Cameras does not work with my T510i on WIn 7 64bit SP1

Question

Hi,
first noticed that Fn-F6 app say all the time that my built-in camera is used by another program (in fact it means just that it cannot access the video preview). Then bought USB camera from Microsoft and it appearad that any video camera connected to my T510i does not work!
Except Skype - all of them works fine in Skype.
As I further examined the problem is with the DirectShow rendering wrong filter graph when accessing any of the cameras registered in the system.
Error config:
Filter Graph:
[Integrated Camera (Przechwyt.)] --> [(Input) Sample Grabber]
[Sample Grabber (Output)] --> [(XForm In) AVI Decompressor]
[AVI Decompressor (XForm Out)] --> [(Input) Color Space Converter]
[Color Space Converter (XForm Out)] --> [(VMR Input0) VMR9]
Working config (I've made recovery and clean install with all windows updates):
Filter Graph:
[Integrated Camera (Przechwyt.)] --> [(Input) Sample Grabber]
[Sample Grabber (Output)] --> [(Input) Color Space Converter]
[Color Space Converter (XForm Out)] --> [(VMR Input0) VMR9]
As I have found about DirectSHow filter graphs are not pre-defined but are rendered by the system from the settings and codecs available.  It seeems that there is wrong setting somewhere (possible wrong grabber ouptut setting) that results in inserting unwanted AVI decompressor despite there is no AVI stream there (as I have checked AVI decompressor is quartz.dll which is windows default codec?). According to the graph that works at the output of the grabber there is MPEG2 stream which is correct as all the cameras reports that they have internal MPEG2 encoder (not AVI), which only after color adjustment of the stream is accepted by video renderer.
How to change or reset to defaults that?

From your previous post, it sounds like at one point you are getting the pop up that says "installing device driver software," correct?
If you are not getting this pop up in the lower right hand corner of you screen then I need you to:
1. Try a different USB port on your computer. Some computer USB ports are "touchy" and if you try a different one it will work. It all depends on the make of the computer.
2. Try a different USB cable. You might have a bad USB cable. Also, be sure that the USB cable isn't longer than 3ft long.
3. Go into your device manager and see what printers have been installed. They should be listed under "printers" or "other devices" You might have to go to view and check show hidden devices to see these on your computer. If there is a yellow triangle or question mark on this device then you have a conflict with your computer. This is something in your computer causing this and not the software download.
Keep me  posted.
