Blinking green LED drives me crazy. How can I stop it?

[GT-Force]

Hi all,

When my TrackIR4 is plugged in and the TrackIR software is not running, the green LED at the top of the device keeps blinking at a slow pace (and BTW, why does it do it/need to do it?). Since it's located right on top of my monitor, this drives me nuts. Is there a way to stop it from blinking (other than unplugging the USB cable, which is connected at the back of my computer inconveniently)?

Thank you.

No unfortunately there is no way to disable it. It is the hardware trying to check, and connect, with the TrackIR software

Hello GT,

when I got my TrackIR 4 Pro I was totally annoyed by this useless LED blinking.

Someone mentioned the MS tool "DEVCON" which I downloaded. It is just a small executable wothout any installation. With the help of a small batch file TIR is enabled only when you need it. First perform a serach for TIR with devcon:
C:\Programs\Tools\devcon find USB\VID_*

Find the entry for NaturalPoint Track IR 4 and use the value (ignore everything including and following the second backslash) and then create the three-line batch file (e.g "Start TIR.bat"):

C:\Programs\Tools\devcon enable "USB\VID_131D&PID_0156"
C:\Programs\NaturalPoint\TrackIR4\TrackIR.exe
C:\Programs\Tools\devcon disable "USB\VID_131D&PID_0156"

Create a shortcut for the batch file on the desktop and set its properties to "run minimized". From now on, instead of clicking the TrackIR icon on the desktop, just click on the shortcut for the batch file. This enables the TIR and then starts the TIR software. When terminating the TIR software, the TIR device is disabled and therefore no longer blinking.

Enjoy your blinking free monitor area

Best regards

This is a way to do it as well. Please note that the original program is only designed as a debug/development tool, use at your own risk.

I also want to disable the annoying blinking. When I disable TrackIR with devcon, the LED continues to blink, although TrackIR is deactivated (I have checked it in the device manager, it is deactivated and TrackIR does not work in that state). I am using Windows Vista and I used Administrator privileges in the command prompt. Any Ideas why this does not work?
