Ok, you obviously don't use Linux. The USB driver would have to be released as source, then compiled to run in a completely different OS. It's not easy. Certianly not just "recompiling the kernel".
Anyways, I asked originally because the PC or whatever computer it is connecting to the 'net should not even be an issue. I just don't see why it matters what OS is running, as long as you have a WiFi connection to the internet. There's no reason to limit it to PC-only, because all you need is a standard WiFi connection. If that happens to be through a PC, Mac, Linux box, whatever.. it shouldn't matter. You may not even have a computer! It might just be a wireless router plugged right into a DSL modem or cable modem, but that is a perfectly servicable internet connection.
Please don't respond on this thread unless you understand networking. Let's try to keep the chaff to a minimum. Thanks!
