I did this test a few minutes ago. Actually it seems to associate (iw
said "connected") but after a while the device got disconnected again.
Of course, it works with my working drivers (I'm connected right now).

If you want I can retry with another AP this evening.

Here you can find the sniffed traffic (filtered by my MAC) of the test:
www.ritirata.org/ordex/association.cap
I tried to associate multiple time.

I hope it could be usefull
