Griffin PowerMate

Postby shdawson » Sat Jun 23, 2012 2:50 pm


Writing for help to get my Griffin PowerMate running in Linux Mint, please. This is the device:

Pretty nice device, I used it a lot in my Windows life. Now, in Linux Mint...trying to get some degree of functionality working. Being able to just vertically scroll in a browser or Libre Office would do for now, although configuring it to perform different functions in the future would be great.

Working with a good friend to get things going. So far, the following has been tried.

1) A udev rule was created in /etc/udev/rules.d/99-input.rules:

Code: Select all

BUS=="usb", KERNEL=="event*", SYSFS{product}=="PowerMate", NAME="input/%k", SYMLINK+="powermate", MODE="0660", GROUP="input"

2) An evdev config file /usr/share/X11/xorg.conf.d/12-evdev-powermate.conf was added:

Code: Select all

Section "InputClass"
        Identifier      "evdev Griffin PowerMate catchall"
        MatchVendor     "077d"
        MatchDevicePath "/dev/input/event*"
        Option  "EmulateWheel"  "true"
        Option  "Emulate3Buttons"       "false"
        Option  "YAxisMapping"  "4 5"

lsusb shows:

Code: Select all

        bInterval              10

However, the xserver complains that it does not find a driver, which means that evdev does not pick it up:

Code: Select all

[   272.416] (II) config/udev: Adding input device Griffin PowerMate (/dev/input/event11)
[   272.417] (II) No input driver specified, ignoring this device.
[   272.417] (II) This device may have been added with another device file.

I have emailed Griffin Technologies, in hope that they may provide advice suitable for Linux. They kindly shared their SDK for Windows and Mac with me, but I am not a developer to be able to use it. :(

Google tells me that the gizmod application was been taken off the tree a few years ago because its not being developed anymore. This was able to map the PowerMate actions to functions of individual applications. I can't find anything in Synaptic for this purpose, but I may not be looking for the right thing.

What can be done to get this working, please? What further information do I need to provide to the forum?

Has anyone configured this to work with Mint?

Thank you very much.
