Dear Maintainer,

Upgrading Debian kernel from 7.2.9+deb14-amd64 to 7.2.11+deb14-amd64 has caused my USB audio interface, a Behringer UMC404HD, to stop functioning, with the errors listed below.
Expected result: device initializes and functions normally for audio output.
Actual result: device seems to fail to initialize. Front lights flicker once per second and audio pops. In normal operation, this only happens once as device is powered on.
Reverting to kernel 7.2.9+deb14-amd64 fixes the issue.
