Ah, is there a reason why a USB hub wouldn't work?
@kosame that would probably work (and if powered, probably work better than one of the Pi's ports) but I'm trying to keep everything compact and mounted to the printer.
This is part of what led me to using the A, because it's smaller, but now it's just making things more complicated :)
Also, idk why I thought you connected monitors using USB. I should sleep.
@kosame Oh, I mean I have no additional USB port in which to plug a webcam into (the only port is in use connecting to the printer).
