here are four USB miners that I know that mines Bitcoin the Block erupter, Newpac, Compac F, and Antminer U1 USB miner.
Ya left out 2 of Sidehacks other sticks: His original Compac and the TwoPac that used the S3 chips. The Compac had 1 chip and the TwoPac had <drum roll please> 2 chips.
Und ja, that looks to be a Block Erupter from ASIC miner. I believe it used a chip from Bitfury.
Back in the day they were pretty good but these days even compared to an old Compac it is horribly inefficient. Current best stick made is Sidehack's Compac-F that does over 300GHs while pulling less than 15watts.
