            Bug ID: 89743
           Summary: hwdb: mouse DPI data, Roccat Lua USB mouse
           Product: systemd
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
          Assignee: systemd-bugs at lists.freedesktop.org
          Reporter: blaz.tomazic at gmail.com
        QA Contact: systemd-bugs at lists.freedesktop.org

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 at 125 500 at 125 1000 at 125 1250 at 125 1500 at 125 1750 at 125 2000 at 125 250 at 250
500 at 250 1000 at 250 1250 at 250 1500 at 250 1750 at 250 2000 at 250 250 at 500 500 at 500 1000 at 500
1250 at 500 1500 at 500 1750 at 500 2000 at 500 250 at 1000 500 at 1000 *1000 at 1000 1250 at 1000
1500 at 1000 1750 at 1000 2000 at 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.
