FBWF with USB removable drive

[Guest]

I have FBWF enabled and running properly on my build. I plug a USB drive in
and everything continues to operate correctly. If I rebboot the system with
the USB drive still present, FBWF stops working after the reboot. If I
remove the USB drive and reboot, then FBWF starts working correctly again.

I expected the USB drive to be unprotected, but the ‘C:\’ drive to remain
protected.

To make this clear, I am booting from a fixed compactflash disk drive 'C:'.
FBWF works perfect when I only have fixed compactflash disk drive 'C:'. The
removable USB drive is a FLASH memory stick drive 'D'.
