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?

Are you asking about support for transferring files to a specific device? MP3 and MP4 files should be playable by Ubuntu. –  fader Jan 4 '12 at 1:50
    
Can you edit your question and add what model of mp3/mp4 player you have? –  Jorge Castro Jan 4 '12 at 2:11
    
yes, to a device , hardware.. and i can play mp3 and mp4 file that is not the issue. –  user40432 Jan 4 '12 at 5:12
    
i am not sure if i am asking to the question about the model of the device but saying it all is a mp3/mp4 device named dane-elec music my touch or only dane-elec with 8 gb in memory and perhapses model zt1 –  user40432 Jan 4 '12 at 5:19
    
can anybody explain to me why is not working the mp3/mp4 ? –  user40432 Jan 4 '12 at 16:07

1 Answer 1

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.
  5. Post the results into your question

You should also run sudo lsusb and sudo lsusb -v while the device is plugged in and post the results of that into your question too.

From the Linux USB FAQ : http://www.linux-usb.org/FAQ.html#ts6, you might want to try forcing the device to only connect at USB1.1 speeds. In a terminal, run the command rmmod ehci-hcd then reconnect your device.

That FAQ also suggests that some motherboards will benefit from being started with "pci-noacpi" or "acpi=off" as boot option. Another suggested a "noapic" option. These are GRUB options - out with my expertise, but perhaps this site links to other answers that might help.

rmmod ehci-hcd send this error, ERROR: Module ehci_hcd does not exist in /proc/modules –  user40432 Jan 5 '12 at 23:40
    
how i change boot options to one of those –  user40432 Jan 5 '12 at 23:49
    
Did you try that command with sudo? –  Scaine Jan 6 '12 at 1:47
    
yes and have give the same error ERROR: Module ehci_hcd does not exist in /proc/modules –  user40432 Jan 6 '12 at 23:50
    
does anybody as another suggestion? –  user40432 Jan 7 '12 at 0:09
