I've just compiled rock64_defconfig from master and USB does ineed
work, I checked USB3 and USB2 pendrives and keyboard but...

Only 1 USB port seems to work - bottom USB2.0. I remember there
were some issues with USB3 at the time I did the port, but cannot
remember why the upper USB2 does not work, maybe some regulator is
not enabled in default dtb?

Try different USB port and see if that works.
