Perhaps a driver is missing?
Could it have an hidden camera?
(I am not paranoid.. and not sooo important)
Thanks for any advice!

No camera is on this dell e4310 of mine
Code:
$ ls -ltrh /dev/video*
ls: cannot access /dev/video*: No such file or directory
Forgot: then
look for video. If there. Look inside for name of camera.

If cheese isn't working on it, you might try installing guvcview and testing with it.
You might also run the dmesg command in a terminal and search the output for a reference to a camera. That command outputs a lot of data; you may be able to prune filter the output with grep.
Code:
dmesg | grep Cam <----or a variation thereof
On my other computer, over there ---->, that command told me that the camera is a uvc device.

Thanks all!
"Fn + F6" dont change anything in dmesg (before or after a modprobe).
After "modprobe gspca_sn9c20x", the output of dmesg see 4 added lines:
Code:
[ 2075.842682] Linux media interface: v0.10
[ 2075.861320] Linux video capture interface: v2.00
[ 2075.873419] gspca_main: v2.14.0 registered
[ 2075.877176] usbcore: registered new interface driver sn9c20x
BUT "lsusb" (nothing new there)
Code:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 003: ID 0a5c:217f Broadcom Corp. Bluetooth Controller
Bus 002 Device 003: ID 17ef:1003 Lenovo Integrated Smart Card Reader
"Cheese" and "guvcview" still say no device is found.
Still no "/dev/video".
Any new idea is welcome.

You might check if it's disable-able in the bios / uefi.

I had a look: in the BIOS menu "I/O Port Access", "Integrated Camera" is "enabled".
No differences noticed between UEFI or Legacy boot.
dmesg | grep Video
