tp-link tl703n usb power on/off via gpio8

to disable/enable power to the tp-link's usb port just set /sys/class/gpio/gpio8/value to 0 (zero) for power off and to 1 (one) for power on. example on the shell: echo 0 > /sys/class/gpio/gpio8/value

that works very well when used to "command" a usb controlled master/slave multi-way power connector

in my case I use this to power on or off an equinox tizi that is running on the power of the tp-link device. that way I can have the tizi upstairs where there is a dtt signal and switch it on and off from my office in the cellar.

I'm very annoyed by the fact the tp-link now comes with a firmware that cannot be easily changed to openwrt. I will stick to the more versatile alfa networks ap121u (http://www.amazon.de/dp/B00CZ81428 in the future. it also can run just on usb-power assuming you use the right cable: usb to 5,5mm/2,1mm hollow plug
