Once again I'm in need of your wisdom, ESR.

Recently my Wheel Mouse Optical has been behaving oddly. Now I've used the wmo itself for years, but I only bought this particular one a few months ago.

What is happening is that when I stop moving it the rear red light switches off and the cursor (in windows) tends to disappear, only reappearing upon moving it again. It's almost acting like a wireless mouse low on battery. Ingame this manifests as mouse lag as if vsync is on.

I had previously overclocked my USB ports to 500 Hz to make the most out of the sensor, but recently reverted back to 125 Hz because Vista was being a pain and forcing me to disable driver signing on every startup. This issue has been occurring at both polling rates for the a past few weeks.

I tried wiggling the mouse cable to test if there was something loose there but I don't think that is the case. My guess is that it could be something to do with a power saving feature somewhere, but I don't know where to start.

So if someone has experience or ever heard of this problem your input would be much appreciated.

Cheers
