+		<description>&lt;p&gt;I received a very nice Christmas present today.  As my regular
+readers probably know, I have been working on the
+&lt;a href=&quot;http://packages.qa.debian.org/isenkram&quot;&gt;the Isenkram
+system&lt;/a&gt; for many years.  The goal of the Isenkram system is to make
+it easier for users to figure out what to install to get a given piece
+of hardware to work in Debian, and a key part of this system is a way
+to map hardware to packages.  Isenkram have its own mapping database,
+and also uses data provided by each package using the AppStream
+metadata format.  And today,
+&lt;a href=&quot;https://tracker.debian.org/pkg/appstream&quot;&gt;AppStream&lt;/a&gt; in
+Debian learned to look up hardware the same way Isenkram is doing it,
+ie using fnmatch():&lt;/p&gt;
+
+&lt;p&gt;&lt;pre&gt;
+% appstreamcli what-provides modalias \
+  usb:v1130p0202d0100dc00dsc00dp00ic03isc00ip00in00
+Identifier: pymissile [generic]
+Name: pymissile
+Summary: Control original Striker USB Missile Launcher
+Package: pymissile
+% appstreamcli what-provides modalias usb:v0694p0002d0000
+Identifier: libnxt [generic]
+Name: libnxt
+Summary: utility library for talking to the LEGO Mindstorms NXT brick
+Package: libnxt
+---
+Identifier: t2n [generic]
+Name: t2n
+Summary: Simple command-line tool for Lego NXT
+Package: t2n
+---
+Identifier: python-nxt [generic]
+Name: python-nxt
+Summary: Python driver/interface/wrapper for the Lego Mindstorms NXT robot
+Package: python-nxt
+---
+Identifier: nbc [generic]
+Name: nbc
+Summary: C compiler for LEGO Mindstorms NXT bricks
+Package: nbc
+%
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;A similar query can be done using the combined AppStream and
+Isenkram databases using the isenkram-lookup tool:&lt;/p&gt;
+
+&lt;p&gt;&lt;pre&gt;
+% isenkram-lookup usb:v1130p0202d0100dc00dsc00dp00ic03isc00ip00in00
+pymissile
+% isenkram-lookup usb:v0694p0002d0000
+libnxt
+nbc
+python-nxt
+t2n
+%
+&lt;/pre&gt;&lt;/p&gt;
+
+&lt;p&gt;You can find modalias values relevant for your machine using
+&lt;tt&gt;cat $(find /sys/devices/ -name modalias)&lt;/tt&gt;.
+
+&lt;p&gt;If you want to make this system a success and help Debian users
+make the most of the hardware they have, please
+help&lt;a href=&quot;https://wiki.debian.org/AppStream/Guidelines&quot;&gt;add
+AppStream metadata for your package following the guidelines&lt;/a&gt;
+documented in the wiki.  So far only 11 packages provide such
+information, among the several hundred hardware specific packages in
+Debian. The Isenkram database on the other hand contain 101 packages,
+mostly related to USB dongles.  Most of the packages with hardware
+mapping in AppStream are LEGO Mindstorms related, because I have, as
+part of my involvement in
+&lt;a href=&quot;https://wiki.debian.org/LegoDesigners&quot;&gt;the Debian LEGO
+team&lt;/a&gt; given priority to making sure LEGO users get proposed the
+complete set of packages in Debian for that particular hardware.  The
+team also got a nice Christmas present today.  The
+&lt;a href=&quot;https://tracker.debian.org/pkg/nxt-firmware&quot;&gt;nxt-firmware
+package&lt;/a&gt; made it into Debian.  With this package in place, it is
+now possible to use the LEGO Mindstorms NXT unit with only free
+software, as the nxt-firmware package contain the source and firmware
+binaries for the NXT brick.&lt;/p&gt;
+
+&lt;p&gt;As usual, if you use Bitcoin and want to show your support of my
+activities, please send Bitcoin donations to my address
+&lt;b&gt;&lt;a href=&quot;bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&amp;label=PetterReinholdtsenBlog&quot;&gt;15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b&lt;/a&gt;&lt;/b&gt;.&lt;/p&gt;
