usbhid.mousepoll

You need to edit your /boot/cmdline.txt by appending usbhid.mousepoll=2 to increase the mouse poll rate

https://wiki.archlinux.org/title/mouse_polling_rate.

There is a command called evhz.

How do I install it?

From what I understand the lower we set it the more CPU we use but the more accurate it can be if hardware can support it.

My Spinner can do 8MS is says on amazon.

I can't find lbusb device id.

My gut is telling me 2 is overkill. I think we should go with

usbhid.mousepoll=8

Here is CPU with no setting in cmdline.txt
