The instructions for setting up a direct-connect RPi Zero over USB have me

  • add dtoverlay=dwc2 on a new line to `config.txt', and
  • insert modules-load=dwc2,... in cmdline.txt.

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?

I use those settings on all my SD cards and swap those cards merrily between Pi Zero, Pi B+ and Pi 2 with no side effects.

  • All the linked-to settings, or just the dwc2 settings above? – orome Jul 18 '16 at 15:40
  • The link in the OP only outlines these 2 settings, as I read it..? Which other settings are you concerned about ? – KennetRunner Jul 18 '16 at 15:56
  • Yes, the OP (me) just asked about those, I wanted to confirm that "those" didn't refer to the link as well. – orome Jul 18 '16 at 16:00
