Computer won't recognize iPad 1

Alright, so I plug my iPad 1 in to put some music on and neither the iPad nor the computer recognize it. I had recently updated my compputer so I restarted it. That when it booted up it still didn't work so I thought it was the cord. I tried 4 different cords, including the one that came with the iPad and still nothing. I tried all the USB ports and even tried an external USB port. The computer recognized the USB port but still not the iPad. I just synched my iPod touch so I know its not the computer, and I tried it on my Mac. The charging on my iPad still works, it just says Not Charging, however this problem has been going on for awhile. I reset the iPad and the settings and that still didn't work. Any help?
