brltty won't be reinstalled on upgrades, removing it is a perfectly
valid option.
I linked a relevant Debian bug.

This is still an issue in Ubuntu 22.04. I solved it by using apt to
remove brltty. Unfortunately this is likely to be temporary as an update
will reinstate it.

Same issue here with FTDI device in 22.04 LTS
[0.102175] printk: console [tty0] enabled
[8.398040] usb 1-2: FTDI USB Serial Device converter now attached to ttyUSB0
[8.936936] usb 1-2: usbfs: interface 0 claimed by ftdi_sio while 'brltty'
sets config #1

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.

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
@Akos, do you mean 22.04? if so the ticket about the recent version
issues is bug #1958224

Title:

I just run into this issue after upgrading from 20.04. This is breaking
a lot of things for me. It seems that "apt remove brltty" resolved the
issue for now, but it should work out of the box as it used to.

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.
Thanks!

I have the same problem with FTDI serial to USB converter after I
upgraded to jammy.

I fear this is a Wontfix issue, as priority is given to the out-of-the-

I just came across this in Jammy (for the first time) as well. I have
two icom ham radio transceivers that use this chipset and the first one
detected IC-7300 was not usable until brltty was removed.
USB ID: 10c4:ea60
looking at device
Yes, unfortunately there is no way to fix it in that case. The udev
rules properly avoid starting brltty when the iManufacturer field is
changed from FTDI to the actual manufacturer of the device, but not when
it is left to FTDI.
