USB Port jarred / How can I open the case?

I am having trouble finding the exact model I'm using online, but my passport recently fell from my bed while attached, and this caused the usb port in the back to... screw up. Now, the computer will not detect it when plugged in. The plug doesn't seem to be able to go in all the way anymore, or sit securely in. It wobbles and slips out very easily.
