Im using a logitec webcam for notebooks deluxe, I want to know why on some sites, I cannot go cam to cam with other host, they don't see or hear me. I haven't tried skype, but cam works fine with windows 7, but i rather use ubuntu, much faster video with webcam. Can someone please help me, does it work for all sites or not??
Sites using flash player as a base will will report some issues or bad experiences (compared with MS Based Systems).
I would suggest you to take a look at the solutions suggested on the answers to the list of questions at the end of this, in order to get a clue on where to start and probably try it yourself, which may improve your experience using your webcam in certain sites.

In my experience with this issue, Flash Player is experiencing some kind of problem to handle several video sources (which may not be your case). In my computer I have several video sources, and somehow it seems that Flash Player can reach the TV Tuner but is having problems to acquire images from the USB devices.
In order to solve this problem I have tried two tricks that I share to you not as a solution for your issue but as an alternative. The usage of the FlashCam Project or the Webcam Studio. Both them will drop a virtual device into your Flash Player device's list which will be easy handled.
In this answer: https://askubuntu.com/questions/53495/flash-crashes-on-enabling-webcam/53615#53615 I have previously documented this situation and I hope you find it useful, pasted here for your convenience:
Based on my personal experience when using the Ultimate Edition DistroPlayer, fully documented here: http://forumubuntusoftware.info/viewtopic.php?f=66&t=4998&start=0 , and information that can be reached here: https://bugs.adobe.com/jira/browse/FP-204, you can use The Flashcam Project in order to gain access to your webcam via Flash Player.
I have tried this both in Firefox and Chromium/Google-Chrome and it works like a charm but I continue experiencing some issues with the stability of the Flash Player when it tries to gain access to my TV Tuner instead of the Webcam itself.
Another temporal solution that I find useful is the usage of the WebCam Studio for GNU/Linux, which will drop a bridge between your physical webcam and a virtual webcam that can be seen and managed by Flash Player.
However, you may experience some issues when using both these tools, anyway it's worth than expecting Flash Player to do what it seems it can't.
Give it a try, and please inform how do you manage this issue. I am yet interested on having the experiences of other people in order to fix my TVTuner/Webcam crashing issue.
However, these are my answers but answers from other people may give you an idea.
