I am using Acer Aspire 5734Z-4725 model with ubuntu 14.04. The problem is I can't use the webcam. I use Cheese to test the webcam and it said "No device found".
I am new to ubuntu so a details instruction will be nice. Thanks in advance
If you know the model of the webcam try searching for a driver on their site, not sure if many providers do drivers for ubuntu.
Install UVC it might have your driver on it (http://www.ideasonboard.org/uvc/#download)
If you cant remember the model id you can verify it by using
lsusb in the terminal and verify that it is supported by UVC (http://www.ideasonboard.org/uvc/#devices)
