Girder plug-in for PowerMate
Version 3.1. MMcM 09/05
This plug-in interfaces to the Griffin PowerMate USB control knob.
Events are generated when the knob turns or is pressed. The event
payload is the increment as a decimal number. Almost always, this is
1, since the program keeps up with the device. To handle
this properly as a count, such as when simulating keyboard input, an
action is provided that calls a command
Additional actions are provided to adjust the LED on the knob: its
brightness and whether it pulses.

here; source is also available
These are the files contained in this archive and what purpose they serve.
The PowrMate.sys device driver must be installed, but the
PowerMate.exe program must not be running. Normally it
starts with Windows. You may need to remove it from
using regedit or msconfig.
The PowerMate device driver must be version 1.5 or newer. Non-blocking I/O does not
work properly in earlier releases and the plug-in depends upon it.
