Hi @Jay and @Kingfriday, If this is continuously reproducible for you, it would be great to get some debug output from fwupd to figure out why this is happening. I unfortunately haven't been able to reproduce it using my USB audio device (Dell TB15 dock). Can you try to follow these steps to get a debug log?
1) sudo killall fwupd 2) sudo /usr/lib/x86_64-linux-gnu/fwupd/fwupd -v 2>&1 | tee fwupd_debug.log After you've captured the log, can you please report this to the upstream issue tracker? Ubuntu isn't carrying any patches that should cause this, so it should be reported upstream and fixed there. We can then backport the patch that fixes it to Ubuntu. https://github.com/hughsie/fwupd/issues -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574079 Title: USB audio device is not recognized after startup in 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1574079/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
