I have a USB serial device. In a Xubuntu 20.04 computer it works perfectly, but when connected into an Ubuntu 22.04 computer I have it does not create the /dev/ttyUSB0
, or any. The command lsusb
properly lists this device, and lsusb -v -s
prints this:

I have already tried several things, like the brltty thing, checking that my user is in the dialout group, etc.
