This issue also effects electronics hobbyist as I couldn't upload any code to my ESP32 controller because the port keeps disappearing. It is that after I found the dmesg message about the brltty, I have realized something was wrong. I was checking my hardware because of it. I breaks my ESP32 uploader as well as my FTDI adapter that I use for uploading codes to other circuits. The same issue occurs on connecting other tty devices such as an xbee coordinator we use in our servers at our company. I don't know how this could be fixed, but ubuntu 22.04 broke everything by including this package by default. It wasn't happening in 20.04. Thanks for your help.
