I have been tinkering with my 3 sticks, and been using bfgminer on a couple of different Windows 7 boxes. I observed a kind of odd behavior that I thought folks might find useful/interesting..

I had assumed it would always be best to have the sticks plugged in prior to starting bfgminer. I have yet to have example where bfgminer discovers anything on it's initial pass at start up. I then have gone through the process of "adding" them after bfgminer was started. I hade to use the \\.\COMxx reference. They would usually add just fine, and they showed up as an AMU.

Without actually realizing what I was trying, I plugged in a 2nd stick while bfgminer was running. I noticed in a couple of seconds, the LED started to flash. I then looked back at the screen, and bfgminer had automagically added a new miner to it's list and started using it. In this case though, it was a "CBM" miner and not an AMU. I then hot-plugged the 3rd miner and it to was detected and added as a CBM.

I then shut it all down, and unplugged the sticks after letting them cool (no fan). I started bfgminer with no sticks and over the course of 10-15 seconds hot-plugged all 3 sticks and I now have 3 CBM miners running at about 10-11GH each.

It appears to me that hot-plugging is actually "better", which I found surprising.

I agree with the overall consensus that these are great little stick miners.

Thanks sidehack and novak!!!
