Not known. In which situation does it happen and is reproducible?

Disconnecting and reconnecting doesn't result in error. I'll try a
reboot later.

After a reboot I still don't get the error (tryed connecting and
reconnecting the headset). Do you have any tests you want me to make?

Oh, if this is about replugging, I remember a long-standing bug in
usb-audio driver. Basically it happens when the device is reconnected
promptly during its device file is being opened. A kind of race
condition.
