You already adjusted the configuration to meet your basic needs with the help of basic config? Good. If your device has USB ports, here you see how to put them to good use.
Some routers might have difficulties providing full USB power output.
On some routers, it is possible to turn USB power on and off using GPIO, like this:
echo 1 > /sys/class/gpio/gpioN/value
echo 0 > /sys/class/gpio/gpioN/value
Get current state:
N should be replaced with pin number, which depends on router model. Here are some known pin numbers:
|TP-Link TL-WDR3600||21, 22|
|TP-Link TL-WDR4300||21, 22|
If your model is not listed, you may try to find
N by trial and error. For some
N, the directory
/sys/class/gpio/gpioN might not exist, in this case it can be created like this:
echo N > /sys/class/gpio/export
