VMware Workstation (commercial), VirtualBox (free, open source), and Windows Virtual PC (free) can all route usb devices directly into your virtual machine. Just install a 32-bit OS (even XP if you wanted), give it a marginal amount of RAM and you can do what you need. I've done this to load legacy applications that didn't support Windows 7 and my brother actually loaded his old Creative webcam (with no 64-bit drivers) and used Skype through his virtual machine.
