When in XP mode, you need to allow the XP mode to use the specific USB device.
I think As XP mode runs on in 64bit VM it is primarily for
programs that need XP, rather than hardware. If you can't get the 64bit OS to see the hardware it will won't be available to XP mode software.
Unless there are some 64bit drivers somewhere that work, Dave is probably going to be unlucky trying to get it to work.
On the positive side there are better calibrators and software than an old Spyder & Photocal around now. Maybe one of the cheap ColorMunki units referenced here recently would fit the bill nicely ?
