HID: roccat: Add support for Roccat Kone[+] v2
Stefan Achatz [Fri, 26 Nov 2010 19:57:42 +0000 (19:57 +0000)]
This patch adds support for Roccat Kone[+] gaming mouse. Kone[+] is an enhanced version
of the old Kone with more memory for macros, a better sensor and more functionality.
This driver is conceptual similar to the existing Kone and Pyra drivers.
Userland tools can soon be found at http://sourceforge.net/projects/roccat
