FaceTime HD camera does not work properly on Boot Camp

On a 2018 rMBP, the drivers look like

Your Camera is a UVC (USB Video Camera) device. Do USB devices work properly on your Mac when booted in Windows?

I get a different version.

<ProductManufacturer>Apple Inc.</ProductManufacturer>
<ProductVersion>6.1.6813</ProductVersion>
<ProductCode>{FCFFE6B6-BAE8-490E-88D0-097A9DA1C43D}</ProductCode>

This is the log using Brigadier.

Can you check your Mac Model Identifier in About This Mac -> System Report -> Hardware?

Can you try to run a SMC Reset and check?

Can you check Windows Device Manager for any unknown devices?

Can you check your BC drivers USB and provide the Product Version from Bootcamp.xml file? Have you tried to re-install BC drivers?

The disk uses USB3.1 (I assume no USBc). You WiFi and BT should not be an issue.

Can you check the current draw for this device on the macOS side?

Does your Camera app have issues, with and without this disk being connected?

What is the year/model of your Mac (do not post the serial number)?

Can you a screen shot the Driver tab?

Yes, almost all USB devices work great when Mac booted in Windows except my external hard drive.

Nice.

When the hard drive is plugged on Mac booted in Windows Wi-Fi and Bluetooth turn off. I was told in the local service center that this drive consumes a lot of energy and there is not enough power to supply Wi-Fi and Bluetooth adapters.

This is incorrect. You can see the charging needs in About This Mac -> System Report -> USB. What type of a drive do you have? Does it have an external power supply?

It is in the BC drivers package. See Download and install Windows support software on your Mac - Apple Support for reference.

Before writing this post, as I mentioned before, "I tried to reboot in Mac and use the Bootcamp assistant to download another, more up-to-date copy of the windows support software.

Normally, the drivers are updated using Apple Software Update in Windows, after the initial installation. It is very rare to get an updated BC drivers package, which differs from the original used during the installation of Windows.

Then I rebooted into Windows and updated Boot Camp software from the USB device. It did not help. The camera still shows black screen and the OS "Windows" tells the camera works fine."

I do not have a 2017 MBP, but my test on a 2018 MBP works. Hence my question about the version of drivers. The drivers are the same, so we just need to verify the Product version from the XML file.
