Hello, I have installed win 7 HOME Premium in my netbook Acer ZG5 AOA 150. Everything works fine except that Win 7 keeps telling me that a device was not installed correctly and is unknown. This device is listed in BUS USB CONTROLLER. I googled the problem and came across with crystal eye webcam issues. I tried to reinstall drivers for webcam (Lite-on/Crystal eye) from Acer but nothing worked (drivers are only for XP). I tried the manual method for installing drivers, but the inf file were not found. Then I tried the setup method provided with drivers and at some point i am told to plug in camera which I cannot as same is built into netbook. :shock: I installed everest to knwo what hardware are inside my ZG5 but I could not found a reference for the webcam camera. And for Win 7, the built-in camera does not exists and is not listed as hardware. I formatted again my drivers and reinstall Win 7 a second time. But problem still there. I phone Acer and they told me that they do not support the upgrading of their netbooks!!! :x I really do not know what to do. Thanks a lot for your help.
