No at the time I don't think I powered it off, and I suspect that is probably what went wrong. The windows driver probably didn't like the state of the chip after linux had poked it.

Well it must have just been the state of some registers then.

I suspect I can't. I still can't make it connect successfully to anything yet, but that could just be a configuration problem, or it not liking WPA encryption yet.

I have just mainly seen messages about devicescape from the ralink driver.

Sometimes I might be. At least on the days I have to deal with problems in Windows (it's not even my machine, so I don't get to pick what it runs all the time. :) I haven't had particularly much luck getting a stable wireless going on linux yet, although I haven't put much effort into it yet either. I figure in a couple of years there will be so many wifi devices around that wireless won't work anymore anyhow so it isn't a high priority. I like simple trustworthy wires.
