But the manufacturer didn't have the last word! Not at all. A couple of enterprising hardware hackers - Pierre-Philippe Coupard and Michael Rothwell - tore down a Cuecat, dumped its ROM, and produced their own driver for it - a surveillance-free driver that worked with *any* barcode.

You could use it to scan the UPCs on your books or CDs or DVDs to create a catalog of your media; you could use it to scan UPCs on your groceries to make a shopping list. You could do any and every one of these things, because the Cuecat was yours.
Cuecat's manufacturer, Digital Convergence, did *not* like this *at all*. They sent out legal demand letters and even shut down some of the repositories that were hosting alternative Cuecat firmware.
