Hi,

I have an AR300M and I search a way to switch the USB-Port in a script on/off

Thanx Asado

find the correct file for controlling the USB:

ls /sys/class/leds/usbpow

Then control the USB power using it

echo 0 > /sys/class/leds/…usbpow…/brightness

echo 1 > /sys/class/leds/…usbpow…/brightness

Wow, thank you very much.

It works great

OFF

echo 0 > /sys/devices/platform/leds-gpio/leds/gl-ar300m:usbpow/brightness

ON

echo 1 > /sys/devices/platform/leds-gpio/leds/gl-ar300m:usbpow/brightness
