Once in a blue moon, my ipod (160 GB) will show up in rhythmbox on my ubuntu 12.04 laptop when I plug it it, but most of the time nothing happens.
It shows up when I do fdisk -l, but when I try to mount it by sudo mount /dev/sdd1 /media/ipod, where sdd1 reflects the output of fdisk, and where /media/ipod is a directory I created, mount says that either it is already mounted, or that the directory is busy.
Doing sudo umount /dev/sdd1 gives that the device is not mounted. But doing sudo /usr/bin/udisks --mount /dev/sde1 /media/ipod gives that it is mounted. I am also able to see that the device is connected by doing sudo blkid. Asking rhythmbox to 'search for new devices' appears to have no effect.
