lomoco

lomoco (Logitech Mouse Control) can change the CPI resolutions on some Logitech mice. To change cpi resolution for Logitech mice, install the package:

emerge --ask --verbose lomoco

The run lomoco -8 to change the resolution to 800cpi.

If you want to make the change permantly, create the following file:

File: /etc/udev/rules.d/55-lomoco.rules
BUS=="usb", SYSFS{manufacturer}=="Logitech", SYSFS{product}=="USB-PS/2 Optical Mouse", RUN+="/usr/bin/lomoco -8"

USB HID driver

The usbhid driver provides a method to change the polling interval. The mousepoll argument accepts an integer, the interval between mouse polls in milliseconds:

File: /boot/grub/grub.conf

 options usbhid mousepoll=2
 

Afterwards run update-modules.
