The instructions for setting up a direct-connect RPi Zero over USB have me
dtoverlay=dwc2on a new line to `config.txt', and
Are these settings specific to or limited to the RPi Zero and/or to a direct USB connection? That is, could I use an SD card with these settings generally on on my RPi's regardless of how I connect to them. For example, could I use these settings without side effects on an RPi 2 or 3 that I connect to using the Ethernet port?
