Logitech USB Webcam not working after Catalina update

[johnap987]

I recently updated all my rigs to Catalina, I have in two of my computers a USB Logitech webcam to take pictures of clients using a small Automator app. After Catalina update Automator is not able to show any video from the webcam, when I clic on the Camera button the webcam's led turns on, but no video is displayed. Tried it with Photo Booth and video shows from web cam for a few minutes; but after a while it only shows a black screen showing "camera not connected". I have tried different USB ports without any positive results. Every thing else seems to be working fine. I can actually see the camera detected on System Report. Any ideas or suggestions?

Do you have USB power injection and have applied one of the proper USB 15 port limit fixes?

Thank for your reply. I haven't done none of that, at least that I am aware of. May you point me in the right direction?

Applied patches described at https://www.tonymacx86.com/threads/macos-catalina-10-15-0-usb-port-limit-removal-patch.285098/
Same behavior. Found out that if I have the automator capture screen active, and I start Photo Booth, I get video on both automator capture module and Photo Booth. I discovered this before patching USB port limits; after patch I got the same results.

[Guide] USB power property injection for Sierra (and later)

Summary It appears that Sierra has changed how USB power properties are set. In prior versions, we have injected AAPL,current-available, AAPL,current-extra, AAPL,current-extra-in-sleep, and AAPL,max-port-current-in-sleep directly on the XHC/EHCI ACPI objects. In Sierra, these appear to be...

Went through both guides, made a personalized USB SSDT, IORegistry Explorer only shows the ports I left in SSDT, removed port limit removal patch; but I can not get the usb camera to work with automator. Photo Booth does work, even FaceTime but not automator.
