My Zowie FK optical mouse (for gamers) came with a 1000Hz polling rate built-in. When I use the Mouse Rate Checker app, it displays polling rate up to 1000Hz, but its not static at 1000Hz - is that how it supposed to be? I think my Xbox 360 controller uses only 125Hz polling rate on my PC because when I use it to control mouse cursor within Windows 8.1, Mouse Rate Checker hovers around 60-110Hz... How can I make all USB ports use 1000Hz for all games in Windows 8.1 (all newest updates installed)??? In BIOS I disabled USB 3.0, USB legacy support, and some USB xHCI mode. I only left the raw USB 2.0 support in Windows. This actually reduced my USB driver latencies when I checked with LatencyMon. Now I just need to make sure all USB ports use 1000Hz polling. I saw some guides that talk about over-writing USB drivers - is that what I need to do? Could someone link me to the latest Windows 8.1 "hacked" USB driver?
