Power down USB ports

[Lissanro]

I am personally use this tool to power down and then turn on USB ports:

USB Power control

Hi, On Nano, please download/extract the attachment and follow the steps: Copy realtek_hub_power_cycle.c to Jetson Nano $ sudo apt-get install libusb-1.0-0-dev $ gcc -o power_cycle realtek_hub_power_cycle.c -lusb-1.0 $ sudo ./power_cycle realtek_hub_power_cycle.zip (653 Bytes)

It has very short source code, the most important part is in function power_cycle(). It has the code split in two parts, one marked as “vendor command enable” (I think it powers down ports) and “vendor command disable” (I think it turns them back on). You can try to split it into two functions to turn USB ports on and off.
