I have installed and re-installed XP mode and virtual machine on a new Windows 7 program. I want to install an OLD program that worked in XP. Unfortunately, when I try to attach the USB floppy it indicates that it is a shared drive and that attaching will disconnect it from the computer. When I tell it "yes" it gives me the error "could not attached the USB device. You can attach the USB device to a differant USB port or restart the virtual maching and try again. I've tried both, many times. Neither works. Thinking it was just a problem with my USB floppy drive, I tried with a flash drive. Exact same problem.
