As mentioned by Sebastien above, I have a smiliar issue which is blocking the use of the USB as serial port for use with Arduino. If this helps, my dist-upgrade log is available in another bug report if you want to have a look: https://bugs.launchpad.net/ubuntu/+source/ubuntu- release-upgrader/+bug/1969353
Based on the content, it looks to me like brltty was already there prior to upgrade and I also woudn't have used brltty during installation which was only done 2-3 weeks before upgrade. I also just did a fresh install in a virtual machine and brltty is also there. It looks to me like this package is a dependancy of ubuntu-desktop or similar through orca: $ apt-cache rdepends brltty brltty Reverse Depends: brltty-espeak xubuntu-desktop vanilla-gnome-desktop ubuntukylin-desktop ubuntu-unity-desktop ubuntu-budgie-desktop speechd-el brltty-x11 brltty-speechd brltty-flite orca ubuntu-desktop-minimal ubuntu-desktop for info, I did also check on a fresh Debian Testing install and the package isn't installed by default there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958224 Title: brltty claiming cp210x devices on 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/1958224/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
