Subject: [PATCH] HID: roccat: add driver for Roccat Pyra mouse
This patch add support for Pyra mobile gaming mouse from Roccat.
It provides access to profiles, settings, actual settings etc.
through sysfs attributes.
This driver is conceptual similar to the existing Kone driver.
Userland tools can soon be found at http://sourceforge.net/projects/roccat

+Description: It is possible to switch the cpi setting of the mouse with the
+ press of a button.
+ When read, this file returns the raw number of the actual cpi
+ setting reported by the mouse. This number has to be further
+ processed to receive the real dpi value.

+Description: When read, this file returns the raw integer version number of the

+ number the decimal point has to be shifted 2 positions to the
