My Ubuntu 14.04 laptop connects to my Galaxy S3 with no problem using a USB cable. When I connect my Galaxy Note Pro with it's special USB cable the icon shows up in the launcher, but when I try to open it I get
Unable to mount SAMSUNG Android
Unable to open MTP device '[usb:004,011]'
Both are running Android 4.4.2. What do I have to do to get Ubuntu 14.04 to mount my tablet?
