Thanks for this info.

I actually think that we have some hardware incompatibility here.

The card did not only refuse to work with hostap, but it didn't work with 
orinoco_cs either. To rule out problems with the old 2.6.13-rc2 I upgraded to 
the kernel to 2.6.15-rc7 and still it didn't work.

But in the same hardware (with Linux 2.6.15-rc7) an Intel WCF2011B card 
worked. That card uses the spectrum24t_cs driver and therefore hermes.c. So, 
with one card hermes.c worked, but with another card not. Sounds quite fishy.

My current assumption is that either we have some hardware problem here ... or 
that this card has a different way to specify internal state and that 
therefore then numberous

  while (some_test_failed) {
	usleep(X);
  }

kind loops in hermes.c and hostap_hw.c won't work as expected and give me the 
a feeling of "this rotten piece of code hangs!".


BTW, here's a log of a hermes.c with lots of debug printk's:
