Rizka R.

There are Server way you can enable or disable USB port. We all know common way to enable or disable USB port from bios setting.

But Here i am sharing some ways to enable disable USB Port by Terminal.

Method 1 :-

1. Open Terminal (Ctr + Alt + T)
2. Type  " chmod 000 /media/ " (FOR DISABLE USB)
3.To Enable Type " chmod 777 /media/"  (FOR ENABLE USB)

The above chmod is nothing but change mode which is a part of unix/linux code mainly used for read or write permission that can be represented by numbers.

Method 2 :-
     In My Second Method , Suppose you want disable and enable port 3 and device 2.(you can get the information from lsusb -t)

1. Open Terminal (Ctr + Alt + T)
2. Here i am turn off port number 3 and 2 device.Just Type in Terminal

          " echo '3-2' |sudo tee /sys/bus/usb/drivers/usb/unbind"
