I though I would be able to use my Fujitsu ScanSnap s510 with my Windows PC virtual machines, but when I installed the software in the order suggested to my Windows 2003 virtual machine, and when I plugged in the USB to my Mac and assigned it to the virtual machine, and it recognized it as a new hardware device, I thought I was good to go. However, when it tried to load the driver, with the installation CD mounted, Windows said it could not find a driver and could not use the device (with a message like 'it may not work properly'). Well, it does not work at all. So, how do I troubleshoot the software, the USB, the lack of a driver, etc.? Thanks.
