Kali airodump-ng error ( ioctl(SIOSCISWMODE) failed: Device or resource busy )

                                             I was just using Kali and had a problem with airodump command . it showed error and i was unable to put my wireless card in monitor mode .. error is below

                     Then i used another way to put my card in Monitor mode             
  
        First of all confirm your wireless card name by typing command= iwconfig

           then         sudo ifconfig wlan2 down   .. This will turn your card off
                           
                  After this put your card into monitor mode by typing = sudo iwconfig wlan2 mode monitor

         then again turn on your card by typing= sudo ifconfig wlan2 up

               To check your mode type sudo iwconfig wlan2
