The former Hearts winger has been put straight into the squad for tonight's Premiership clash with bottom club Motherwell after signing a short-term deal.
Driver spent two years with MLS side Houston Dynamo and believes he has returned a stronger, fitter and better player.
The 27-year-old said: "I have really enjoyed the short time I have been here already. I can see it's a really good club, it's run well.
"I have enjoyed the training and it's on me to go out and earn anything I can get. I have enjoyed it so far and hopefully I can show what I can do.
"I went to America and you are kind of out of sight out of mind. But I really enjoyed it and I improved as a player when I was over there.
"The last couple of years at Hearts were pretty tough and I maybe didn't reach the level I ought to but I have come back now with renewed vigour and I really want to go and prove a point."
