I just got my usb block erupters and I was wondering what is the best tutorial on setting this up to join a mining pool? I'm currently on Windows. I want to be able to mine other alt-coins that uses SHA-256.
Here's a decent bitcointalk thread: https://bitcointalk.org/index.php?topic=28402.0
Here's a more direct walkthrough of the installation (for windows 7 at least): http://rdmsnippets.com/tag/install-block-erupter-on-windows-7/ which will likely be helpful.
I use BitMinter and just plugged two (one at a time) block erupters into my laptop, once they were installed properly, I did a port scan in BitMinter and was up and running with no issues, only took but a minute or two.
