So I purchased 4 au3 miners that I didn't know had a reputation to be very unstable. cgminer would mine really fast when I only had one plugged in. plugging two in didn't affect my speeds much. Problem was when I have more than two plugged in. everything slowed way down and I started getting errors.
I ended up loading my .bat file 4 times to see if each .bat file would pick up a different miner. My thought is that cgminer does not properly handle I/O interrupt requests when using more than two miners.
