Greeting BTC Community!!

I am trying to mine on my new USB Block Erupted but having some difficulty getting started.  After searching the forum for a bit I figure it's time to ask for some help.

I have BFGMiner 3.1.1 running on Ubuntu 12.04 64bit

The output of bfgminer -D -T -d? is

Code:

The command string I've been using to start bfgminer is

Code:
bfgminer -o stratum.btcguild.com:3333 -O MyUserName:MyPassword--rotate 2 --temp-target 70 --temp-overheat 72 --temp-cutoff 74 --auto-fan --auto-gpu

since it seems that the computer recognizes the hardware, and it is supported in BFGMiner I conclude that I'm likely doing something wrong when starting the miner.  Any help would be greatly appreciated.

I believe you need some specific Icarus arguments in there and maybe a com argument in there in order to tell BFGMiner that you are using an Icarus device and what com port to use.

Squiggly letters, written really fast, with a couple of dots for good measure.
