I have the same apc ups system
# lsusb |grep 51d
Bus 001 Device 002: ID 051d:0002 American Power Conversion Uninterruptible Power Supply
but do not have a usb microphone, just one connected to my sound card.

I've seen no impact on other usb devices, and see no indication of problems
in the provided journal or lsusb output.

If you boot with the UPS connected, and then connect the microphone, does it
work? Does it work if both are connected before booting?

Dang! I HATE when symptoms change/disappear...  Decided to retest and the issue is not present now. 

What wasn't clear the original report is that both USB microphones were affected; one is part of the webcam, and while audio was dead, video was fine.

Hmm...  the very last updated package was:
webcamoid-9.0.0-3.mga9.x86_64                 Fri 09 Dec 2022 08:18:45 PM EST

Will close for now.
