On a Raspberry PI under OpenELEC I can not get to run the thing. Reingesteckt, it is recognized networks are displayed, but registration in WPA2 protected network is not possible.
Forums and wikis for 4 days up and down searches, seems to be a problem with the driver (8192cu). No one gets the part up and running.
At the same time plug in the PI is quite warm.
For OpenELEC not endorse (unless someone hats made to run times and can bring the solution here).
