B-L072Z-LRWAN1 board not recognized through USB on Ubuntu 18.04.3

I just received my B-L072Z-LRWAN1 board in the mail. I want to use it with Arduino, but when I plug it in to my Ubuntu computer it is not recognized at all. Nothing shows up through 'dmesg' command, nothing shows up through 'lsusb' command.

If the OS can't see it, clearly the Arduino IDE can't see it.

Any ideas what is going wrong? (I've also tried multiple USB cables, and Ubuntu computers)

There are two USB ports on the PCB, which one are you trying to use? Make sure you are connecting to ST-Link/V2-1 port. Also read the "Power Supply" section of the user manual, ST-Link's USB connection's power might be not enough to power up the whole board.
