What This PR Changes

  • Added short tutorial on how force USB host mode on the UNO Q, while being powered externally.
  • Issue occurs as the VUSB path is not enabled when powered via 5V/VIN
  • Patch has since been added that will run a short script on launch automatically, granted that GND and VOL_DOWN is shorted as described in this tutorial.

I still don't believe this "by bridging two pins" is necessary in the description.
feels like you're selling me how easy something is, and it's not necessary
