I can confirm this fwupd issue for a different USB audio device, a
PreSonus AudioBox 1818 VSL.
When I connect the card I get this in /var/log/syslog [1] [2]:
Apr 24 15:41:47 yogamme kernel: [ 34.958299] usbcore: registered new interface driver snd-usb-audio

...
Running `alsamixer` and selecting the USB sound card causes alsamixer to
abort with a "protocol error".
If I do `sudo killall fwupd` and reconnect the USB sound card,
everything works fine. It seems that fwupd is interfering with ALSA
gaining control of the sound card.
[1]: My Thinkpad Yoga 14 laptop has USB 3.0 ports, but one can force them to behave as 2.0 ports via a BIOS/UEFI setting. The syslog excerpt is for USB 2.0 mode; in 3.0 mode an additional log message mentioning "URB transfer length is wrong, xHC issue?" appears among the usb_set_interface messages.
[2]: The gnome-software warning *is* related to fwupd - https://github.com/hughsie/fwupd mentions GNOME software as "the only graphical frontend available" for fwupd at present.

Title:
USB audio device is not recognized after startup in 16.04
Status in alsa-driver package in Ubuntu:
Invalid
Status in fwupd package in Ubuntu:
Confirmed
Bug description:
Hi @all,
I used the same USB audio device in all previous Ubuntu versions
(Focusrite Scarlet 2i2). It is supposed to be class compliant and
works an all distros flawless (even RPI2 and OSMC). After upgrading
from 15.10 to 16.04 it stopped to work: after start-up it does not
show up as an audio device at all (also not recognized by aplay -l). I
can workaround this by unplugging it and plugging it in again after
Ubuntu booted up (strangely 2 times unplug/re-plug). After 2nd time
plugging it in again it shows up and works great without any further
issues until next restart.
Maybe worth to note that I recognized today that fwupd uses
continuously 100% CPU load, so I just killed it today. My Hardware
(Main-board/CPU) is a bit older (Intel E8400), so could probably be
some compatibility issue...
regards,
Tobias
