lsusb verbose output entry of microphone device not found by pipewire

Description of problem:
I'm unable to use my external USB PnP condenser microphone in Fedora 34 but can in Fedora 33 and RHEL8.

When I go to GNOME Settings -> Sound -> Input and select the drop down at Input Device, the microphone isn't an option.

Version-Release number of selected component (if applicable):
flathub org.pulseaudio.pavucontrol

How reproducible:
Always


Steps to Reproduce:
1. Plug in the mic, attempt to use an application that records audio
2.
3.

Actual results:
Microphone isn't found.


Expected results:
The microphone to work.


Additional info:

Here's the output of arecord -l which shows the microphone listed as [USP PnP Audio Device] 

$ arecord -l

I've attached the verbose output of lsusb for the device if that would be helpful.

Based on a suggestions from @wtay in #pipewire on freenode I attempted to run 'udevadm monitor' and 'PIPEWIRE_DEBUG=3 pipewire-media-session 2>log' ... in doing that, it worked and I don't know why. I killed that debug pipewire-media-session and launched a non-debug one and it works fine also. I've provided both of the logs as attachments.

I can't seem to reproduce this issue anymore so I'm going to close the bug.
