The Orange Pi Zero 2 W currently only support one USB port in host mode (the one further from the edge of the board). If you want to be able to use the one near the edge (USB0) you can do so by modifying the system device tree.

Decompile device tree, into user’s home directory:

`dtc -I dtb -O dts -o sun50i-h618-orangepi-zero2w.dts /boot/dtb/allwinner/sun50i-h618-orangepi-zero2w.dtb`

Modify `sun50i-h618-orangepi-zero2w.dts`

```auto
...
usb@5100000 {
  ...
  status="disabled"
  dr_mode="host"
  ...
}

usb@5101400 {
  ...
  status = "okay";
  ...
};

usb@5101000 {
  ...
  status = "okay";
  ...
};
...

```

Backup the existing system device tree:

`sudo cp /boot/dtb/allwinner/sun50i-h618-orangepi-zero2w.dtb /boot/dtb/allwinner/sun50i-h618-orangepi-zero2w.dtb.bak`

Compile the modified device tree from user’s home directory into the system location:

`sudo dtc -O dtb -o /boot/dtb/allwinner/sun50i-h618-orangepi-zero2w.dtb sun50i-h618-orangepi-zero2w.dts`

Reboot:

`sudo reboot`

I’m trying to turn this into a device tree overlay so the configuration will be easier and safer.

Ok, the much safer way to set this up is using overlays. Don’t use the method above, but rather try this method first:

Create ~/sun50i-h616-usb0-host.dts

```auto
/dts-v1/;
/plugin/;

/ {
    compatible = "xunlong,orangepi-zero2w", "allwinner,sun50i-h618";

    fragment@0 {
        target = <&usbotg>;
        __overlay__ {
            dr_mode = "host";
            status = "okay";
        };
    };

    fragment@1 {
        target = <&usbphy>;
        __overlay__ {
            status = "okay";
        };
    };

    fragment@2 {
        target = <&ehci0>;
        __overlay__ {
            status = "okay";
        };
    };

    fragment@3 {
        target = <&ohci0>;
        __overlay__ {
            status = "okay";
        };
    };
};

```

Compile the overlay:

```auto
dtc -@ -I dts -O dtb -o ~/sun50i-h616-usb0-host.dtbo ~/sun50i-h616-usb0-host.dts

```

Copy it to the system directory:

```auto
sudo cp ~/sun50i-h616-usb0-host.dtbo /boot/dtb/allwinner/overlay/

```

Enable it in the DietPi environment by modyfing `/boot/dietpiEnv.txt`

```auto
sudo vim /boot/dietpiEnv.txt

```

And add these lines to it:

```auto
overlay_prefix=sun50i-h616
overlays=usb0-host

```

Save and reboot.
