Yes. Freshers get fired too. It's important for you to remember that at the end of the day you are a resource (albeit, a human one perhaps). Initial teething problems are fine. But don't get comfortable with them. Take every failure as a challenge. If you feel bad that you've been relegated to menial tasks, the only way for you to stick it to them is by executing even the most menial tasks meticulously. Then, when you do get a proper task don't let your self down (Eminem lose yourself style). It's not rocket science (even in the literal sense).
