Ok, on one log it can't be bound and connected to, on the others it can be 
bound. I think you have 2 wpa/NM/whatever processes there which try to assign.

The driver doesn't cope with scanning at all. It doesn't support passive scans. 
It's a mac layer who scans (sends probe request for each channel and listens for
