-This module works with the Griffin Powermate and allows some basic transport control.
-
-It autodetects the Powermate on any input device of the form "/dev/input/event*".  This means you must have the powermate module in your kernel.  It works out-of-the-box with 64Studio and presumably lots of other modern distributions.
-
-Turning the wheel left and right will act as a "Shuttle" wheel, adjusting playback speed up and down
-Pushing the knob will switch between play and stop
-Pushing the knob while turning will jump to the next or previous markers
-
-
-In order for the powermate to work, you have to have permission to open the input device for reading.
-In debian, I changed /etc/udev/rules.d/0_permissions.rules to have the line:
-KERNEL=="event[0-9]*", 		MODE="0666"
-but there are other ways to achieve this
-
-
-Feedback, tweaks, bug fixes and feature ideas are encouraged
