I thought so too, until I had to connect this thing to a pc.
To the original poster: I have a usb scanner and the thing behaves just like a keyboard device. You don't really need it to see if it works with your application. With my device, every time I read a barcode it sends the characters to the control that has the cursor in it and then it sends the Enterkey code. Just find out how your scanner behaves (for example in notepad) and make sure your application can work with it.
