Update: I did a couple things pertaining to enumerating my TTYxxxx & USB devices, it made no diff, but then I did two things: shutdown -h now & moved usb to the physical port it was in when it was working before || powered it back up and now it's talking to the Ultimeter. TTYUSB0 stuff is a mystery, but it's working and I'm going to be careful to not ever change the physical port again, or even unplug it while it's running. #superstitious
