Chicony Usb 2.0 Camera Driver Download Xp

Hello my friends, I have a Toshiba L300 PSLB0E - 02D020N5 or serial number 78377148Q and I installed windows 7. I have problem with camera display when use skype or facebook call. It stays black with the cirkle moving like is loading to open but never open and not displaying images (this for skype and for facebook nothing display just the other people to whom I make videocall i see but not my self neither they can see me). I doubt maybe driver has the problem. In Device Manager it shows that camera exist and says that it is Chicony USB 2.0 Camera. The driver is installed automatically by windows setup and even is updated but I can not find the driver of my model in Toshiba website and nowhere to try re-install if is the problem of driver. I don't know what to do more after lots of googleingCan you help me in this case? Thank you very much, Afrim
