We should review how the package works but meanwhile the udev rules change is going to resolve the conflict
** Description changed: + * 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. Those devices are uncommon and + it's arguably an hardware bugs they are using those IDs. + + ------------------- + 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 + 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 + 999.215968] 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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958224 Title: brltty claiming cp210x devices on 22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/brltty/+bug/1958224/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
