Webcam not detected in cheese, also not listed in lsusb

Question

I have dell inspiron n5110 laptop with windows 7 and ubuntu 14.04 installed in it. Webcam works fine in windows. But in ubuntu , cheese shows "no device found". Here is my output of lsusb:

Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 0781:5567 SanDisk Corp. Cruzer Blade
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 004: ID 0cf3:3005 Atheros Communications, Inc. AR3011 Bluetooth
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I tried installing the drivers by typing :

sudo apt-get install cheese build-essential linux-headers-`uname -r`

Still the problem remains the same. I tried sudo chmod 777 /dev/video* It says:

chmod: cannot access ‘/dev/video*’: No such file or directory

Now I tried all available solutions but no had luck. Currently it seems that this is an unsolved problem.

Answer 1

Uninstall cheese and config files:

sudo apt-get --purge remove cheese

Reinstall cheese:

sudo apt-get install cheese

Reboot your computer

This works perfectly for a Dell Notebook using Ubuntu 16.04

Answer 2

• Open up your terminal application (Ctrl+Alt+t).

• Open your grub configuration file for editing as root:

  sudo nano /etc/default/grub
  

• Change the line that reads:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash
  

  to read:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi="
  

• Save the file and exit the text editor. (Ctrl+o, Enter, then Ctrl+x)

• Update grub:

  sudo update-grub
  

• Restart/Reboot your computer.

Answer 3

I know maybe a stupid answer... If you have dual booted Windows and Ubuntu in your system and if accidentally you disabled camera (F6) in Windows (atleast for MSI Laptops) it affects Ubuntu as well. So just go back to Windows and enable it, and hopefully it works now.

Answer 4

I saw this post from LinuxMint forum

• Unload the uvcvideo module

  sudo rmmod uvcvideo
  

• Reload the module with the quirks parameter set to 0x100

  sudo modprobe uvcvideo quirks=0x100
  

• Cheese app still crash.

• Try at http://www.testwebcam.com/
• Allow when Google Chrome asked.
• Enable when Flash plugin asked.
