I set up Octoprint 1.4 and GPX plugin 2.6.3 on my RPi 2B to use with my Makerbot Replicator 2. However, my RPi does not seem to recognize the printer.
The best I have is this, but I suspect that the Pi is just not registering the Replicator as a USB device. Has anyone had this problem?

EDIT: OctoPi version 0.17.0, OctoPrint version 1.4.0, installed this morning. I'm at a loss, because googling didn't come up with anything useful
