Description Tom Hughes 2014-12-12 20:09:09 UTC 
Mouse DPI data for various mice I had hanging around:

# Logitech RX1000 Laser Mouse
mouse:usb:v046dpc046:name:Logitech USB Optical Mouse:
 MOUSE_DPI=1000@125

# Logitech MX310 Optical Mouse
mouse:usb:v046dpc01b:name:Logitech USB-PS/2 Optical Mouse:
 MOUSE_DPI=400@125

# Logitech M-BJ58 Optical Mouse
mouse:usb:v046dpc00e:name:Logitech USB-PS/2 Optical Mouse:
 MOUSE_DPI=400@125

# Logitech M100 Optical Mouse
mouse:usb:v046dpc05a:name:Logitech USB Optical Mouse:
 MOUSE_DPI=1000@125

Note that googling produces many claims that both the MX310 and the M-BJ58 are 800 dpi but they certainly don't measure that way with the test tool.

Let's use your measurements until proven otherwise.

I'm starting to suspect that Logitech mice with the same identifiers can have different DPI. I have a Logitech M100 which I measured as 806 DPI, which is 1000 DPI in our database.
