I actually didn't know that, thanks for speaking up. The ISPs I spoke with were adamant that only a Windows system could be used since the stick required drivers and those drivers were only available for Windows.
Yeah, the relevant Linux driver to support this "windows only" device is USBNET.
R800 support will probably go much faster than any other, as CTRL+C CTRL+V is now possible
If i understand that correctly, it's supposed that the different hardware generations use the same architecture for the basic functionality. Sounds okay. I wildly guess that the real deal is the opengl/3d part and the video acceleration.
