Mouse polling not working

I've followed the instructions here:

https://wiki.archlinux.org/index.php/Mouse_Polling_Rate

Since modprobe.conf doesn't exist, I added options.conf to /etc/modprobe.d instead and put:

options usbhid mousepoll=2

Inside the file.

However, when I run the evhz tool provided, it shows: Logitech USB Receiver: Latest   125Hz, Average   113Hz

It's still running at 125hz, what else do I need to do to?

If I run

cat /sys/module/usbhid/parameters/mousepoll 

it correctly reports the value from /etc/modprobe.d/options.conf, is it a problem with the evhz tool?

Re: Mouse polling not working

Last I heard, if usbhid is a built-in module in the kernel, then the parameters must be specified in the kernel commandline instead, e.g.:

APPEND root=PARTUUID=000blah rootfstype=ext4 usbhid.mousepoll=2 apparmor=1 hpet=disable clocksource=tsc processor.max_cstate=1 vmalloc=384M acpi_os_name="Linux" pcie_ports=native pcie_aspm=force

To check the commandline:

cat /proc/cmdline
