The Pine H64 board features an USB 3.0 type A port, which works just fine. Enable the controller and USB PHY in the .dts to make it usable.

Exactly the same patch was already proposed by Icenowy. In short, PHY is powered by internal power and doesn't need phy-supply property. It's connector that needs power supply. One of her latest attempts can be found here: https://lore.kernel.org/patchwork/cover/1058917/ Best regards, Jernej
