Enable or Disable USB in Linux

To Enable / Disable USB 


To really disable and enable USB, lets say port 3 and device 2 (you can get the information from lsusb -t)
    

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

  2. echo '3-2' |sudo tee /sys/bus/usb/drivers/usb/bind
    3.


Another Method
chmod 000 /media/  here is where device is mounted hence make it 000 -> not able to read or write files
chmod 777 /media/  extact opposite to above i.e able to read and write the files
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.
