I received my 4 units a few days ago. Thank you.
I had trouble getting it to work with cgminer right away. So I was using BitMinter for a few days at first.
The default Windows cgminer builds appear to require OpenCL.dll installed on the system. I built from source without that dependency, but still couldn't get it to work. It appears that for com ports above 9, you have to list them in the arguments as -S \\.\comXX. instead of -S comXX. This was in the README. I should have read it more closely at the beginning. It's working fine now on my Windows desktop.
Cgminer is much less resource intensive than BitMinter, which ran under Java. I also have an Asus RT-N16 router with TomatoUSB firmware on it with Optware installed. I've read about people running cgminer under OpenWrt. Anyone know how to get cgminer running under Tomato?
