I can get my AMU to mine at ~ 400Mh/s using cgminer. Zadig driver overwrite/installed.
I can't get BFGminer to recognize it. (Windows XP SP3 dual core Dell w 3GB ram)
Running bfgminer -D -d? -T from command prompt shows the device but does not recognize it:

"[2014-01-17 20:09:44] lowlevel_scan: Found vcom device at com:3 (path=\\.\COM3,

Also, how does one get the named configuration file used when starting bfgminer?
Thanks
