Unable to get MP3player to be detected.

[jim_naisium]

Hi,

I have a Coby MP826-8G USB MP3 player that when plugged into my Windows XP machine is detected, installs, and lets you drag files into it and then plays them without any problems.

When I plug it into my Ubuntu Linux v10.04 PC (completely different PC) the USB icon on the MP3 player lights up flashes a couple of times, then it starts going into battery charge mode so I know that it is getting a connection to the PC, but when I run LSUSB this is what I get:

landon@Core2Duo:~$ lsusb

landon@Core2Duo:~$

It does not show up in Places - Computer either, although if I plug in my old Phillips 512meg MP3 player it works just fine.

If I run GPARTED it shows both of my SATA hard drives and the SD memory card for my camera that is plugged into the 12-in-1 card reader that is listed above in the LSUSB dump.

Any suggestions on getting this to work?

I have the same issue with a Coby MP815. It charges, but will not be recognized as a hard drive. I've tried it in both USB modes.

I dual-boot to XP, and Windows sees it fine in either mode.

I've heard it has something to to with the firmware in the player, but I've not seen anything definitive on it. It would be nice to have a solution.

It works with virtualbox-nonfree, and you also have to go through some steps to make sure you can use USB devices, which are posted here: http://ubuntuforums.org/showpost.php?p=9756001&postcount=2

After you get say Windows XP installed on VirtualBox, plug it in (The mp3 player) and go to Settins > USB and add a filter for it based on device connected, so you will have a filter that says COBY. After that, unplug the mp3 player and boot windows. After Windows is booted, plug in the mp3 player and Windows should detect it and start installing it as a removable device.

I didn't much worry about this since my last car was totaled and my new car didn't have any way to plug an MP3 player into it, I have another stereo in it now that I can plug the MP3 player into and would like it get this working.

I seem to have three problems...

1 - If the MP3 player is plugged into the USB port and I boot up the PC it hangs and sometimes Ubuntu won't load, or if Ubuntu does load neither the keyboard or the mouse's lights will light up leaving me no way to do anything. If the MP3 player is not plugged into the USB port Ubuntu loads like it should.

2 - If I plug in my USB thumb drive (it is storage not the MP3 player) it detects it and lets me use it but is read only, same with my digital camera (read only), both of these devices worked fine under Ubuntu 10.10.

3 - Assuming the PC boots up and I can login normally... when I plug in the COBY MP3 player it lights up and goes into recharge mode but no icons appear on the screen like they do for the camera and thumb drive.

The MP3 player works like it is supposed to if I plug it into my other PC that runs Windows XP, any suggestions on getting it to work with Ubuntu?

Sorry to bump, but my son just got the Coby MP826 for his birthday. I've got the same problem. I don't have Windows, so Virtualbox is not an option.

Has anyone got an idea on how to get it working?

I got the same player (Coby MP826-8G), and it doesn't work in Ubuntu (11.04 nor 11.10). There is a thread for libmtp at sourceforge:
http://sourceforge.net/projects/libmtp/forums/forum/535190/topic/3931702
about this player, but it was started last year, and still no response. I guess the chances are very slim at the moment that this will work with anything but Windows...

I got it to work. Basically, it needs the "usb-storage.quirks=1e74:4631:mw" kernel parameter. A straightforward way to add that is to create a file /etc/modprobe.d/coby-option.conf with the following content:



options usb-storage quirks=1e74:4631:mw


Then, unload/reload the usb-storage module with the commands:



$ sudo modprobe -r usb-storage
$ sudo modprobe usb-storage



In the above example, 1e74:4631 is the USB ID of my Coby MP826-8G player. This may differ somewhat if you have a different model. You can find the USB ID of your player with the "lsusb" command, and adjust the line above as appropriate.

I have tested on precise and lucid. Transfer is pretty slow, but it works.

My case is a little bit worse:

I have a non-identifiable MP3 and it is not recognized in 12.04, I don't know the brand because it is one of those made in China and re-branded in the sale country (New Zealand, in my case). It is seen as standard USB disk drive by Win XP on the same machine, in Ubuntu it only charge though, cannot access the contents. Here is some output:

Solved using EtienneG's techinique. Mine was " 4641" instead of " 4631", thanks!

[SeijiSensei]

Can you post a link to setting this "quirks" parameter? I've had problems with connecting cell phones as a USB mass storage device. Though there are bug postings at Launchpad on this subject, I've never gotten a good response from the kernel developers.

Big vote of thanks from me to EtienneG.

Tweak worked for me also - across two hosts - one at 11.10 and one at 12.04.
Like Mudito - mine was a 1e74:4641
Seems to be a pretty solid tweak
