# Disable USB Port on Raspberrry Pi 3

I recently bought a Raspberry Pi 3. But unfortunately the first one I got was damaged. We managed to get it going but one USB port was rendered useless. Now I want to know whether it would cut down power consumption by disabling the use of the USB(if so how?) or does it do the same thing just tearing the port off? By the way I am running Raspbian.

• Just a note: On at least RPi3b power of all [USB-ports] and [Ethernet+WiFi] can be switched separately. There is a tool called uhubctl doing this using libusb (port 1 for Ethernet+Wifi, port 2 for USB). – Suuuehgi Oct 3 '17 at 6:30
