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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

+Description:	When read, this file returns the raw integer version number of the
+		firmware reported by the mouse. Using the integer value eases
+		further usage in other programs. To receive the real version
+		number the decimal point has to be shifted 2 positions to the
+		left. E.g. a returned value of 121 means 1.21

+		When written, this file lets one write the respective profile
+		buttons back to the mouse. The data has to be 77 bytes long.
+		The mouse will reject invalid data.
+		Which profile to write is determined by the profile number
+		contained in the data.
