Ubuntu – How to get a Dane-Elec mp3/mp4 player working

.mp4hardwaremp3mp3-playermusic

My MP3/MP4 does not plug-in and play and therefore I can not transfer any file to the MP3/MP4 dane-elec music my touch or only dane-elec with 8 gb in memory and perhapses model zt1 with radio,..and microsdhc card slot

following the above link the mp3/mp4 is there and it is MP3 Player: TOUCH MY MUSIC and the complete information is on this site http://www.danedigital.com/8-Music-Media-Players/2-music-touch.html as the Technical Specifications

MP3 Player: TOUCH MY MUSIC The Mp4 player has a very classy. It allows its users to play music and view photos and video. His fluent interface, its touch-pad, his radio and RDS Micro SDHC reader makes him a very complete device will become the ideal musical companion.

ubuntu i am with is ubuntu 11.10 kernel 3.0.0-14-generic the latest

I tried to install many applications but nothing worked.

With disk utility I can see that Ubuntu can recognize something, that as a peripheral device named rockchip usbdisk user and rockchip usbdisk sd,

and i can plug and play other devices, and only this mp3/mp4 do not connect to the computer with ubuntu and the device as no problem working disconnected to computer

I try to see if work on Windows and it does! I can see the device and transfer files to the MP3/MP4 dane-elec folder device and use FAT32. So why can not do on Ubuntu!?

What can I do and why does not work on Ubuntu? What is wrong with it?

Best Answer

I'm not sure if I can help get this working, but this will help troubleshoot the issue.

  1. Unplug the device
  2. Start a terminal (search for "terminal" in the Dash)
  3. Type tail -f /var/log/kern.log into the terminal and press return.
  4. Plug in your Dane-elec MP3 player.
