Also, this cgminer usually takes long to find the hardware (about 2 minutes) and if I set the frequency to 0A81, the ants aren't even detected.
I noticed this as well. It is especially bad if you have both BE's and ANT's. The BE's have to fail ANT validation 3 times each, and this takes time. I have thought it would be nice to fix that but given that I restart my miners once a month or so I figured I can live with it.
Even if for some reason I have to restart once or twice a week, I can also live quite well with it!!!
I'd even wait for 5 minutes as long as it worked!
(Just got "scared" in the first few times! :p)
Once again, great work, Fractalbc!!
