USB help with Original Moto Droid

I have recently installed the gingerbread rom on my droid. I have had it running for about 2 weeks. Everything was working fine until recently. I connected my phone to my computer via the usb cable and it did not detect it. Not on the pc and not on my phone. The usb icon didn't even show up in the top pulldown panel. I have tried restoring it to a backup I made before I updated the to the current rom. I have tried for days now. I can't even get it to show on rsd lite. I don't know what to do. The only time it will detect the usb is when I plug it into my wall charger. I am on rom GPA13. I am about to update to GPA14 and see if that fixes the problem. If anyone can help me, that would be amazing since I have run out of energy and am just about to give up on this phone. Also, I have tried it on other computers as well. Still nothing. I have plugged in my friends G2 phone and it reads it without a hiccup. I am running Windows 7 64 bit.
