Hey,
It won't let me post a message on the clarification board, so I am going to write it here.
Can you provide additional information on your setup?
Stuff like what operating system are you using, what mining software, if you are using any USB hubs, what steps have you already done (what specific driver did you install?).
I am currently running a mining setup with linux/usb hub/one block erupter/bfgminer for bitcoins and have a knack for technology, so I should be able to help you.
Thanks.
P.S.: Not sure if anyone mentioned it to you, but if you are in this for profit (as opposed to for fun/learning), you will barely make any money using just block erupters because the difficulty is sky high.
Here's a calculator for mining profit with one USB block erupter: [login to view URL]
Adding a bunch won't make a huge difference either (play with the values).
