If it makes it easier, i've backported those two patches into a PPA build on top of what's already in Ubuntu here: https://launchpad.net/~superm1/+archive/ubuntu/lp1574079
The version with those two patches is 0.7.0-0ubuntu4.2~lp1574079.2. Richard, I don't think there is anything else strictly needed that wasn't already part of 0.7.0's xenial release. -- 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/fwupd/+bug/1574079/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
