Dell Ultrasharp Webcam 4K WB7022: Green tint in video after update to firmware 0.0.9.1

Dear all,

yesterday the Dell Peripheral Manager prompted me to update the firmware of my Dell Ultrasharp Webcam 4k to firmware 0.0.9.1. That update failed initially but then worked. Since the update the video image is frequently having a heavy green teint. Not sure if that is a problem caused by the new firmware or if the update somehow crashed something.

I have a second WB7022 that runs on 0.0.8.1 and that works fine if connected to the same PC so I assume it must be the webcam that is corrupted and not the drivers on the PC.

Does anyone know you to obtain the older firmware and how to downgrade to it to see if that solves the problem?

Best regards

Tammo
