What version of the software are you running?
There is a common problem with the TrackIR v. 5 software regarding USB power. If you have too many things plugged in to your USB ports (even if they are powered remotely, like a USB hub), the Track Ir software drivers will fail and drop the device.
An instant fix is to just unplug it and plug it back in into a different USB port and unplug any unused USB devices.
A better fix (if you're using a Track Ir 4) is to roll back the software and drivers to the last 4.x version.
If you are using a 5.0, you're stuck. Just keep checking in with Natural Point for updated drivers.
