@nylonatathep Very good! This works as well for the original "red PCB"-Version (and should become the default when compiling armbian within a day or two).
 

USB on the back does not work => Information:
 
I compiled Armbian (Bionic, 5.5.0rc2) and tested it on my r69 h2 ver. 1.3 blue PCB with nothing special.
Everything works fine except the USB on the back.
After some investigation I checked the dtb file and there is the back-USB port configured as OTG.
I dont' know if is this a bug or a feature but if you want to use both USB you have ti change the dtb file.
After decompile change line 322 in dtb from "otg" to "host", compile it again and replace the orginal file in /boot
I added the corrected dts and the compiled dtb file for Kernel 5.5.0rc2.

For future reference:
cd /boot/dtb sudo cp sun8i-h2-plus-nanopi-duo.dtb sun8i-h2-plus-nanopi-duo.dtb.old sudo dtc -@ -I dtb -O dts -o sun8i-h2-plus-nanopi-duo.dts sun8i-h2-plus-nanopi-duo.dtb sudo nano sun8i-h2-plus-nanopi-duo.dts (remove r_gpio_keys section) sudo dtc -@ -I dts -O dtb -o sun8i-h2-plus-nanopi-duo.dtb sun8i-h2-plus-nanopi-duo.dts reboot

Users wanting to use debian builds with NetworkManager/wpa_supplicant should add the following lines to /etc/NetworkManager/NetworkManager.conf:
[device] wifi.scan-rand-mac-address=no Ubuntu builds (bionic, focal) already contain these lines.
 
This seems to solve the current issue on systems with the xradio wifi chip (opi zero, nanopi duo etc.)
