HID: roccat: add support for Roccat Savu
This patch adds rupport for Roccat Savu gaming mouse. In comparison to the other Roccat modules I tried to move even more functionality to userland. Userland tools can soon be found at http://sourceforge.net/projects/roccat Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Description: The mouse can store 5 profiles which can be switched by the
|
||||
press of a button. A profile is split into general settings and
|
||||
button settings. buttons holds informations about button layout.
|
||||
When written, this file lets one write the respective profile
|
||||
buttons to the mouse. The data has to be 47 bytes long.
|
||||
The mouse will reject invalid data.
|
||||
Which profile to write is determined by the profile number
|
||||
contained in the data.
|
||||
Before reading this file, control has to be written to select
|
||||
which profile to read.

Description: The mouse can store 5 profiles which can be switched by the
|
||||
press of a button. profile holds number of actual profile.
|
||||
This value is persistent, so its value determines the profile
|
||||
that's active when the mouse is powered on next time.
|
||||
When written, the mouse activates the set profile immediately.
|
||||
The data has to be 3 bytes long.
|
||||
The mouse will reject invalid data.
