RPI3 with MC7455 can't see /dev/ttyUSB0 etc

IoT Modules MC/EM Series

I’m trying to connect a MC7455 to a Raspberry Pi 3B via USB. I followed the steps in the Linux QMI SDK Application Developers Guide to download the latest SierraLinuxQMI drivers. I built and installed the drivers (GobiSerial and GobiNet), blacklisted the recommended items and the bluetooth items, and removed Modem Manager. It seems that GobiSerial and GobiNet are installed, but I don’t see any of the devices that should be created. Am I missing something that would stop the /dev/ttyUSB devices from being created. Here are a few samples of my system status:

I can only post one image per post since I’m new, so I’ll post them separately.

Thanks
