Host USB Ethernet not working

[then...@gmail.com]

All.

Just booted my PocketBeagle using the image 'bone-debian-9.1-iot-armhf-2017-09-21-4gb.img'. I downloaded the image, unpacked it and used dd to copy it to a micro-SD card (old school, don't want to use the GUI tool, whatever it's called). The PocketBeagle boots, and from my Debian 8 host, I can log in using the serial terminal created when I plug the PocketBeagle into the host USB port. So, I can confirm that the Beagle is booted and seems to be running correctly. I logged in as root and created a new user:

The problem I'm having is with the 'virtual ethernet' that is supposed to get created on my host computer. After the Beagle boots, I see two network devices show up on my Debian host computer:

# /sbin/ifconfig

However, there seems to be nothing I can do to make those two devices work. I've tried assigning IPs using dhclient. I've paddled around with Network Manager, but I'm never really sure what it is actually doing. I see two drivers report in dmesg when I plug the Beagle into the host USB port:

From above, it looks like I should be seeing eth1 & eth2 devices, but instead I see those two oddly named devices that can't seem to do anything. The Beagle shows up as a mass storage device, and I've run the script in the Linux drivers part of the filesystem it provides, but all it does is update a few udev rules that only seem to be related to the mass storage part of the USB interface. I've tried mounting and unmounting the mass storage part of the USB interface, and nothing seems to make a difference.

So, I'm looking for suggestions about how to make my Pocket Beagle into a virtual ethernet device. I would like to be able to mount the Beagle as an NFS share or have the Beagle mount my Debian host computer as a shared filesystem, so I can easily test software written for the Beagle, but developed on the host computer. Some time ago, I was able to easily make the virtual ethernet work on a BBB, using the same host computer, but it may have been a different host OS. I don't have access to the BBB for comparative testing any more.
