This is currently preventing me from using a Digirig Mobile amatuer
radio interface device, which uses the 10c4:ea60 Silicon Labs CP210x
UART Bridge. Pop_OS depends on brltty so I can't remove the package.
However, I was able to follow comment #2:
Edit /etc/brltty.conf, and add line:
```
Absolutely. If we are unable/unwilling to patch up or remove the
offending package, would it be possible to at least mark the Arduino
package “incompatible” with brltty (and vice versa)?

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
Yes, that’s the one. Does it work when you remove the brltty package? Do
you remember installing it?

Title:
brltty package
that's a nice workaround. I still think that there is something odd
going on with the brltty package though as it shouldn't be disconnecting
connections like this.
