USB cable doesn't work (Canon 5D Mark II)

Hi,

I accidentally tripped over my usb cable when it was connected to the camera, and now it doesn't work. I tried a different usb cable that I had in the house that has the same end, and it doesn't work either.. Does that mean that I messed up the camera port? or do I need a special usb cable for this camera?

I have a Canon 5D Mark II

Thank you for your help!
