accordboy23,

Try...

start, control panel, programs and features, Dell webcam Central, uninstall.

Restart your computer.

Rick,

   Yep, I uninstalled the v 1.3 Dell Webcam Central software, rebooted and installed v. 2.00.39 flavor. (Installed in C:\Program Files, not Program Files\(x86)) Still has the same problem.  I even updated the BIOS to the most recent release (A05).  I also tried uninstalling the USB 3.0 host controller (Renesas) and re-installed the Quanta H264 webcam driver (and then re-installed the USB 3.0 host controller driver after) to see if it was the priority of the USB driver installation that mattered.  Could it be a setting in the BIOS or something?

 accordboy23,

Did you recently install the operating system?

Rick

Here is what I have done since receiving the XPS 15 (L502X)

1.) Received it - Tested & confirmed computer works (even tested the webcam successfully)

2.) Re-installed Win 7 64-bit via my OEM Dell Win 7 64-bit disc to wipe out bloatware

3.) Downloaded new BIOS (revision A04 at the time) and successfully installed

4.) Downloaded & installed necessary drivers and Windows Updates - All successfully installed except webcam (USB Controllers - Unknown Device)

5.) Downloaded & successfully installed newer revision A05 BIOS

6.) Un-installed Dell Webcam Central software (1.3), rebooted and installed v2.00.39 (installed under Program Files, not Program  Files (x86))

7.) Un-installed USB 3 Host Controller (Renesas) & re-installed Quanta H264 Webcam Driver, then re-installed USB 3 Host Controller driver

8.) Issue still persists.....

 accordboy23,

Sorry for the delay, work.

2.) Re-installed Win 7 64-bit via my OEM Dell Win 7 64-bit disc to wipe out bloatware

When you installed Windows 7 (32-bit or 64-bit) did you install the desktop/notebook utility and the chipset drivers first? If not the rest of the drivers will fail to install. How to Download and Install Drivers in the Correct Order If you cannot find Windows 7 drivers, then try using the Vista (or XP) 32-bit drivers, for Windows 7 32-bit of the Vista (or XP) 64-bit drivers for Windows 7 64-bit and install the drivers in the Compatibility mode

Rick

   If you completely read my very first post, it specifically says I installed the drivers in the correct order as per the Dell link you posted. (which I also posted the same link) Also, as I said in earlier posts, I did find ALL Win 7 64-bit drivers and they all successfully installed; the webcam is the only device that is not being recognized by Dell Webcam Central and is showing as an UNKNOWN DEVICE conflict in the Device Manager.

 accordboy23,

Go to device manager and uninstall the unknown device, then restart your computer. The new hardware wizard will locate the device and if the drivers are there, will install it.

AlejoRoncarolo,

Does the webcam show up in the device manager under imaging devices? If not, contact Dell Tech Support.

Do you have the latest version of Skype installed? Try tilting the screen while using Skype? How about light pressure near the webcam?

Can you see anything here? Test Webcam
