Making It Work
On July 4, 2010, KernelLabs released a beta driver for this device. It is intended to be merged upstream once it has been cleaned up to meet the Linux kernel coding standards. More Information can be found in this blog post: KernelLabs blog
Note: The patches do not work with current kernels like 2.6-35 due to changes in the surrounding mainline kernel (API breakage).
In October 2011, Patrick Dickey created a project on Github to clean up the code an apply it to the latest base code at the time. It can be found at: [4] The readme has very good information on how to get it to work.
