[Desktop-packages] [Bug 1958224] Re: brltty claiming cp210x devices on 22.04
Concerning 1a86:7523, the udev rules file in ubuntu indeed seems to be
missing the manufacturer filter:
debian/brltty.udev.rules says:
ENV{PRODUCT}=="1a86/7523/*", ENV{BRLTTY_BRAILLE_DRIVER}="bm",
GOTO="brltty_usb_run"
while it should be:
ENV{PRODUCT}=="1a86/7523/*", ATTRS{idVendor}=="1a40", ATTRS{idProduct}=="0101",
ENV{BRLTTY_BRAILLE_DRIVER}="bm", GOTO="brltty_usb_run"
This needs to be fixed in the various ubuntu brltty versions, starting
from 6.4.
BTW, for 403/6001 I see there
Ubuntu disable those to avoid conflicts, https://launchpad.net/bugs/1958224
But the line with the manufacturer filter should *not* be disabled, it properly
filters-in the producer of the Braille devices.

This bug was fixed in the package brltty - 6.4-4ubuntu3 --- brltty (6.4-4ubuntu3) jammy; urgency=medium * Try to resolve brltty conflicting with generic serials (lp: #1958224) * debian/brltty.udev.rules, debian/brltty-usb-generic.rules, debian/brltty.examples: - split the generic identifier udev rules to a separate rule which is going to be distributed as an example but not installed by default. Those rules are needed by some braille readers to work but conflict with cp210x and FTDI serial ports. Those special devices had required manual setup in Ubuntu since 2011 and were only added back to the default configuration due to a merge error. * debian/brltty.templates, debian/brltty.postinst, debian/rules: - when upgrading from a version that provided the generic rules prompt the user with debconf to ask if those should still be installed. The default answer is yes to avoid accidentally regressing users with a such braille reader configured during the upgrade. If you don't use a brailler reader you should answer 'no' to avoid having the service blocking access to other devices.

Hi Steve, would you he able to describe how the patch worked Vs current behaviour? If we can’t touch the package, can we remove it from standard install (like in Debian) to minimise the number of people impacted and/or make it incompatible with every other package which might be incompatible with it (such as Arduino) so people get prompted to removed brltty if it is installed - include special warning if you feel it’s needed)? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to brltty in Ubuntu. https://bugs.launchpad.net/bugs/1958224 Title: brltty claiming cp210x devices on 22.04 Status in brltty package in Ubuntu: Fix Committed Status in brltty source package in Jammy: Confirmed Bug description: * Impact The brltty udev rules are claiming generic devices IDs which makes some other devices like Arduino cards not able to interact with the serial port anymore * Test Case Try to use an Arduino over a cp210x or FTDI serial port, it should be able to talk to the computer * Regression potential There are some braille devices on the market using generic IDs which are going to stop working out of the box.

[Desktop-packages] [Bug 1958224] Re: brltty claiming cp210x devices on 22.04
I understand the importance of fixing this conflict, and I agree it's bad behavior on the part of the hardware manufacturer that retail devices were shipped using these generic USB IDs, but the consequence of the proposed SRU - disabling the use of brltty on the USB ids in question - is that a blind user who uses one of these devices, who has successfully installed Ubuntu and has a working system, will on the installation of this SRU have their only accessible tty device rendered inoperable. That represents a CRITICAL regression for the users in question. It effectively bricks their machine and requires the user to rely on a sighted person (who is also Ubuntu-knowledgeable) to get it working again. So I am rejecting this SRU. It's unfortunate that this wasn't caught before release, but now that support for this hardware is present in the release, we can't be bricking blind users' systems to enable other cp210x devices. We'll need to find some other path forward. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to brltty in Ubuntu. https://bugs.launchpad.net/bugs/1958224 Title: brltty claiming cp210x devices on 22.04 Status in brltty package in Ubuntu: Fix Committed Status in brltty source package in Jammy: Confirmed Bug description: * Impact The brltty udev rules are claiming generic devices IDs which makes some other devices like Arduino cards not able to interact with the serial port anymore * Test Case Try to use an Arduino over a cp210x or FTDI serial port, it should be able to talk to the computer * Regression potential There are some braille devices on the market using generic IDs which are going to stop working out of the box.

Thanks Samuel, I've uploaded the changes now.

> it's a bit unclear to me which entries there should be considered 'generic USB IDs'? They are marked "Generic Identifier", that's 0403:6001 10C4:EA60 10C4:EA80 > I also don't understand why those rules are debian specific See the diff between ./debian/brltty-udeb.udev.rules and ./Autostart/Udev/device.rules.in Note that in debian we use the udev rules *only* inside the installer. The current strategy in Debian is that in the installer we use udev rules to autodetect braille devices. But in the installed system we don't: when the user installs brltty, the user means that they have a Braille device and want to probe it, whether it uses a generic USB ID or not, i.e. we always start brltty > How does upstream handle the devices? When brltty is started it just always probes all devices. Its udev rules file always starts brltty, be it generic IDs or not. > We should stop installing brltty by default going forward That would align with the way it happens in Debian yes. Ideally the udev rules would be split so that the non-generic pieces get always installed to start brltty, and the generic pieces are installed only when necessary. That's a matter of actually spending time on implementing it. > we aren't going to respin ISOs on old serie for such changes and that wouldn't be a solution for already installed systems...

@Samuel so I was checking debian/brltty.udev.rules following your suggestion, but it's a bit unclear to me which entries there should be considered 'generic USB IDs'?

Thanks Samuel for sharing your expertise here! I would need to check why it has been historically installed by default but I would expect that's because we want the default installation as friendly as possible to users that need accessibility. Doing what Debian is doing is nice but gives an inconsistent result since it would depend of how the system was installed.

In this case, brltty appeared (or at least the device claim) after a dist-upgrade. I would have had no cause to use it through the initial installation.

Debian is installing the brltty package only when brltty was used during installation. Brltty gets started during installation either through the udev rules, or started manually from the kernel command line. The finish-install script just checks out /var/run/brltty.pid to determine whether a brltty is running. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to brltty in Ubuntu. https://bugs.launchpad.net/bugs/1958224 Title: brltty claiming cp210x devices on 22.04 Status in brltty package in Ubuntu: New Bug description: Distributor ID: Ubuntu Description: Ubuntu Jammy Jellyfish (development branch) Release: 22.04 Codename: jammy brltty: Installed: 6.4-2ubuntu1 brltty appears once again to be claiming cp210x devices with the vendor/product ID of: idVendor=10c4, idProduct=ea60 Example dmesg output: 999.215968] usb 3-6.3: New USB device found, idVendor=10c4, idProduct=ea60, bcdDevice= 1.00 [ 999.215973] usb 3-6.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 999.215975] usb 3-6.3: Product: CP2103 USB to UART Bridge [ 999.215977] usb 3-6.3: Manufacturer: Silicon Labs [ 999.215978] usb 3-6.3: SerialNumber: 0005 [ 999.234070] usbcore: registered new interface driver usbserial_generic [ 999.234081] usbserial: USB Serial support registered for generic [ 999.235262] usbcore: registered new interface driver cp210x [ 999.235272] usbserial: USB Serial support registered for cp210x [ 999.235298] cp210x 3-6.3:1.0: cp210x converter detected [ 999.237039] usb 3-6.3: cp210x converter now attached to ttyUSB0 [ 999.300049] input: PC Speaker as /devices/platform/pcspkr/input/input41 [ 999.807223] input: BRLTTY 6.4 Linux Screen Driver Keyboard as /devices/virtual/input/input42 [ 999.991926] usb 3-6.3: usbfs: interface 0 claimed by cp210x while 'brltty' sets config #1 [ 999.995045] cp210x ttyUSB0: cp210x converter now disconnected from ttyUSB0 [ 999.995066] cp210x 3-6.3:1.0: device disconnected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/1958224/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp

Yes, but it is meant to be so: the Seika Braille device is announced as such, so we have to recognize such devices in brltty, otherwise the Seika Braille devices would not work at all. The question is rather: why is brltty installed on your system?
