Hello, I experienced some problems with Acer BisonCam builtin on Notebook. I tried to update packages to most updated (kernel, uvcdriver) but the problem occurs at the same way. When I use ucview application, sometimes it crashed when I try to initialize the cam. I found the device information as fully compatible at device list, but the name is different. When the problem occurs I have to remove and add again the module to work again. At terminal the application writes:
