Although it will surely work for scanners that use that code, there's no way 
to guarantee that all scanners behave that way. Their implementers are free 
to code whatever they want in the driver. So while this solution works for 
devices that use the usbscan.sys, it doesn't cover other devices. I don't 
know any statistics about who uses usbscan.sys and who doesn't, so maybe it's 
all a moot point.
