Non-apple USB mouse tracking slowly This morning my (non-apple) USB mouse, a HyperX PulseFire, has suddenly started tracking slowly.

I've checked the mouse preferences and nothing has changed since Friday. I've also increased the tracking to max and it doesn't change.

I've done the reset where I hold down cmd + opt + p + r and no change.

I've manually increased the scaling and tracking to 5.0 and 15.0 respectively using the terminal commands below and no change.

defaults write -g com.apple.mouse.scaling 5.0
defaults write -g com.apple.mouse.tracking 15.0


I'm now out of ideas - anyone experienced something like this before?
Any ideas?
Tried increasing the DPI setting?


  The mouse's DPI setting is adjustable through the home-plate-shaped button behind the scroll wheel.
