I did not want to dump that 8 MB file on the list.

Strange.

Perhaps Chaoming knows something about this output. All I know is that you now 
have the latest driver.

If you apply the attached patch, it will log the firmware name. That will tell 
us what cut you have. If you have quilt installed, you can "quilt import 
filename" and "quilt push", otherwise just use the patch utility. I checked and 
the version of the firmware files in this driver match those in the 
linux-firmware git repo.

 From your name and E-mail address, I would guess you are in France. If you were 
in the US, I would send you one of my standard cards in exchange for yours so 
that I could sort out the driver for it. Perhaps that would still work.
