Here is the corresponding dmesg output:
[10909.673158] usb 5-2: new full-speed USB device number 2 using uhci_hcd

And bam, the thing switched itself off again.
So:
sudo modprobe -r snd-usb-audio
[10924.329105] usbcore: deregistering interface driver snd-usb-audio
Now switching the thing on again:
[10927.969127] usb 5-2: new full-speed USB device number 3 using uhci_hcd
[10928.114284] usb 5-2: config 1 has an invalid interface number: 3 but max is 2

[10933.216316] usb 5-2: 1:1: cannot get freq at ep 0x2
It's still on without problem. So
sudo modprobe snd-usb-audio
[10938.345556] usbcore: registered new interface driver snd-usb-audio
and it's still on.
And
cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfe020000 irq 31
1 [Audio ]: USB-Audio - USB Audio
ACTIONS USB Audio at usb-0000:00:1d.0-2, full speed
And I can actually use it (it's hw:Audio ).
So what can I do to get this fixed upstream in a manner where I don't
need to temporarily remove the usb-snd-audio device for plugging the PC
Bamster in?
