119 <a href=
"http://people.skolelinux.org/pere/blog/First_prototype_ready_making_hardware_easier_to_use_in_Debian.html">asked
120 for testers
</a> for my prototype for making Debian better at handling
121 pluggable hardware devices, which I
122 <a href=
"http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">set
123 out to create
</a> earlier this month. Several valuable testers showed
124 up, and caused me to really want to to open up the development to more
125 people. But before I did this, I want to come up with a sensible name
126 for this project. Today I finally decided on a new name, and I have
127 renamed the project from hw-support-handler to this new name. In the
128 process, I moved the source to git and made it available as a
129 <a href=
"http://anonscm.debian.org/gitweb/?p=collab-maint/isenkram.git">collab-maint
</a>
130 repository in Debian. The new name? It is
<strong>Isenkram
</strong>.
131 To fetch and build the latest version of the source, use
</p>
134 git clone http://anonscm.debian.org/git/collab-maint/isenkram.git
135 cd isenkram && git-buildpackage -us -uc
138 <p>I have not yet adjusted all files to use the new name yet. If you
139 want to hack on the source or improve the package, please go ahead.
140 But please talk to me first on IRC or via email before you do major
141 changes, to make sure we do not step on each others toes. :)
</p>
143 <p>If you wonder what 'isenkram' is, it is a Norwegian word for iron
144 stuff, typically meaning tools, nails, screws, etc. Typical hardware
145 stuff, in other words. I've been told it is the Norwegian variant of
146 the German word eisenkram, for those that are familiar with that

170 <a href=
"http://people.skolelinux.org/pere/blog/Lets_make_hardware_dongles_easier_to_use_in_Debian.html">improve
171 the Debian support for pluggable hardware devices
</a>. Now my

174 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/">source
175 from the Debian Edu subversion repository
</a>, build and install the
176 package. You might have to log out and in again activate the
177 autostart script.
</p>
179 <p>The design is simple:
</p>
183 <li>Add desktop entry in /usr/share/autostart/ causing a program
184 hw-support-handlerd to start when the user log in.
</li>
186 <li>This program listen for kernel events about new hardware (directly
187 from the kernel like udev does), not using HAL dbus events as I
190 <li>When new hardware is inserted, look up the hardware modalias in
191 the APT database, a database
192 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=markup">available
193 via HTTP
</a> and a database available as part of the package.
</li>
195 <li>If a package is mapped to the hardware in question, the package
196 isn't installed yet and this is the first time the hardware was
197 plugged in, show a desktop notification suggesting to install the
198 package or packages.
</li>
200 <li>If the user click on the 'install package now' button, ask
201 aptdaemon via the PackageKit API to install the requrired package.
</li>
203 <li>aptdaemon ask for root password or sudo password, and install the
204 package while showing progress information in a window.
</li>
208 <p>I still need to come up with a better name for the system. Here
209 are some screen shots showing the prototype in action. First the
210 notification, then the password request, and finally the request to
211 approve all the dependencies. Sorry for the Norwegian Bokmål GUI.

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

228 <p><strong>Update
2013-
01-
21 16:
50</strong>: Due to popular demand,
229 here is the command required to check out and build the source: Use

232 hw-support-handler; debuild

233 devscripts package.

235 <p><strong>Update
2013-

255 suddenly in bed. With a quiet whimper, it went completely quiet and
256 black. The power button was no longer able to turn it on. It was a
257 IBM Thinkpad X41, and the best laptop I ever had. Better than both
258 Thinkpads X30, X31, X40, X60, X61 and X61S. Far better than the
259 Compaq I had before that. Now I need to find a replacement. To keep
260 going during Christmas, I moved the one year old SSD disk to my old
261 X40 where it fitted (only one I had left that could use it), but it is
262 not a durable solution.

290 at other features to choose my laptop. But are there still made as
291 robust laptops as my X41? The Thinkpad X60/X61 proved to be less
292 robust, and Thinkpads seem to be heading in the wrong direction since
293 Lenovo took over. But I've been told that X220 and X1 Carbon might

297 external keyboard? I'll have to check the

317 install to get support for a given MIME type. Thanks to
318 <a href=
"https://wiki.ubuntu.com/MozillaTeam/Plugins">specifications
319 done by Ubuntu
</a> and Mozilla, it is possible to do this in Debian.
320 Unfortunately, not very many packages provide the needed meta
321 information, Anyway, here is a small script to look up all browser
322 plugin packages announcing ther MIME support using this specification:
</p>
328 def pkgs_handling_mimetype(mimetype):
333 version = pkg.candidate
335 version = pkg.installed
338 record = version.record
339 if not record.has_key('Npp-MimeType'):
341 mime_types = record['Npp-MimeType'].split(',')
343 t = t.rstrip().strip()
345 thepkgs.append(pkg.name)
347 mimetype = "audio/ogg"
348 if
1 < len(sys.argv):
349 mimetype = sys.argv[
1]
350 print "Browser plugin packages supporting %s:" % mimetype
351 for pkg in pkgs_handling_mimetype(mimetype):
355 <p>It can be used like this to look up a given MIME type:
</p>
358 % ./apt-find-browserplug-for-mimetype
359 Browser plugin packages supporting audio/ogg:
361 % ./apt-find-browserplug-for-mimetype application/x-shockwave-flash
362 Browser plugin packages supporting application/x-shockwave-flash:
367 <p>In Ubuntu this mechanism is combined with support in the browser
368 itself to query for plugins and propose to install the needed
369 packages. It would be great if Debian supported such feature too. Is
370 anyone working on adding it?
</p>
372 <p><strong>Update
2013-

373 request for icweasel support for this feature is

484010</a> from
2008 (and
375 <a href=

698426</a> from today). Lack
376 of manpower and wish for a different design is the reason thus feature
377 is not yet in iceweasel from Debian.

0E01):
</p>
542 <br>Modaliases: cheese(usb:v*p*d*dc*dsc*dp*ic0Eisc01ip*)
</p>
545 <p>An entry like this would suggest the pcmciautils package when a
546 CardBus bridge (bus class
0607) PCI device is present:
</p>
550 <br>Modaliases: pcmciautils(pci:v*d*sv*sd*bc06sc07i*)
553 <p>An entry like this would suggest the package colorhug-client when
554 plugging in a ColorHug with USB IDs
04D8:F8DA:
</p>
557 Package: colorhug-client
558 <br>Modaliases: colorhug-client(usb:v04D8pF8DAd*)
</p>
561 <p>I believe the format is compatible with the format of the Packages
562 file in the Debian archive. Ubuntu already uses their Packages file
563 to store their mappings from packages to hardware.
</p>
565 <p>By adding a XB-Modaliases: header in debian/control, any .deb can
566 announce the hardware it support in a way my prototype understand.
567 This allow those publishing packages in an APT source outside the
568 Debian archive as well as those backporting packages to make sure the
569 hardware mapping are included in the package meta information. I've
570 tested such header in the pymissile package, and its modalias mapping
571 is working as it should with my prototype. It even made it to Ubuntu
574 <p>To test if it was possible to look up supported hardware using only
575 the shell tools available in the Debian installer, I wrote a shell
576 implementation of the lookup code. The idea is to create files for
577 each modalias and let the shell do the matching. Please check out and
579 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/hw-support-lookup?view=co">hw-support-lookup
</a>
580 shell script. It run without any extra dependencies and fetch the
581 hardware mappings from the Debian archive and the subversion
582 repository where I currently work on my prototype.
</p>
584 <p>When I use it on a machine with a yubikey inserted, it suggest to
585 install yubikey-personalization:
</p>
588 % ./hw-support-lookup
589 <br>yubikey-personalization
593 <p>When I run it on my Thinkpad X40 with a PCMCIA/CardBus slot, it
594 propose to install the pcmciautils package:
</p>
597 % ./hw-support-lookup
602 <p>If you know of any hardware-package mapping that should be added to
603 <a href=
"http://anonscm.debian.org/viewvc/debian-edu/trunk/src/hw-support-handler/modaliases?view=co">my
604 database
</a>, please tell me about it.
</p>
606 <p>It could be possible to generate several of the mappings between
607 packages and hardware. One source would be to look at packages with
608 kernel modules, ie packages with *.ko files in /lib/modules/, and
609 extract their modalias information. Another would be to look at
610 packages with udev rules, ie packages with files in
611 /lib/udev/rules.d/, and extract their vendor/model information to
612 generate a modalias matching rule. I have not tested any of these to
615 <p>If you want to help implementing a system to let us propose what
616 packages to install when new hardware is plugged into a Debian
617 machine, please send me an email or talk to me on

634 information, to find the packages that support a given piece of
635 hardware, I refreshed my memory regarding modalias values, and decided
636 to document the details. Here are my findings so far, also available

651 this shell script:
</p>
654 find /sys -name modalias -print0 | xargs -

662 alias: serio:ty05pr*id*ex*
663 alias: serio:ty01pr*id*ex*
667 <p><strong>PCI subtype
</strong></p>
669 <p>A typical PCI entry can look like this. This is an Intel Host
670 Bridge memory controller:
</p>
673 pci:v00008086d00002770sv00001028sd000001ADbc06sc00i00
676 <p>This represent these values:
</p>
681 sv
00001028 (subvendor)
682 sd
000001AD (subdevice)
688 <p>The vendor/device values are the same values outputted from 'lspci
689 -n' as
8086:
2770. The bus class/subclass is also shown by lspci as
690 0600. The
0600 class is a host bridge. Other useful bus values are
691 0300 (VGA compatible card) and
0200 (Ethernet controller).
</p>
693 <p>Not sure how to figure out the interface value, nor what it
696 <p><strong>USB subtype
</strong></p>
698 <p>Some typical USB entries can look like this. This is an internal
699 USB hub in a laptop:
</p>
702 usb:v1D6Bp0001d0206dc09dsc00dp00ic09isc00ip00
705 <p>Here is the values included in this alias:
</p>
708 v
1D6B (device vendor)
709 p
0001 (device product)
712 dsc
00 (device subclass)
713 dp
00 (device protocol)
714 ic
09 (interface class)
715 isc
00 (interface subclass)
716 ip
00 (interface protocol)
719 <p>The
0900 device class/subclass means hub. Some times the relevant
720 class is in the interface class section. For a simple USB web camera,
721 these alias entries show up:
</p>
724 usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc01ip00
725 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic01isc02ip00
726 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc01ip00
727 <br>usb:v0AC8p3420d5000dcEFdsc02dp01ic0Eisc02ip00
730 <p>Interface class
0E01 is video control,
0E02 is video streaming (aka
731 camera),
0101 is audio control device and
0102 is audio streaming (aka
732 microphone). Thus this is a camera with microphone included.
</p>
734 <p><strong>ACPI subtype
</strong></p>
736 <p>The ACPI type is used for several non-PCI/USB stuff. This is an IR
737 receiver in a Thinkpad X40:
</p>
740 acpi:IBM0071:PNP0511:
743 <p>The values between the colons are IDs.
</p>
745 <p><strong>DMI subtype
</strong></p>
747 <p>The DMI table contain lots of information about the computer case
748 and model. This is an entry for a IBM Thinkpad X40, fetched from
749 /sys/devices/virtual/dmi/id/modalias:

766 rvr NotAvailable (board version)
767 cvn IBM (chassis vendor)
769 cvr NotAvailable (chassis version)
772 <p>The chassis type
10 is Notebook. Other interesting values can be
773 found in the dmidecode source:
</p>
777 4 Low Profile Desktop
790 17 Main Server Chassis
793 20 Bus Expansion Chassis
794 21 Peripheral Chassis
796 23 Rack Mount Chassis
805 <p>The chassis type values are not always accurately set in the DMI
806 table. For example my home server is a tower, but the DMI modalias
807 claim it is a desktop.
</p>
809 <p><strong>SerIO subtype
</strong></p>
811 <p>This type is used for PS/
2 mouse plugs. One example is from my
815 serio:ty01pr00id00ex00
818 <p>The values present are
</p>
827 <p>This type is supported by the psmouse driver. I am not sure what
828 the valid values are.
</p>
830 <p><strong>Other subtypes
</strong></p>
832 <p>There are heaps of other modalias subtypes according to
833 file2alias.c. There is the rest of the list from that source: amba,
834 ap, bcma, ccw, css, eisa, hid, i2c, ieee1394, input, ipack, isapnp,
835 mdio, of, parisc, pcmcia, platform, scsi, sdio, spi, ssb, vio, virtio,
836 vmbus, x86cpu and zorro. I did not spend time documenting all of
837 these, as they do not seem relevant for my intended use with mapping
838 hardware to packages when new stuff is inserted during run time.
</p>
840 <p><strong>Looking up kernel modules using modalias values
</strong></p>
842 <p>To check which kernel modules provide support for a given modalias,
843 one can use the following shell script:
</p>
846 for id in $(find /sys -name modalias -print0 | xargs -
0 cat | sort -u); do \
848 /sbin/modprobe --show-depends "$id"|sed 's/^/ /' ; \
852 <p>The output can look like this (only the first few entries as the
853 list is very long on my test machine):

894 <div class=
"body"><p>As part of my investigation on how to improve the support in Debian
895 for hardware dongles, I dug up my old Mark and Spencer USB Rocket
896 Launcher and updated the Debian package
897 <a href=
"http://packages.qa.debian.org/pymissile">pymissile
</a> to make
898 sure udev will fix the device permissions when it is plugged in. I
899 also added a "Modaliases" header to test it in the Debian archive and
900 hopefully make the package be proposed by jockey in Ubuntu when a user
901 plug in his rocket launcher. In the process I moved the source to a
902 git repository under collab-maint, to make it easier for any DD to
903 contribute.

904 is not very active, but the software still work for me even after five
905 years of relative silence. The new git repository is not listed in
906 the uploaded package yet, because I want to test the other changes a
907 bit more before I upload the new version. If you want to check out
908 the new version with a .desktop file included, visit the
