MCU-LINK vs. USB Webcam - Fighting One Another... weird

[dougshade]

OK... super weird.
When I plug in my FRDM-MCXN947 eval board into Windows (10), the system's Device Manager shows a new entry "Universal Serial Bus devices": MCU-LINK FRDM-MCX947 (r0E7) CMSIS-DAP V3.128. So far so good...

AND THEN...
When I invoke Microsoft Teams and try and use my Webcam... I get the message that my webcam is in use by another program... and so the webcam is unavailable.

I THEN...Unplug FRDM-MCXN947 (the MCU-LINK device drops from the Device Manager), and my Webcam then becomes available to use.

AND VICE-VERSA...
If I am using my Webcam first, then the FRDM-MCXN947 won't enumerate (never becomes available). Ugh... Cheers!   -Doug

Further details... from the Windows Device Manager...

MCU-LINK

VID 291

PID 3369

Something not so clean on Anker Web Cam

Device USB\VID_291A&PID_3369&MI_00\b&35c5aec&0&0000 was not migrated due to partial or ambiguous match.

Last Device Instance Id: USB\VID_05A3&PID_8830&MI_00\6&27d2624d&0&0000
Class Guid: {ca3e7ab9-b4c3-4ae6-8251-579ef933890f}
Location Path: 
Migration Rank: 0xF000FFFF0000F120
Present: false
Status: 0xC0000719

Note the VID & PID numbers for both devices, conflict here?... but I don't know what this means nor how to correct it.

Hello @dougshade 

1) Do you use one USB hub to connect the two devices? How about not use USB hub?

2) How about update debug firmware of MCU-link?
