I’m having trouble getting a P1 on a custom PCB to talk to my computer via USB. I have the Particle driver installed and have had no issues with the Core or Photon. However, with serial enabled, the P1 does not show up as a device on my Windows computer.
Is there a way to troubleshoot this? I have D+ and D- connected to pins 61 and 62, with a 22ohm resistor in between each one and the USB pin. Both show positive 1.85V, but I’m not sure what to make of it.
Thanks for looking!
