Because I'm not at my mother's I verified EACH TIME if the scan is properly connected with commands : lsusb and it appears always at the right USB-Hub.
The error isn't at my mother's side ! but because hplip isn't updated with the system and kernel. You are working with a 2 years old system (1.19.6) and not with the actual system (1.20.4) and as far as the kernel is concerned you are working with the Linux 4.4.0-138-generic instead of Linux 4.4.0-148-generic
Hi Santhosh !

Please update your system and try once again !
