Update: To activate USB support within the VB for :CueCats and other barcode scanners -

Simply connect the device before initalizing the virtual environment and then right-click on the USB cable icon at the lower right of your VB window. Now left-click the name of the device so that a check mark appears beside the name.

Wait a moment for Windows to load the device driver and a balloon will appear once it is ready to use.

Let me know if you have any issues with your USB devices. Thanks!
