hostapd does not use any BusyBox functionality, so I don't think this
has anything to do with BusyBox.
Which driver are you using in this device for the WLAN hardware? The
debug log seems to indicate that the driver could have quite a long
latency in reporting TX status for frames and this can result in a race
condition that prevents the association. A workaround for such driver
behavior was adding in the current development branch, so I would
recommend testing with a snapshot from the 0.8.x branch.

This shows the race condition. That "frame from not associated STA"
should not be there, i.e., the assoc_resp cb should show before any data
frames are received from the station.
