[root@localhost ~]# mouse-dpi-tool  /dev/input/event7
Mouse Microsoft Microsoft® 2.4GHz Transceiver V1.0 on /dev/input/event7
Move the device 250mm/10in or more along the x-axis.
Pause 3 seconds before movement to reset, Ctrl+C to exit.
Covered distance in device units:     9837 at frequency 142.9Hz |       /^C
Estimated sampling frequency: 142Hz
To calculate resolution, measure physical distance covered
and look up the matching resolution in the table below
     624mm       24.59in         400dpi
     416mm       16.39in         600dpi
     312mm       12.30in         800dpi
     249mm        9.84in        1000dpi
     208mm        8.20in        1200dpi
     178mm        7.03in        1400dpi
     156mm        6.15in        1600dpi
     138mm        5.46in        1800dpi
     124mm        4.92in        2000dpi
     113mm        4.47in        2200dpi
     104mm        4.10in        2400dpi
If your resolution is not in the list, calculate it with:
    resolution=9837/inches, or
    resolution=9837 * 25.4/mm

Entry for hwdb match (replace XXX with the resolution in DPI):
mouse:usb:v045ep071d:name:Microsoft Microsoft® 2.4GHz Transceiver V1.0:
 MOUSE_DPI=XXX@142

[root@localhost ~]# cat /usr/lib/udev/hwdb.d/71-mouse-local.hwdb 
mouse:usb:v045ep071d:name:Microsoft Microsoft® 2.4GHz Transceiver V1.0:
 MOUSE_DPI=1000@142
[root@localhost ~]#

But no MOUSE_DPI shows up:

I'm running Fedora 23 beta.
The mouse is a wireless MS Laser mouse 6000 V2.0 with an USB dongle.
