Hi,
a quick question, how to clear the b43?
a detailed background stories as following:
I installed the b43 following the advice given by list,
mainly from
http://linuxwireless.org/en/users/Drivers/b43
it WORKED.
but yesterday I removed the old kernel 3.2-rc6, which is the one b43 worked,
and installed the 3.2 from kernel.org. I guess it's latest, than 3.2-rc6 ?
I don't know how to remove the b43 since the trial of
make uninstall in pathTo/b43-fwcutter-015 not work.
so I just did something like make install again, and then

dmesg showed me:

Kernel modules must be built for the kernel you are using. Yes, switching from
3.2-rc6 to 3.2 removed compat-wireless. Reinstall it under kernel v3.2, and your
4313 will work again.

You are right. I'm lost. And I'm the person who never learned how to read map. I mean in daily life, I have map in hand, GPS. But sometimes I can only find the way by asking people. Sigh ...

If you want to run that device with 4331, you need code that will not be in a mainline kernel until 3.3-rc1, which will not be available for about 2 weeks. The kernel you need is the one found in the git tree of wireless-testing, or you need to build a recent compat-wireless package. I suspect that is what you did with 3.2-rc6.
Yes, did remove old kernel also removed my old built compact-wireless?
Sorry im not in front of computer. Just check email by phone.

3.2-rc6 is enough actually. It's just matter of enabling HT-PHY support:

You are very confused. The only thing you can "uninstall" is the firmware
cutter. The driver b43 is part of the kernel. Installing a new kernel gets you a
new version.
Your problem with the 4331 is that you are getting your kernel from the wrong
source. If you want to run that device with 4331, you need code that will not be
in a mainline kernel until 3.3-rc1, which will not be available for about 2
weeks. The kernel you need is the one found in the git tree of wireless-testing,
or you need to build a recent compat-wireless package. I suspect that is what
you did with 3.2-rc6.
