Laptop webcam is not detected, doesn't show up in lsusb
I'm weirded out. I have an Acer Aspire 5515 series laptop which has a webcam built in. When I open Cheese, it says: "no device found". Camorama says: "Could not connect to video device. Please check connection".
Neither lspci nor lsusb contain any records that can be a webcam. It's almost like there is no webcam in the system at all.

Help.
P.S.: Well, I'm beginning to think that the webcam is simply physically broken. I see no other explanation for it not to show up in lsusb.
Check if you have a switch button and certify that the camera is turned "on".
This switch could be on one of the function keys (accessible by using the Fn key).
Or as a separate button in a row, near the power button.
well. I tried Linux Mint and Fedora and also Windows 7 but no dice - it's simply not being detected. Basically - as long as there is no webcam in lsusb output - you can be pretty sure that it's hardware issue as most webcams in laptops are actually wired up as USB devices.
So there - my webcam is physically dead.
Activating the webcam was indeed the answer :
my button looks like this : (MSI Leopard Pro)
