C920 Windows 7 64-bit Drivers Broken (?)

Hello all,

 

I just got myself an HD Pro Webcam C920. I downloaded the latest LWS 2.51 drivers. They install, but during the installation my webcam is not detected.

 

I attempted to manually install the drivers from the Windows device manager. The webcam shows up as "Unknown device". The device status is "The drivers for this device are not installed. (Code 28) ..."

 

When I click "Update Driver", Windows does find the Logitech C920 drivers (with signature). When I try to install them however, I get an error:

 

--------

Windows encountered a problem installing the driver software for your device

 

Windows found driver software for your device but an encountered an error while attempting to install it.

 

Logitech USB Camera (HD Pro Webcam C920)

 

An error occurred during the installation of the device:

 

The driver installation file for this device is missing a necessary entry. This may be because the INF was written for Windows 95 or later. Contact your hardware vendor.

 

If you know the manufacturer of your device, you can visit its website and check the support section for driver software.

---------

 

I am running Windows 7 64-bit, Service Pack 1. Everything works find except for the webcam.

 

I tried rebooting, uninstalling, and reinstalling the drivers multiple times. No effect. Something about these drivers is broken.

 

Your help is appreciated.

I believe I narrowed down the problem. It seems to be an issue with the signature/certificate of the driver.

 

Note that I have never made any changes to the security settings of my PC. In particular, I have never tinkered with certificates.

Re: C920 Windows 7 64-bit Drivers Broken (?)

I put my Windows installation in test mode (no driver signatures required). Same error. I thus suspect that the certificate error is a red herring. The real problem may be this:

 

!!!  dvi:                               Error: No INF AddService directives contained the flag SPSVCINST_ASSOCSERVICE
!!!  dvi:                               Error while installing services.
!!!  dvi:                               Error 0xe0000219: The installation failed because a function driver was not specified for this device

 

Seems like the INF file does not like my system or vice versa.

 

Btw, the webcam works just fine on my other Windows 7 64-bit machine, which is an old laptop that had LWS 2.40 installed back when it was still running Vista 64. So there is nothing wrong with the hardware.

 

Note that the previous message was printing the log files for the failed LWS 2.40 installation. I just tried another LWS 2.51 installation. The error logs are the same except for the driver versions, so I will spare you the dump.

Re: C920 Windows 7 64-bit Drivers Broken (?)

I managed to get the webcam to work, but not exactly the way I would have preferred.

 

1) I uninstalled all Logitech software

2) I unplugged the webcam

3) I configured the Device Manager to show unconnected devices

4) I uninstalled the webcam in Device Manager, deleting the driver

5) I manually erased all Logitech related files on my disk

6) I manually erased all Logitech related registry contents

7) Reboot

8) After reboot, Windows automatically installed a driver through Windows Update

 

The driver Windows installed for me works. Curiously, this driver appears to have the same version as the LWS 2.40 driver which would not work when using the Logitech installer.

Re: C920 Windows 7 64-bit Drivers Broken (?)

In my case, it's hardware problem. The cable for the C920 is a bit thin. It gives "USB device not recognized" message when connected to the front end of PC or extension cable. 

 

Connecting it to one of the back USB ports made a lot of difference. Driver install was then succesful

Re: C920 Windows 7 64-bit Drivers Broken (?)

I ran into the same problem with Windows 7 x64 and couldn't find an answer on the web. I hounded a logitech level 2 tech and was able to get the answer. 

 

I was missing USB.INF from c:\windows\inf. Once I added USB.INF the Logitech camera installed perfectly. Here is his email below:

 

------------------------------------------------

 

Here is a list of some common USB-related files, whose absence or damage will prevent the Logitech product from in-stalling properly:

 

USB.INF

KS.INF

WDMA_USB.INF

USBVIDEO.INF (for web-camera video)

WDMAUDIO.INF (for audio USB devices, such as a microphone)

 

They’re meant to be present in C:\WINDOWS\INF (which is often hidden unless you change the folder view option in explorer, as shown in figures 1 and 2; press the Alt key to show the menu-bar, click Tools and then Folder options…

You’d also want to uncheck the “Hide extensions for known files types” because it’s a pain! )

 

If these, or other, system files are missing or damaged, it is possible to copy them from:

A) another location on the computer (this involves searching for that particular file)

B) from another computer with the same operating system

C) from a known, trusted 3rd-party source like http://WWW.INFDUMP.COM/

Re: C920 Windows 7 64-bit Drivers Broken (?)

[ Edited ]

Im replying to your welcome post .  I have the same problem it seems with broken drivers.  My new 920 purcheed from a large concern in Bklyn., NY will not run.  But  the camera works fine on my friends computer installed with windows 7. however.

 

This is a brand new computer with a asusz87-pro. M.B..  It was assembled by  my friend who has experience assembling P.C.'s  I  have tryed everything to get the 920 to work on this units 64-bit system.  Including going to the device manager and the boot screen.

 

There is a flashing red light on the front of the unit.  I also had a problem with a number of virises and malware which caused the machine to run slow and the curser to lag while using the mouse.  I have taken care of virus problem since then though.  Used "Revo-uninstaller program and a purge at the anti virus software site.

 

I have until thursday to exchange and return the mother board.  My friend installed the processer with a no force; non pin type  configuration.  It was his first time for that.  Were getting a better magnification system to see if on of the M.B. pins might be bent.  Were thinking maybe that isboth  the red lite and camera problem.  A problem when we installed the processer.

 

It say the device is working properly on the device manager?

 

I downloaded the software for windows 7 from your Logitech site too.

 

If you have any inpute and/or help for me it would be much appreciated.
