Title:
[USB-Audio - PX USB, playback] snd-usb-audio: probe of 2-3:1.0 failed
with error -22 after kernel upgrade

Bug description:
Bug report has been generated on a partially working configuration.
That allows ubuntu-bug to do more work.
USB-Audio Connection on Bowers & Wilkens PX Bluetooth Headphones
started working when upgrading kernel from 4.13 to 4.15 series. Then
it suddenly stopped working again on newer kernels. The bug report has
been generated on the latest working mainline kernel 4.15.7. All newer
kernels have some usb quirks in place, which should fix the playback
sample rates to 48 kHz. The quirk seems not to be working correctly
and hinder the audio system to recognize the USB-device as a sound
device.
The Headphones work on kernels before 4,15.7 when manually configuring
pulseaudio to a default samplerate of 48 kHz.
PX Headphones are on the newest firmware level.
