Hi all, thanks for feedback so far. I got a bit of a lightbulb and am now using BSS138 MOSFETs with a Multiplexer to do this, and I think it's correctly setup. :) I must say that this solution ended up quite nice. Essentially power from USB connector #2 will have priority if connected, but what is cool is that both USB connectors will power a led to indicate which one is active so that will always be shown. Then the the MOSFETs will set the multiplexer to choose which lines that are active from either USB connector. |

Also, shoutout to https://www.falstad.com/circuit/circuitjs.html for helping out with experimenting with n-MOSFETs! :) |
