Great instructions. Just found out my 2 year old 7D has shutter count of 35389. I'm happy with that.
Also, I had trouble recognising my camera at first. Error (-105: 'Unknown model')
But I guessed my external hard drive was confusing gphoto2. After disconnecting it and leaving only my 7D connected, I was able to connect to my camera and determine it's shutter count.
