My A818 is already supported as a MTP device in Hardy. Just try to plug
it in and launch Rhythmbox.
However, I would feel very angry to see that Ubuntu used to support it as a
mass-storage device, but would prefer to use a proprietary drm-friendly
protocol with the following drawbacks :
- it would not be possible to feed the device with a simple drag & drop
- it would be mandatory to use a special software (e.g. supporting MTP, like
Rhythmbox) to load music on the player
- it would be impossible to load videos nor photos on the device, as Rhythmbox
does not support video or photographic content
The only question to ask is : what has changed in HAL fdi rules (or in
whatever underlying layer located between the kernel and HAL) between
Gutsy and Hardy that just prevent HAL from exposing the device's FAT32
volume to other programs.
gnome-mount - doesn't see the volume because it is not exposed by HAL
HAL - detects the device, probe for a volume, find it, but does not create
volume information in his tree (see following debug log)
Kernel - see the volume and is able to manually mount it using mount or pmount
