I am using AO 1.4 with the Theyscon USB Driver for the Berkeley Aplha USB ( Driver version 1.26.0 / DLL API ver 3.2 ) . 1 thing to consider it to get you system up and running with out AO installed. Make sure your PC outputs via USB into the Berkeley (green lights on) before you install AO. I followed the instructions exactly in the AO manual, and all worked perfectly (and I'm in minimal server mode btw, for WASAPI to work). Also make sure that when you do install AO, your computer is actively connected to the Berkeley USB.
