How to make the Griffin Powermate (USB) version control audio volume in Ubuntu 14.04 LTS

Create an admin group called “powermate” and add yourself to it:

sudo addgroup --system powermate
sudo usermod -a -G powermate user


Log out and back in.


Create the udev entry that will notice the powermate when you plug it in. Create /etc/udev/rules.d/powermate.rules with the following content:


SUBSYSTEM=="input", ATTRS{idVendor}=="077d", ATTRS{idProduct}=="0410", SYMLINK+="powermate", MODE="660", GROUP="powermate"

sudo restart udev


Install evrouter from http://www.bedroomlan.org/projects/evrouter


Create $HOME/.evrouterrc with the following content:


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


Start it with:


evrouter -c $HOME/.evrouterrc /dev/powermate


Set it to start automatically by adding it to startup programs ({superkey}+”startup”).



Smile every time you change the volume!  And yes I know it's been a year since I've posted. Just had to get this out while it's fresh in my mind.  Deal with it.  The writing itch is coming back...
