    Subject[PATCH] HID: roccat: Add support for Roccat Kone[+]
    From
    Date
    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
