Borrowed from the Armbian forum, this snippet makes it possible to force the USB interface on a Banana Pi CM4 to be operated in host mode, which turns out to be necessary when said Banana Pi CM4 is mounted on a Turing Pi 2 cluster board using one of their CM4 adapters.

Save this to meson-g12b-bananapi-cm4-waveshare-usb.dts, then (as root) run armbian-add-overlay meson-g12b-bananapi-cm4-waveshare-usb.dts, and reboot. Suddenly, you should have a working USB port that you can attach exciting devices to, like keyboards!
