Add Zero 3 USB Host Mode #320

Closed dfloer closed 1 month ago

dfloer commented 1 month ago

This dts enables the OTG port on the Zero 3 to be used in USB host mode. It was based on rk3568-dwc3-host.dts and rk3588-dwc3-otg.dts. Tested working on a Zero 3W with a variety of "USB OTG adapters" and passthrough hubs.

Do you mean rk3568-dwc3-host.dts doesn't work on 3W? It should be provided as an option in rsetup.

dfloer commented 1 month ago

Correct, I needed the usb-mode-switch; line for it to work on my device.

Radxa-Alvin commented 1 month ago

We tested that rk3568-dwc3-host.dts can be used normally. Can you tell me what device you are using？

dfloer commented 1 month ago

I just tried it again on a Zero 3W, and it did work for me. I guess I'll close this PR as it's working. Sorry about that.

Using an "OTG Power Splitter" type device with a flash key:
