Of course. Naturally it's near impossible to prevent people from tweaking the software.

Yes it can. You're confusing the software with different or modified software. Different things. And by the way, if you modify the software to defeat the restrictions you are committing a criminal act, or you would be if you did it in Australia.

One way they do that is via the driver. > The driver can help, but as long as it asks the user a country > setting, its enforcement is nearly nothing! You're correct, but that's still how it is. In fact, some manufacturers provide country specific drivers simply to shore up this weakness. (They'd only do that to protect their regulatory approval.) > Another example.

Is the manufacturer responsible? Are you asking if the manufacturer could lose their licence to sell the product? It could happen. Regulators do wield significant powers. > If you're right, he is and must pay, remove that device from shops and > replace sold ones.

This is why manufacturers view open source licences dimly in certain markets, of which radio communications is just one example. - To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
