Linux driver for the Griffin Powermate
Downloads:
Information:
The driver exports a simple event interface; the tarball above contains a
pair of demo apps, one for reading movement from the powermate, and one for
configuring the LED in the base. Any software which understands the Linux
event interface should be interoperable with the PowerMate -- unfortunately
this interface is relatively new, but I'm sure apps will follow.
Dale Martin has written up some
advice on making this all work which may be helpful to you.

You should be able to get up and running by applying the kernel patch above
to a 2.4.21 kernel and recompiling. You'll need to configure your
kernel with CONFIG_INPUT, CONFIG_INPUT_EVDEV, CONFIG_USB, CONFIG_USB_HID
and CONFIG_USB_POWERMATE set. The patch adds support for Griffin's latest
revision of the PowerMate hardware. The 2.4.21 kernel driver supports the older
hardware revision without modification.
