Hi all.

Yesterday evening I tried John's patch (I manually added those two
lines to the source), and the driver properly loads and it seem to
work.

However.... it would seem that my card died some time in the last few
days. It works for about 10-15 seconds after i plug it in, and then
"dies". I'd say that when it gets warm, it's out of the game.

In Linux after i plug it in, it works just enough time to:
1. detect networks in ubuntu network manager (and return a nice scan
result with iwlist wlan3 scan)
2. starts to connect to my network (and reaches random points in connecting)
3. stops responding altogether, cannot connect, no more results with
iwlist scan, etc.

I noticed this exact behavior in windows too, yesterday morning,
before I tried these patches, so linux driver is DEFINITELY not to
blame.

In windows it very shortly detects available networks, starts to
connect and very soon stops responding and finding networks.

I'll return it to shop to be replaced, and I'll report back when I get
one that works properly.

Also, Larry, I took lsusb -v output during those first few moments
while the card operates properly, hope it helps:

Hin-Tak, I did see the AirLive linux reference driver, but didn't even
want to try that, unless my only option left was ndiswrapper. I know
those manufacturer's "drivers" usually cause more frustration than
use.

Thanks all for your time and help.

Viktor
