I am trying to access my new Sansa Clip+ with Amarok 2.2-GIT (built today) via MTP.
After compiling latest libmtp from CVS and mtpfs from SVN, I was able to mount it to some folder and access MTP files from the player manually.

But still, Amarok does not recognize my Clip+ as "portable media player".
After plugging the device on, I get this log output:

Code: Select all

amarok: BEGIN: void MediaDeviceCache::slotAddSolidDevice(const QString&)
amarok:   [MediaDeviceCache] Found new Solid device with udi =  "/org/freedesktop/Hal/devices/usb_device_781_74d0_7803F9027042B6A80000000000000000"

Switching the Clip+ to Mass Storage mode does work, but I'd like to try MTP, if that is possible.

Mine doesn't work either, with Amarok 2.2-Git, and LibMTP 1.0.1.

However, I'm on Kubuntu 9.10, and I have all sorts of issues with USB devices randomly not being found (HDDs, Sansa, Keyboard...), so I can't really tell what is to blame here.

Very sucky situation

My Sansa Clip+ is recognized, I can copy to but not from. Using Amarok 2.2-git, KDE SC 4.4 beta 2 on Kubuntu 9.10, libmtp 1.0.1
Also playing from the device fails: "Too many errors encountered"

I will test this now. By pure luck I got my distro to recognize the Sansa. Will post results later.


PS: You don't have a "Clip+", Mamarok. You have the "Clip", which is slightly different.

Yeah, same problem here. It is possible that my patch (using Smart Pointers) did break something. Or LibMTP is to blame, not sure yet.

Will try reverting/fixing my patch.


PS: The commit was this, you can also try to revert it locally:

Ok, reverted:

Remove smart pointer usage in MtpHandler.

Gah. Basically, all attempts of using smart pointers with this library
are doomed to fail, as the thing is written in pure C, using malloc/free.

There are many great libraries. LibMTP isn't one of them.

Last night I forgot to make install mtpfs, I just used the local executable from the compile directory.

Today I uninstalled Kubuntu's (9.10) mtpfs and installed the self compiled one (into /usr/bin/), and now Amarok recognizes my Clip+ and shows it above my Local Collection, and I can play tracks from it.

My only problem is now, how do I add Music to it in Amarok?
I can't drag&drop tracks into it.

Right click on the track you want to add and choose the Option "Copy to collection"

Thanks for the quick help!

Hello,

I am having the same issue with my Sansa Clip+, it is not recognized by the system.
Im running Kubuntu 9.10 with KDE 4.4 and Amarok 2.3.
I already installed the latest libmtp and mtp-tools(1.0.2-2). Do I need any other packages?
I tried mounting the device with mptfs without success.

What did you do fpe to get yours working?

Try to use the latest CVS version of libmtp instead of the Ubuntu packages:
http://libmtp.sourceforge.net/download.php -> "CVS Checkout".

Also you might need a newer (SVN) version of mtpfs: http://code.google.com/p/mtpfs/source/checkout
With this newer versions, it worked for me back then.

I'm not using MTP anymore, instead I use the Mass Storage Decive mode of my Sansa Clip, which is much easier to handle.

Thanks for your quick reply!
With this CVS Version mtpfs is working! Thank you very much!
Why aren't you using mtp now?

You might run Amarok from the console,

Code: Select all

amarok -d --nofork

and watch there what happens when you plug in your device. USB can be mighty touchy when it interacts with KDE. My own device only shows up about half the time, and sometimes I have to plug it in THREE times before it's detected.
