Created attachment 114854 [details] [review] Patch for adding mouse DPI data for Roccat Lua mouse
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.
