wondering if this tool will help solve a problem

spavett commented 3 years ago

I have a new Dell XPS laptop with windows hello face recognition built in. I also have a Logitech Brio, and external monitor connected to a Dell Thunderbolt dock. I work with the laptop lid open so both cameras are available to the system. I find a pattern of functionality:

After a cold boot the first face recognition sign in will use the Brio - works fine
Subsequent sign-ins will use the Dell cam - works fine
Eventually through a day of coming and going the laptop will report a problem on the sign in page and I have to use the fingerprint device instead to sign in - works fine
Looking into the device manager a number of devices have reported a code 43 - some sort of unexpected issue - including the windows hello face recognition device. Windows says it has stopped these devices due to the error.
A warm restart doesn't rectify this - it seems to require a shut down and cold boot.
Note: The web cams can still be used in conf calls after windows face recognition stops working so it doesn't seem to affect the normal light optics, just the IR cameras.

I noticed that there was no way to specify which camera to use and wondered if some sort of race condition was present in windows hello face recognition where two cameras are present where eventually the sign-in process will bug out. Is this something you have encountered and does this switcher prevent it happening?

Hello, I have not experienced a similar issue with my combination (Surface Pro 4 and Lenovo 500 FHD Webcam) and have no idea what actually happens in your system. Said that, this app intentionally disables specified built-in camera when specified USB camera is connected. Naturally it may change your system's issue.

Actually, I have been working on the improvement of this app and almost finished. Logitech Brio is one of rare web cam models capable of Windows Hello but I don't know much. So I am interested in how it looks like in the OS. If you don't mind, could you execute following command line command and post the result? It will help to make this app compatible with that camera.

pnputil /enum-devices /class camera /connected

Thanks for the response. Since my initial post I tried disabling the integrated webcam and the system used the Brio for a few unlocks but then the devices stopped working again so it seems the root cause is elsewhere. Might be a thunderbolt issue as the Brio can use a lot of bandwidth with its 4k res and there always appears to be an association with system Thunderbolt Controllers stopping at the same time when things go wrong.

The Logitech Brio seems to come up in various classes but not under camera.

As you see there are two integrated cameras I have no idea why there are two. There's only one web cam in the laptop itself. The Brio comes up under Imaging Devices in Device Manager but this class appears to be called Image in pnputil

Thank you for the quick response. The results of PnPUtil are quite helpful. The two built-in cameras may indicate ordinary camera and IR one. I would like to ask one more test of Win32 API. I am interested in whether it is possible to tell the two built-in USB cameras and Logitech Brio are removable or not. Could you execute the attached executable file and post the result again?

spavett commented 3 years ago

Can you share the code for the exe?

emoacht commented 3 years ago

No problem. I made some clean up and post it at https://gist.github.com/emoacht/0afa084cf30123f121492ab26fb8174d I am deleting the executable file. So could you build it on your own and execute it?

Thank you for the results again. Logitech Brio (shown in 24) seems okay. But built-in cameras (shown in 9 and 20) are unexpected. They must not be removable. Quite odd. Anyways, It is great help to improve this app.

emoacht commented 3 years ago

Released updated version. It should work with the devices of your system. I am not sure it can solve your issue though.

emoacht commented 3 years ago

Any new development? If no, I will close this issue.
