Thanks... Yes, it works, but staging scares me.

I found card compatible with ath9k_htc driver, that works well on PC,
and is even listed as supported by atheros. Good.

Unfortunately, it does not work that well on powerpc mpc5200b. (I'm
using recent wireless-testing tree).

I can do scan just fine, but can not actually asocciate with the
accesspoint. Nothing too useful in dmesg, only:

Freeing unused kernel memory: 176k init
warning: `named' uses 32-bit capabilities (legacy support in use)
process `named' is using obsolete setsockopt SO_BSDCOMPAT

Any ideas how to get more verbose debugging?

Diffences to the mpc5200b board are:

a) it is PowerPC, thus big-endian board

b) it only has USB1.1 controller.
