Dell XPS 15 (L502X) Webcam Won't Work!

     Received my Dell XPS 15 (L502X) back in mid-March, everything was working great (even the webcam).  Re-installed Dell Win 7 Pro 64-bit to remove bloatware and upon installing all drivers, the Device Manager shows a USB-connection error conflict.  All drivers, Windows updates and programs installed successfully except for the webcam.  Installed Dell WEBCAM Central software and it's saying "no webcam detected" and it's asking me to plug in a webcam. Also, I followed the correct sequence to installing all driver categories as per Dell's instructions below:

http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&docid=268873&l=en&s=gen

 

     The only issue I can conclude is that the incompatibility is due to the BIOS update I installed (revision A04) upon receiving the notebook.  Checking the version of the Quanta  H264 Webcam Driver, it currently shows 1.0.1404.1005, A00.  I didn't opt for the fancy-pants designer LCD so I don't think it's a physical connection issue. (could be wrong though)

 

    I tried "scanning for hardware changes" and "auto-installing best available software" from Device Manager but still no dice. 

Help!

Re: Dell XPS 15 (L502X) Webcam Won't Work!

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?

Did you recently install the operating system?

Re: Dell XPS 15 (L502X) Webcam Won't Work!

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

Re: Dell XPS 15 (L502X) Webcam Won't Work!

   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.

Similar to this image.
