Comment 18 for bug 306410

Thank you for that extra information! However, are you sure that running the mtp-detect command as root -- 'sudo mtp-detect' -- doesn't give a longer output?

You could also try to get some output with the latest version of libmtp8. I've uploaded the 1.0.1 version, the first to include support for your player, to my PPA at <https://launchpad.net/~qense/+archive/ppa>. If you'd be able to give us the compete output of 'sudo mtp-detect' with that version, we'd be most grateful. However, please bear in mind that this version still has some issue with the rest of the system; Banshee's MTP support will stop working with this version and Rhythmbox' will lag and be less stable. The problems will probably be worse for pre-Karmic releases.
