|Thanks Johnw, I've just completed your suggestion. In fact, sfc /scannow asked me for win XP SP3 cd and 2-3 times got a system repair.Also many thanks to mavis007, but there is no problem in driver or device detection. However I got your suggestion.|
But unfortunately webcam is not yet listed as resource in my computer task and "Add Device Wizard in Ctrl Pnl/Scanners & Cameras" doesn't run.
I've tried also to deactivate all kaspersky feature (firs off all the firewall) or run windows in safe mode but these are not the question. Also WIA service is set on "automatic": in fact in control panel "Scanners & Cameras" runs , but the sequential automatic wizard "add device" does not run, while until some time ago was right.
I want remember that webcam is OK, there is no problem with any program (logitech sw, skype, messenger, device manager, and so on). It's not a big problem if I don't' get webcam in my computer, but I only say: why now it isn't in "other" resources as time ago?. I connected another webcam (trust) but it had same issue.
The only thing changed, in fact, is that last week I got a heavy update (150 MB more or lass) from microsoft update (last was in February). Some was bad?
