I took the latest linux v5.3-rc4 and added some basic ehci0 and
ohci0 nodes. I built the dtb with musl-cross-make and by running
make dtbs in the linux source tree:

This is how the nodes are in the pinebook dts and similar to an
armbian patch:
https://github.com/armbian/build/blob/master/patch/kernel/sunxi-dev/xxx-teres-fixed.patch
Here is my resulting dmesg and boot log. External usb ports were
unresponsive, inserting and removing a flash drive showed nothing
in dmesg and the light on the flash drive did not turn on. Also,
the usb wifi dongle was not recognized, and no keyboard in dmesg:
