Hi  Infidel365,

Welcome to the Community,

In Device Manager is the Webcam getting detected under Imaging Device? Do you see anything listed with yellow question mark under Other Devices?

Did you update your system BIOS before upgrading to Windows 8?

Thank You

Yes i do see yellow question marks under the other devices drop down and yes i did update the bios before upgrading to windows 8. think i need to re install windows 8 again?

May I know what is listed with yellow question mark under other Devices?

If Webcam is not listed in Device Manager under Imaging Device then try installing Webcam Central From this link below: lt.dell.com/.../lt.aspx

After installing reboot the system and try to use the Webcam by accessing Webcam Central application.

If it still does not work then,go back to Device Manager and check if the webcam is getting detected.

3 Base System Devices and 2 unknown devices and i dont see a imaging devices on my device manager.

Looks like you have not installed the Chipset driver after upgrading to Windows 8.

Try installing Chipset drivers:

Intel Chief River QS77 Chipset : lt.dell.com/.../lt.aspx

JMicron Card Reader : lt.dell.com/.../lt.aspx

After installing the above two drivers,reboot the system and install the Webcam driver from my previous reply.Access Device Manager  to check if Webcam gets listed and also confirm if you still see Base System Devices and unknown devices under Other Devices.

the unknown devices are still there and the webcam is still not there and i installed all 3 drivers

Access Device Manager,right click on Unknown Device,select Properties,click on the “Details” tab and post back the Vendor and Device Id’s(“VEN_xxxx” and “DEV_xxxx”. These two things are you Vendor and Device Id’s).For example PCI\VEN_10DE&DEV_03D1&SUBSYS_14041565&REV_A2.

on one it says:

ACPI\VEN_SMO&DEV_8800

ACPI\SMO8800

*SMO8800

and on the other one it says:

USB\DEVICE_DESCRIPTOR_FAILURE

Hi Infidel365,

Try installing this ST Micro Free Fall Sensor Driver : lt.dell.com/.../lt.aspx

If the Webcam still does not get detected,reinstall Windows 8 and then first reinstall the ST Micro Free Fall Sensor Driver,followed by Chipset and then Webcam Central driver.

Let me know how it goes.

This solution worked for my scan snap (scansnap) scanner.  I had tried an s510 and an s300 without success.  I did notice in my device manager that my webcam was also listed under imaging devices also with a yellow exclamation.  So, I thought that maybe whatever drivers ran the webcam may also be used by the scanner.  Alas yes.  After installing the 3 axis fall driver, my webcam came online and after a reboot I finally got the scanner software to see the unit and remove the circle cross from the icon.  It is now scanning properly.  Hope this helps anybody who has had the same problem with their scansnap.
