Okay, thanks; so now I know that it's not just badly designed hardware  
that may do this. My device, however, is not a smart-phone or some  
other consumer device: it's a scanner with a rotating drum on which to  
mount flexible, reusable photographic plates from an X-ray machine.  
It's rather expensive too. Of course, it only works with a Windows  
application. Can you imagine a legitimate reason why a machine like  
this might keep flipping its product ID?

Cheers,
