So basically for the past few months I've been running my different mice (Zowie EC1 EVO, Zowie AM, G400) at 1000hz with no issues whilst checking with mouserate checker.

One day I decided to use the 500hz option on the Zowie AM. Now for some reason, with any of my mice I cannot go back up to 1000hz, it just gets stuck on around 600hz. I've tried using all my USB ports, all of them are stuck at an average of 600hz.

I'm unsure if setting 500hz on the Zowie AM when i plugged it in (you can do so by holding down MOUSE5 whilst plugging it in) caused this issue. Don't think it's coincidence.

Anyway, I was just wondering where I could begin in trying to rectify this issue so I can run 1000hz again.
