BTW, this is a big deal. I've already had over a dozen microcontroller students with this problem that upgraded to Ubuntu 22.04 LTS and could no longer program their Arduinos.
It also affects any amateur radio operators using FTDI USB to Serial adapters and I've had several of them call me when their adapters no longer worked after upgrading to Ubuntu 22.04 LTS. I filed a bug on brltty and the FTDI chips: Bug #1972030 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970408 Title: brltty package disconnecting ttyUSB0 used for Arduino To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/1970408/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
