You mean a USB Mobile Adapter for a Wireless service like from Verizon or ATT correct ???
As far as I know these are only Windows compatible, perhaps they have some Mac support now.
So what distro of *nix are you running on that Asus machine ???
Asus only seems to indicate some of their models come with XP Home and nothing about the Linux Distro they use, I suppose they leave that up to the user
