Many COWON audio players are Linux-friendly portable media devices. Most (modern) devices support the following:

  • OGG/FLAC support (as well as MP3/WMA/APE/WAV)
  • ID3 tag support
  • M3U playlist support
  • AVI/WMV/ASF video support with DivX 3/4/5 and Xvid SP/ASP codec support
  • Gapless playback and Semi-parametric equalizer (for audiophiles)

This page will help you connect your COWON media player with the Banshee Media Player (version 1.8.1 +) on Ubuntu 10.04 and higher.

This method is known to work for a number of COWON audio devices, although there's no guarantee that it'll work for all. Among those that it should work for are:

  • D2/D2+
  • J3
  • S9
  • iAUDIO 9

Preparing Banshee

In order for Banshee to recognize your COWON as a media device, it requires Mass Storage Media Player Support:

  • Open Banshee.
  • On the menu bar, select Edit > Preferences.

  • Navigate to the Extensions tab, and scroll down to Device Support.
  • Ensure that the "Mass Storage Media Player Support" extension is enabled.

This should be a core extension and shipped with Banshee by default.

When this is completed, quit Banshee for now and proceed with preparing your COWON.

Preparing Your COWON

Enabling Mass Storage Class Mode

In order for your Cowon to mount as a regular USB hard drive, it should be in Mass Storage Class (MSC) mode and not in Media Transfer Protocol (MTP) mode. To make or confirm this change:

  • Navigate to the device's Settings screen.
  • Select System.
  • Scroll down to USB Mode and choose "MSC".

Creating the .is_audio_player File

Connect your COWON via USB and wait for it to appear as a USB Mass Storage device on your desktop. Ignore Ubuntu's prompts to open Rhythmbox/Banshee and simply double click the desktop icon for your device to browse its root directory. You should see folders entitled Music, Pictures, System, Flash, etc.

If you plan to use an external memory card within the device, navigate to the root of this, and not the root of the device's memory. For example, some devices will have two locations mounted, internet and external memory.

Banshee expects unknown Mass Storage media players to contain a file called .is_audio_player (note the dot preceding the name - this is a hidden file) in the root directory of the device. Create this file using your favourite text editor and paste the following text into it verbatim:

cover_art_size = 272

Insert the device name (i.e., J3) for DEVICE_NAME. Change the cover art size as required on the device. J3 and S9 are presumed to used 272 pixels.

Save the file and quit your text editor.

Enabling Playlist Support (mostly)

At this point, Banshee will be able to recognize your COWON and sync music with it. M3U Playlists will also synchronize but will not actually play on the device. This is because the COWON expects DOS-style paths (\ instead of /) and absolute paths (which are relative to the root of the device). Banshee's M3U playlists use UNIX-style paths which are relative to the Music directory.

As a temporary fix for this issue, create a script called in your home folder using your favourite text editor and paste the following text into it verbatim:

# Convert Unix m3u files created by banshee, mpd, and other music managers
#   into a format that the Cowon S9/J3 can understand.
# Original Script by (c) 2009 James Ogley
# This version uses tofrodos.

#change directory to Cowon Device
cd '/media/COWON DEVICE_NAME/Music'
# Change paths to absolute paths
sed -i '/^[^#]/ s?^?/Music/?' *.m3u
# Convert all UNIX slashes to DOS backslashes
sed -i '/^\// s/\//\\/g' *.m3u
# Convert Unix line endings to DOS line endings
todos -uo *.m3u

Again, change DEVICE_NAME with the device model.

Do not forget to make this script executable by right-clicking on it, choosing Properties, navigating to the Permissions tab and selecting Allow executing file as program -- or, if you prefer, make the change via the command line:

$ chmod a+x

You can now place the script in /home/USER_NAME_HERE/.gnome2/nautilus-scripts and will be able to run it from Nautilus by a simple right click. The following command will make the move for you automatically.

$ mv /$HOME/ /$HOME/.gnome2/nautilus-scripts

Also, if you are missing dependencies for the script, please install them using apt-get or aptitude:

$ sudo apt-get install sed tofrodos

Please note that this script was originally designed by James Ogley (see below) and has been modified for compatibility with Ubuntu 10.04+.

Discussion of the usage of this script follows.

Syncing your Music Library

Now that you have prepared Banshee and your COWON, you may synchronize your music library and playlists by following these steps:

  1. Open Banshee Media Player
  2. Connect your COWON to your computer via USB
  3. Wait for your COWON to appear on the far left of the Banshee interface (likely at the bottom of the list below Music,Videos,etc.)

  4. Select your COWON from the list on the far left of the Banshee interface
  5. Allow Banshee to scan the device for existing media files (this may take some time)
  6. Under Sync Preferences in the middle of the interface, choose the Sync entire library option in the drop-down list for Music and select the Sync when first plugged in and when libraries change checkbox

  7. Banshee should now synchronize your music library and playlists automatically. If it does not begin synchronizing, try clicking the Sync in the upper right-hand corner of the Banshee interface.

  8. When Banshee is finished synchronizing your music and playlists, exit the program completely.

  9. Right click anywhere in Nautilus and find the sub-menu called Scripts. From there, you can select the script to run it and convert Banshee's synchronized playlists into the format your COWON will understand.

  10. Safely eject/disconnect your COWON from your computer
  11. Enjoy your tunes!
