pepedog thanks for caring
Yes the RPi has enough juice with a stable 5v through a 2A custom power source and the DAC is powered by its own means, additionally the Edimax not working completely is tested with only the Edimax and a 32GB USB pendrive.
Hereunder are the steps I had written in the other thread which in my limited knowledge should indicate a driver has been loaded (but is it the right one ???) but as you see other than the wifi0 existing and can bring it up I cannot either scan nor associate ...
Thanks for any further help.

Not connected.
AND HERE is the step from the archlinux wiki where things start to go wrong:
[root@archphile ~]# iw dev wlan0 scan
