GPIO map for enabling usb on GL-B2200

quantonian · 2024-09-22T18:52:09.597Z

Hello, I am trying to determine the GPIO number to enable usb on the Velica GL-B2200.

The base is 412 for this router:

root@OpenWrt:/sys/class/gpio/gpiochip412# cat base
412

The docs define various gpio values but not usb:
https://docs.gl-inet.com/router/en/3/specification/gl-b2200/

I also have the qcom-ipq4019-gl-b2200.dts file that shows various gpio valued but usb is not defined.

Any help is appreciated!

root@OpenWrt:/sys/kernel/debug# cat gpio

There is not USB interface for the B2200 casing

hecatae · 2024-09-24T09:52:26.792Z

By this do you mean the USB C power input is power only and cannot be used for data?

bruce · 2024-09-24T09:53:55.108Z

yep, that is right.
