+<p>Early this month I set out to try to
+<a href="http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">improve
+the Debian support for pluggable hardware devices</a>. Now my
+prototype is working, and it is ready for a larger audience. To test
+it, fetch the
+<a href="http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">source
+from the Debian Edu subversion repository</a>, build and install the
+package. You might have to log out and in again activate the
+autostart script.</p>
+
+<p>The design is simple:</p>
+
+<ul>
+
+<li>Add desktop entry in /usr/share/autostart/ causing a program
+hw-support-handlerd to start when the user log in.</li>
+
+<li>This program listen for kernel events about new hardware (directly
+from the kernel like udev does).</li>
+
+<li>When new hardware is inserted, look up the hardware modalias in
+the APT database, a database available via HTTP and a database
+available as part of the package.</li>
+
+<li>If a package is mapped to the hardware in question, the package
+isn't installed yet and this is the first time the hardware was
+plugged in, show a desktop notification suggesting to install the
+package or packages.</li>
+
+<li>If the user click on the 'install package now' button, ask
+aptdaemon via the PackageKit API to install the requrired package.</li>
+
+<li>aptdaemon ask for root password or sudo password, and install the
+package while showing progress information in a window.</li>
+
+</ul>
+
+<p>I still need to come up with a better name for the system. Here
+are some screen shots showing the prototype in action. First the
+notification, then the password request, and finally the request to
+approve all the dependencies. Sorry for the Norwegian Bokmål GUI.</p>

+
+<p>The prototype still need to be improved with longer timeouts, but
+is already useful. The database of hardware to package mappings also
+need more work. It is currently compatible with the Ubuntu way of
+storing such information in the package control file, but could be
+changed to use other formats instead or in addition to the current
+method. I've dropped the use of discover for this mapping, as the
+modalias approach is more flexible and easier to use on Linux as long
+as the Kernel expose its modalias strings directly.</p>
