Issues with C920, Skype for Desktop, ManyCam, and Windows 8

[ Edited ]

So I'm experiencing some odd behaviour with my C920 I just purchased.

 

It doesn't work in Skype for desktop, or manycams, but works fine in Keylemon and the Camera app in windows 8 metro.

Re: Issues with C920, Skype for Desktop, ManyCam, and Windows 8

So following this up with some additional information.

 

The webcam doesn't work in the Logitech Webcam Software, it has the same issue as Skype, it just doesn't seem to detect it.

 

I followed this set of instructions I found in a similar post but subsituated the C270 for the C920 to see if I could get LWS to see the webcam, but no luck. Keylemon worked with it immediately. The Camera tile that comes with windows 8 metro detected it fine as well.

 

1. Open the Device Manager, expand the Imaging Devices section and verify if you have an entry for the C270. If you do, right click on it and select uninstall, if not continue with step 2.

2. Unplug the C270 from the computer.

3. Go to Add or Remove Programs and search on the programs list for the Logitech Webcam Software and Logitech Webcam Controller. If you find them please remove them, if not continue with step 4.

4. Download the LWS from the C270 Downloads Page and save the file.

5. Do a clean boot.

6. Install the LWS from the file that you previously saved. Plug in the C270, when prompted by the on-screen instructions.

7. Try to make a video and to take a photo using LWS, Skype may not be available in clean boot mode.

8. Restore your system.

9. Check to see if the issue persists.

Hello Fireslide-,

 

As I understand it, you have already tried a clean install, but the C920 is still not detected by Skype nor by the LWS. Please keep in mind that the only software version that supports this webcam on Windows 8 is 2.80. If you went through the troubleshooting, and installed a different version, we would need to try again, but this time please install LWS 2.80.

 

If the issue persists, it would help a lot to know how is your webcam listed in the Device Manager, and if the issue is occurring on multiple computers.

 

I'm looking forward to your reply Fireslide-; I hope that we can figure this out soon.

Re: Issues with C920, Skype for Desktop, ManyCam, and Windows 8

I installed LWS 2.80 when I performed the clean install.

 

The webcam is listed in device manager, this data was copied from the device information tab.

 

=== Start of device information =======================
Device name: Logitech HD Pro Webcam C920
USB Vendor ID (VID): 0x046D
USB Product ID (PID): 0x082D
USB Revision (BCD): 0x0011
Firmware Version: 7.5.1023
Firmware CRC: 0xFFFF
EEPROM Version: 0.0
Sensor Type: 4.38
Driver Version: 13.80.853.0
=== End of device information =========================

 

Testing on a another computer with Windows 7. Installing LWS 2.51 it worked with no issues.

I suspect it's something to do with how Windows 8 handles permissions or access to hardware and Metro. 

 

Any more suggestions?

I looked through the LWSDebugOut.txt

 

I get a number of entries like this

 

.\DevExplorer.cpp
Line: 1502
SetupDevicesForMonitor: Failed to open a Device... Ignoring...

 


followed by this

I don't mean to bump this, but would anyone be able to suggest what I can try next?

Found the problem.

 

Asus AISuite III and AiCharger+ was making the USB ports in desktop mode unreliable or something.

 

This patch fixed it up
