Troubleshooting • Re: USB port on RPI Zero 2 W not detecting any devices

@OP:
Can you confirm that you are using the correct USB port on the zero2w. The data port is the one nearest the mini HDMI port.

Definitely using thge USB data port (closest to HDMI)

Have you tested with a different microUSB B male to USB A female adapter? Your current one may be the point of failure.

Yes, I tried a different OTG microUSB B male to USB A female adapter, and also replaced the USB cable from the powered hub that connects to the USB A female adapter

Can you try after adding the following to your config.txt. This isn't recommended long term as it will impact performance. It should use a different driver and force host only mode on the controller.

I added:

dtoverly=dwc2,dr_mode=host

to the /boot/firmware/config.txt in the "[all]" section, however I changed "dtoverly" to "dtoverlay" because I was assuming it was a typo. I rebooted and it did not change the symptoms and I have since commented it back out:

[all]
# troubleshoot non-working USB port
# dtoverlay=dwc2,dr_mode=host
# end troubleshoot section

Regards,

Steve
