I'm using a beaglebone Black, debian. 4.1.15-ti-rt-43. I'm trying to achieve the same thing. -- accessing my external storage SD card (in the BBB which is booting off emmc). I have log files which I save to the SD card and I want to access them by connecting my beaglebone to the computer (instead of taking out the SD card, putting it into a reader and then into my computer).
However, /usr/bin/g-ether-load.sh and /lib/systemd/system/storage-gadget-init.service don't exist where it's said to in this answer, so I don't know how to proceed.
