Public bug reported:
I can't use this device; it shows up in dmesg, but it seems that systemd
hangs when trying to use udev to configure it. The important message (I
think) is:
usb 3-1: 13:0: cannot get min/max values for control 2 (id 13)
AND, here is from syslog:
May 10 23:46:59 dude systemd-udevd[302]: worker [5911] terminated by signal 9
(Killed)
May 10 23:46:59 dude systemd-udevd[302]: worker [5911] failed while handling
'/devices/pci0000:00/0000:00:1a.0/usb3/3-1/3-1:1.0/sound/card3/controlC3'
May 10 23:47:19 dude kernel: [114738.341243] usb 3-1: 13:0: cannot get min/max
values for control 2 (id 13)
...
I tried to use alsactl to force an init of this card; the very long log
is attached.
