Cannot Use USB in Virtual PC 2007

I just discovered that you cannot use a USB drive in Virtual PC 2007. I need to find a way so that I can access the file from the host instead.
Some quick fix:
1. Install Virtual Machine Additions on the Virtual Machine OS (Guest OS).
a. Start the Virtual Machine first then go to Actions menu of the started Virtual Machine's console, Action then Install or Update Virtual Machine additions .
2. This will install Virtual Machine additions on the guest OS. Once this is done, you need to restart the Virtual Machine's OS (guest OS). Then proceed to settings...
a. From Virtual Machine's console - go to Edit, Settings then Shared Folders. It is here that you specify all the drives/folders of host OS which you want to share with Virtual PC's OS (guest OS)
