@ckolivas: Since I upgraded the firmware to 0.4RC (from you) and 0.4RCx (from Hashfast) cgminer (all versions, didn't try 4.01 yet) can't see my babyjet anymore (I'm on Windows 7)

Is this a known problem with cgminer on Windows or should it work / am I doing it wrong?

Edit: I just tried 4.01 with Ubuntu 64, worked right from the start.

@To all the people hoping for firmware miracles: Both firmware releases didn't fix anything for me, in fact it hashes a little bit slower with the new F/W. Overclockability seems the same. IMO, if your BJ is hashing ok & is more or less stable, you should wait for the official release from HF.
