Mouse polling

Mouse polling can be defined through the kernel module usbhid, using the mousepoll parameter with any of the following values:

Value	Polling rate
10	100 Hz (default)
8	125 Hz
4	250 Hz
2	500 Hz
1	1000 Hz

How to find out the current polling rate

Use this command to get the current polling rate:

cat /sys/module/usbhid/parameters/mousepoll

Testing different polling rates

This command can be used to test different polling rates (replacing N with a value from the table):

sudo modprobe -r usbhid && sudo modprobe usbhid mousepoll=N

Making the change permanent

Append the following lines to /etc/modules (replacing N with the desired value):

-r usbhid
usbhid mousepoll=N

This change will be live after rebooting.
