When I plug the dongle (TP-Link TL-WN321G) into Debian Sarge, dmesg shows a single line on 'high-speed' USB. Nothing else. So I guess, there is no built-in driver !?
So I installed wireless-tools and ndiswrapper.
Now I can 'ndiswrapper -i rt73.inf' and it will create the directory in /etc/, and 'ndiswrapper -l' will show the installed driver. But no hardware. No good, I guess.
'modprob ndiswrapper' will not finish (hang), but lsmod will show two lines in another terminal.
iwconfig shows just lo eth0 and sit0 as 'no wireless extensions'.

It should work, it also says so on the box, but without any specification and no Linux instructions in the manual.

I have to confess, though, that I plugged it into my wife's XP, inserted the CDROM, and there it was. So it works.
Which makes it the only device I saw in the last 5 years that actually installs *much* easier on Windows, and s**** on Linux.

Does it ?
