So I got my first erupters today and spent about 2 hours trying to take the advice in a bunch of threads about settings them up with cgminer. Silly me tried to set them up with the latest version of cgminer 3.3.1. Since the -S command was removed a few versions ago it seems like you are now supposed to get a perfect install of the drivers and then it magically detects the USB devices on start up. But this didn't work for me, and others in some threads had problems with this too.

So I followed this guide http://rdmsnippets.com/tag/install-block-erupter-on-windows-7/ to the letter and used the older 3.1.1 and it worked more or less perfectly.

Not sure how support for the USB miners will progress with new versions of cgminer. I suppose its best to just leave it alone since it works.

Also I used the D-Link DUB-H7 hub and it works flawlessly. Running of my netbook (~13 watts) which runs 24/7 anyway, seems like a good host.
