Problem: Kernel PnP 442. My USB Mic doesn't work

[MarinaRama]

I have Windows 10, updated the last version.


I was using with no problem an USB Mic (ZOOM H2). As soon as I installed a Focusrite Sound Card, I couldn't make my H2 work anymore.


ZOOM H2 drivers are Ok, Windows still recognice it when I connect the H2 Mic, all sound settings are fine. But the sound is not recieved by windows.


The only strange thing I could discover is:

When I see the "Event Viewer" related to the H2 there are three events:


Information 28/09/2020 05:42:57 p.m. Kernel-PnP 410 None
Information 28/09/2020 05:42:57 p.m. Kernel-PnP 400 None
Warning 28/09/2020 05:42:57 p.m. Kernel-PnP 442 None

About this last one, it's written:


Device SWD\MMDEVAPI\{0.0.1.00000000}.{8c8d49c0-62c7-498d-93a1-8932ec99f7d0} was not migrated due to partial or ambiguous match.
