SLATE driver can’t connect to base
The USB-Serial converter device shares the same vendor and product ID with some braille readers.
Because of this, the brltty program may claim the device, preventing its use by other drivers.
Solving this issue is as simple as removing the package using apt.
$ sudo apt-get remove brltty
