Note: this is not the latest version of cgminer, at the time of this writing, the current version (3.3.1) has issues communicating with Block Erupter USB on Raspbian
FYI, I also experienced issues with Block Erupter USB's on Raspbain. However I was successful at building and running cgminer from git (3.3.1) after dist-upgrading Raspbain from wheesy to jessie.
