cgminer compile question

[studysession]

I bought a used USB miner off ebay - when doing the './configure --enable-something....'

How do I know which one to choose?
How do I know if it is using my USB miner when finished?
Any other --options should I include?

I am running a RaspberryPi2 with Raspbian

I used the --enable-icarus because I found someone posted that in a series of searching I was doing. I am mining however none of the lights on my USB miner is on or blinking however when you touch it - it's very hot so I am going to get a USB fan for it.

This was what I bought -

Thanks -
Keith

The --enable-Icarus is correct for Block Erupters.

Also there is a CGMiner thread so post there.
