Well the boss is putting the preasure on me to use one of the cheaper alternatives for out product, however i dont really want to since i believe that usbwiz is the superior product.
Not to worry, i will convince him that usbwiz is the way to go

.
EDIT - Oh one question i did have. What does usbwiz do in the case of a composite usb device? Like a camera that also has mass-storage?
