My ASICMINER USB Erupter showed up about an hour ago.
Been playing with the Icarus timing settings still not quite got it right yet.

Obviously yes I'm getting around 300MH/s out of it.

Currently best settings are for anyone wondering while I sort it out:
 --icarus-options 115200:2:1 --icarus-timing short
