I have a raspberry pi 2 Model B and I want to disable the power to ethernet and USB hub port, I try using hub ctrl. c command, and it doesn't work.
Is this happening because of the limitation of the hardware? Will this be working on Raspberry Pi 3 Model B?
Actually, I want to control the USB port. Since there are four USB ports on my raspberry pi 2 model B, I want to know If it is possible to turn off the power of USB ports with software, not with hardware.
