If you want to use just the file browsing or program installation stuff, you only need to install synce-hal and librapi2-tools. If you want to sync, see below.
Syncing with OpenSync
In order to sync your device you need to use OpenSync. We'll install multisync-tools to control sync, the WM2003 support plugin and the evolution plugin. KDE users can use opensync-plugin-kdepim instead of the evolution2 plugin. There is no Thunderbird support in any stable opensync release.
sudo apt-get install multisync-tools opensync-plugin-evolution opensync-plugin-synce-legacy
You need to create a partnership with your device.
synce-matchmaker create
There is some one time setup for opensync.
msynctool --addgroup synce-sync msynctool --addmember synce-sync synce-plugin msynctool --addmember synce-sync evo2-sync msynctool --configure synce-sync 1
The last command opens up a text editor. Make yours something like this and save and exit.
<config>
<contact></contact>
<todos></todos>
<calendar></calendar>
<file></file>
</config>Then sync is:
msynctool --sync synce-sync
