For no clear reason, my Makerbot stopped being recognized at all by the computer. I can't see it in any printing software or even in Devices and Printers. It's normally connected through USB. Any suggestions are welcome. Below are the troubleshooting steps I've already tried.

PRINTER: Makerbot Replicator 2
COMPUTER: Windows 7

TRIED:
- Checking physical plug connections (unplugging, replugging)
- Plugging into different computer
- Using a different USB cable
- Using different USB ports
- Restarting printer
- Restarting computer
- Using different software (tried both Makerbot Desktop and ReplicatorG)
- Restarting Makerbot background service
- Reinstalling Makerbot Desktop software

The printer functions fine if I try to print from SD. As far as I can tell, both the printer and the computer are operating fine. There is just something going on with the connection that I can't figure out.
