If you edited the rc.local file in /etc please remove the line from rc.local and issue this command as root:

cd  /etc/systemd/system/
sudo  systemctl  enable  usb_gpio_on.service

Thanks!  Smile
It worked fine for me on Stock Debian LXDE (Rock64 SDCard) Build 20170809. This is a production Rock64 with 4GB that I received recently. Checked successfully that the directory gpio2 exists in /sys/class/gpio/.

Has worked three times so far:
- After reboot finishing the fix.
- After Shutdown and full power down. Starting from applying power to the Rock64.
- After Shutdown and pressing the Power button on the board.
3 for 3 is the best I've seen so far. 

Followed directions carefully and had no problems. Linux is still not my comfort zone. I've lived mainly in Windows going all the way back to MS-DOS days.

Next problem is to fix is the changing MAC address after reboot. I have a gazillion entries in my router thanks to this problem.
