Are you signed up with a mining pool? I would recommend Slush's if you have not.
After you sign up with Slush you should go to the FAQ and it will give you what you need to connect. (It should be something like:
BFGMiner -o stratum+tcp://stratum.bitcoin.cz:3333 -u (your username) -p (password) --disable-gpu (to disable your GPU if wanted) -G -S erupter:all )

keep in mind that 1 ASICMiner will take you over a year to earn 1 btc.
