I don't think drivers are an issue, what we wants to do is use an app that uses the usb ports, and he wants to use this app from wine. So he wants to write an interface for wine, that would take driver calls from the program and forward them to ioctl(whatever) so the app will work with the usb ports, or at least thats how I think it may work. I don't think it's easy to find USB ports not supported by linux now days, but wine isn't usb-aware.
