[Bug 874181] Re: brltty daemon prevents creation of ttyUSB0 device link
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.

[Bug 874181] Re: brltty daemon prevents creation of ttyUSB0 device link
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 uploader as well as my FTDI adapter that I use for uploading codes to other circuits. The same issue occurs on connecting other tty devices such as an xbee coordinator we use in our servers at our company. I don't know how this could be fixed, but ubuntu 22.04 broke everything by including this package by default. It wasn't happening in 20.04. Thanks for your help.

An easy solution, though, would be for Ubuntu to give brltty's udev file an earlier position in the udev rules file processing order so that the generic rule will take precedence. Then there'd only be a conflict if a brltty user also has one of those other devices. That could happen, of course, but it'd be far less common than all users being impacted by the current problem.

Let's deactivate BRLTTY default Please don't do that. It'd make way harder for blind people to use Ubuntu. But at the moment it's causing a much larger population of people have their USB serial devices stop working for no apparent reason. And many devices are implemented by USB serial interfaces, some people are quite likely to have - GPS devices for example. brltty should only claim the USB serial interfaces used by Braille teletypes - although having been exposed briefly to this technology (supporting a blind staff member), I can imagine many are just 'write only' serial devices and thus undetectable. The modern ones probably use the SAME usb to serial chips that other non Braille devices also use, interfaced to the older 'write only' back end. As it stands, a much larger population are finding their GPS logger doesn't work, their 'ICE debugger' doesn't work, their home automation interface doesn't work, etc, etc. There are a truck load of USB devices out there that are implemented via a USB-serial bridge chip. The only compromise I can see is to use brltty during the install process so a blind user can install and throw up a question asking 'do you need Braille tty support ?' and hope most sensible sighted people will say no. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874181 Title: brltty daemon prevents creation of ttyUSB0 device link To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/874181/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 874181] Re: brltty daemon prevents creation of ttyUSB0 device link
I think it's usb 2. I'm not a Linux developer, so below is part of the kernel log showing the problem.

[Bug 874181] Re: brltty daemon prevents creation of ttyUSB0 device link
If it will help...the USB device from the ham radio serves two purposes: 1) Audio input and output. There was no problem with this. 2) Control of the radio through commands sent through the USB port. This was not working until I uninstalled brltty. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874181 Title: brltty daemon prevents creation of ttyUSB0 device link To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/874181/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 874181] Re: brltty daemon prevents creation of ttyUSB0 device link
I'm seeing the exact same thing with an Icom IC-7200 amateur radio tranceiver. Removing brltty resolved the problem, but I really think the default configuration should be to not run brltty. This took me quite a while to resolve after an upgrade from 11.04. I even did a clean reinstall of 11.10 thinking that maybe something went wrong with the upgrade. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874181 Title: brltty daemon prevents creation of ttyUSB0 device link To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/874181/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 874181] Re: brltty daemon prevents creation of ttyUSB0 device link
Removing the brltty daemon fixes this. Unless you really do use a Braille tty of course. If the software actually finds a Braille tty to talk to, it may then leave other usb tty devices alone. not being a Braille user I couldn't say. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874181 Title: brltty daemon prevents creation of ttyUSB0 device link To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/874181/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
