Aufnahme LED bei einer Logitech Sphere AF/MP ausschalten

This has been tested by me with Orbit MP and Orbit AF on WinXP using Logitech's 11.5 driver. I also tested on Win2K with various 10.x series drivers and it did NOT work. I think it's safe to say that in order to do this trick you need to be running driver 11.5 or higher, which also means you need to be running XP or Vista (in order to even install an 11.x series driver).
 
1) Shut down any/all software that is using your Orbit (Sphere) camera.

2) Unplug any/all Logitech cameras from your machine.

3) Run regedit, and navigate to this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}
 
4) Beneath this key you will find several (exact number depending on your setup) sub-keys. They will have names like "0000" and "0001" and "0002", and so on. Each one belongs to a different USB device. By examining the values contained in these keys you can figure out which one belongs to your Orbit. The value "FriendlyName" will contain an English description of the device to which the key belongs.
 
In the event that more than one of the keys has "FriendlyName" set to something like "QuickCam Orbit AF" then you should look at the DriverVersion values in each key to determine which one is the newest.
 
5) Once you have identified which of the device keys is the right one, look beneath it for a sub-key named "Settings". In Settings you should see a bunch of values, most of which begin with "LVUVC_".
 
6a) For AF Cameras: In Settings, find the value called "LVUVC_LEDControl". It will probably be set to 4. Change it to 0.
 
6b) For MP Cameras: In Settings, create a new REG DWORD value called LVUVC_LEDControl and set it to 0.
 
7) Repeat 4-6 for each of your Orbit/Sphere cameras.

8) Close registry editor, plug cams back in.

That's it. Next time you start your cam(s) with AbelCam (or any other program for that matter) the LED will not come on.
 
You could experiment with other values besides 0 and 4. 4 is "auto mode", i.e. the LED is on whenever the cam is capturing video. 0 is "totally disabled". Other values do other stuff that didn't seem very useful to me (e.g. 2 causes LED to blink while capturing).
