Description Blaž Tomažič 2015-03-24 09:33:38 UTC 
Product specs, windows and linux tools (http://roccat.sourceforge.net/) show next values:
  * DPI: 250 500 1000 1250 1500 1750 2000
  * Hz: 125 250 500 1000
  * default: 1000DPI 1000Hz

Using this info and match string from mouse-dpi-tool, 70-mouse.hwdb should contain:

mouse:usb:v1e7dp2c2e:name:ROCCAT ROCCAT Lua:
 MOUSE_DPI=250@125 500@125 1000@125 1250@125 1500@125 1750@125 2000@125 250@250 500@250 1000@250 1250@250 1500@250 1750@250 2000@250 250@500 500@500 1000@500 1250@500 1500@500 1750@500 2000@500 250@1000 500@1000 *1000@1000 1250@1000 1500@1000 1750@1000 2000@1000

But measurements using mouse-dpi-tool (libevdev 1.4) give me different frequency readings (value set with the driver tool -> reported mouse-dpi-tool value):
  * 125 -> 166,7
  * 250 -> 333
  * 500 -> 1000
  * 1000 -> 1000 (a few times it reported inf)
DPI readings are OK though.

Patch for adding mouse DPI data for Roccat Lua mouse
Comment 2 Blaž Tomažič 2015-04-03 20:33:02 UTC 
Probably I wasn't quite clear what I was trying to achieve with my bug report, sorry about that.

I would like to add Roccat Lua mouse DPI data to hwdb/hwdb/70-mouse.hwdb. I've attached a patch for it.

NOTE: I had different frequency readings with mouse-dpi-tool than the specs and mouse tools advertise (details in previous post). The values in the patch are as reported by manufacturer.
