ckolivas: cgminer 4.0.1 fails without the new firmware with the OP_NAME error code. It appears in the code that there is supposed to be a mechanism to fall back if the OP_NAME isn't supported, but that doesn't seem to get called or work.
Right, it's meant to be complementary to the new firmware... but it is still supposed to work without it. Are you running it via a pc plugged into it and it never starts the device at all with 0.2 firmware?
