Usb Power control

Good morning everyone.
On my flint2, as long as I kept the original firmware, I could control the USB power (/sys/class/gpio/usb_power/value).

Now I've switched to openwrt and can't find the directory anymore.

Do you know how I can fix this?

Thanks.

Hello,

Vanilla OpenWRT firmware does not support controlling USB power, probably not be within our support range. Please consult in the OpenWRT community.

You can use v4.8.2-op24 firmware for Flint2.
