Question Camera and Webcam Problem - Error: 0xA00F4243 ?

[paulbasel]

I had an older Logitech webcam that worked for years. Then one day, sometime in the last couple of months I noticed it didn't work in Skype (black screen). I tried to find the problem but couldn't. I thought it was defective and bought a new one. Same problem. I tested the new LogiLink LL1 with the camera app and received this error. I should point out that the microphone worked on the old one as well as the new one.

"Close other apps. It looks as though another app is already using the camera. If you need it, here’s the error code: 0xA00F4243 (0xC00D3704)"

I have an Asus M51AC Desktop PC running Win 10 fully updated. I uninstalled the old Logitech software and driver before installing the new webcam.

Here's what I have tried so far with no success:

​

- Ran Malwarebytes - clean​

- Windows driver up to date, no separate driver for this new camera.​

- Ran DISM tools and SFC, fixed a couple of problems. No change.​

- Switched the USB port to one I know functions properly. No change.​

- Device manager shows the "USB Live camera" functioning properly.​

- Disabled all apps at startup, rebooted, no change.​

- Camera access is on. Turned off all apps using the camera. No change.​

- Uninstalled the MS camera app and reinstalled it after a reboot - no change.​

- Ran system troubleshooter, no problems detected.​

- Ran Hardware and Devices troubleshooter, it returned "saskutil and sasdifsv don't have drivers". These are associated with superantispyware. Not important for this problem.​

- Registry: added Dword: EnableFrameServerMode, hex value 0 in the Windows Media Foundation\Platform. Rebooted, no change.​

- Used Process Explorer to find whether any programs were running that used the Physical Device Object name, in my new webcam the object name is: \Device\000000b2. Process Explorer found none even though I had the camera app open as well as the Skype video setting. Refresh frequently, nothing. I believe this process should at least find the two devices that were open and running.​

​

Any help greatly appreciated before I lose all of my hair.​

Click on the Windows key + I to open the «Settings».
Select "Applications and Features."
Locate the Camera and click on it.
Select "Advanced Options" and then "Restart".
Restart the PC.

Then check.

I figured it out after months of trying and sending it back to the manufacturer. I had the camera plugged into my powered USB 3.0 hub which was working fine prior to February. After plugging it directly into one of my desktop ports it works no problem. Unsure why it doesn't work on the hub however.
