  Hi,

   

  I saw some other people having this problem too, was there ever a fix for this? The power works on the USB ports of my x306, but not the data, so I can't get anything to connect via USB on my Pi Zero. Here's the troubleshooting steps I've taken:

  Tried Pi Zero 2 W, Pi Zero W, Pi Zero 1.3: none work

  Tried micro usb hub without x306: works

  Tried adding "dtoverlay=dwc2,dr_mode=host" to config.txt : does not work

  Confirmed pogo pins are making contact with test pads

  Ferrite ring

   

  None of these seem to work, is there something I'm missing? Would love any help, thanks so much!

  Have you tried a different USB OTG cable or adapter between the Pi and the x306? Sometimes the data lines don’t get picked up if the cable is charge-only. Also worth checking if the overlay is being loaded correctly in dmesg after boot — that might help confirm whether the Pi is actually switching into host mode.
