I can confirm that this exist in ubuntu 22.04. I stumbeled on it when
trying to connect ESP32 via usb. As others have written in this thread
the short term fix is to remove brltty, e.g. sudo apt remove brltty.
However that is slightly annoying.

I just run into this issue after upgrading from 20.04. This is breaking

Linux is finally getting Windows users to experiment with switching over
to Linux. Many of those new users are natural experimenters anyway.
That is why most of the complaints on this thread include ham radio
operators that are using the serial USB connection for some other piece
of hardware.
It seems that brltty is now installed by default for Ubuntu 22.04 and
this bug prevents USB to serial adapters from working correctly out of
the box. Don't give nay-sayers a reason to no upgrade/use Ubuntu 22.04.

Yes, unfortunately there is no way to fix it in that case. The udev

Brltty doesn't run, unless either it is enabled in /etc/default/brltty,
