I know exactly how you feel. =)

Me too - and it'd mean that we don't have to do AP-mode firmware
loading tricks like in mw8k. But if we can't get that then some
firmware is better than none.

I think I may have a simple firmware extractor at home that I pulled
from *somewhere* when I was working on this last time. We can see if
it does anything with those files. I believe I have at least two
different Windows drivers at home - IIRC, one of them is *just* the
files needed for this extractor.

Nice!

Out of curiosity, what brand and model number is it? I might see if I
can obtain one for testing / development or whatever. (Not that I
really have time to write a driver, but I can test at the very least)

Thanks,
