Hey, I just got my Creative Zen Vison: M 60GB player working.
First, make sure it is plugged into a USB port.
Then, open a terminal, and type "lsusb"
The player should show up in that list as a Creative product.
Then, type "mtp-detect"
If it isn't detected with that, type "sudo apt-get install mtp-tools"
This should make it work...I haven't tried it in Amarok yet, but using Gnomad2, it works perfectly.
If you are in Ubuntu, you can probably search for gnomad in the Synaptic Package Manager, or go to this link
http://ubuntuforums.org/showthread.php?t=199250 for install instructions.
Hope this helps, this is what I had to do to get it operational.
