I'd appreciate some help with running a Griffin PowerMate USB volume controller on my new 64 bit 12.04 desktop - to control / mute the machine's master volume, & scroll through cbr files.

According to Google & SourceForge, something called Gizmo Daemon / Gizmod was the way to go until a while ago, but I've only found one site on it that's recent - and the method proposed is a bit too much of a leap for me at this point....

I am very new to Ubuntu so ideally I'd really appreciate some clear instructions - and a ready-to-rock package if there's one out there.

Cheers, Dave - an Aussie in Glasgow, Scotland.

Thanks for that @mateo_salta - I did as suggested, though installation of the deb.zip failed :( Here's what the end of the text in the installation window came out with : Setting up moc (1:2.5.0~alpha4+svn20120224-1ubuntu1) ... Processing triggers for libc-bin ... ldconfig deferred processing now taking place dpkg: error processing /home/david/hesus-powermate_1.2-0_all.deb (--install): parsing file '/var/lib/dpkg/tmp.ci/control' near line 11 package 'hesus-powermate': blank line in value of field 'Description' –  David May 17 '12 at 22:34

For a very long time I had been struggling to get powermate working in Ubuntu, my favourite OS. It was frustrating and finally I got it going and I do want to share with you all how I did. My sincere thanks to all the people from the references. I needed something more definitive, there is none available. Therefore this endeavour.

This is how I got my volume control with Griffin Powermate USB device working in Ubuntu Saucy Salamander 13.10 amd64. Please bear with me and do the following.

A. Make a file "/etc/udev/rules.d/10-local.rules" and put the following in the file

# sudo gedit /etc/udev/rules.d/10-local.rules

code line:

SUBSYSTEMS=="usb", ATTRS{product}=="Griffin PowerMate", KERNEL=="event?", NAME="input/powermate"

Save and close

B. Create group called "powermate" add yourself and other users to that group, you can give it a GID of 1001 or some like that. You can do so by editing the file /etc/group

# sudo gedit /etc/group

code line: powermate:x:1001:your-user-name

C. Now edit / make file "/etc/udev/rules.d/40-permissions.rules" and add the following

# sudo gedit /etc/udev/rules.d/40-permissions.rules

code lines:

ATTRS{product}=="Griffin PowerMate" GROUP="powermate", MODE="0666"

Save and close.

D. Download and install evrouter from: http://www.bedroomlan.org/projects/evrouter or use the repository at http://www.bedroomlan.org/bedroomlan-debian-repository

E. Create /etc/evrouterrc (or $HOME/.evrouterrc, I prefer /etc/evrouterrc) with the following:

# sudo gedit /etc/evrouterrc

code lines:

Window ""
"Griffin PowerMate" "" any key/256 "XKey/XF86AudioMute"
"Griffin PowerMate" "" any rel/7/1 "XKey/XF86AudioRaiseVolume"
"Griffin PowerMate" "" any rel/7/-1 "XKey/XF86AudioLowerVolume"

F. Find out the powermate input event number (in mine it is event7), by running the following command.

# evrouter /dev/input/*

In the long output, you should see a line like the following

device  0: /dev/input/event7: Griffin PowerMate

G. Create /usr/local/bin/powermate with:

# sudo gedit /usr/local/bin/powermate

code lines:

evrouter -c /etc/evrouterrc /dev/input/event7

H. If you are a lazy guy like me and would like it to autorun at start up, you can do so by adding the script file to, /etc/rc.local or any such other.

# sudo gedit /etc/rc.local

code line (add before exit 0 line):


Save and close.

Try it and see. Best of luck. I love it now. Hopefully you folks can get it working it too.

Worked for me! The only missing command is sudo chmod +x /usr/local/bin/powermate –  defrex Dec 13 '13 at 23:08

You can find an DEB-File on this forum:


It is currently only for older Ubuntu Version but there will be a new version.

Will the new version be on the forum, or a different location? –  hexafraction Oct 3 '12 at 11:25

On my system, running Kubuntu 12.10, there is a device /dev/input/powermate that I can call up in the same /usr/local/bin/powermate that works correctly; I don't need to worry about the input number. This can be useful for when the input number changes.
