brltty prevents Arduino Leonardo serial port from loading | |||||||||||||||||||
| Reported by s.mis...@bcmi-labs.cc, Jul 4 | Back to list | |||||||||||||||||||
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.115 Safari/537.36 Platform: 9460.60.0 (Official Build) stable-channel panther Steps to reproduce the problem: 1. Plug in Arduino Leonardo board to Chromebook/Chromebox USB port 2. Open shell 3. Run "ls /dev/tty*" What is the expected behavior? A "/dev/ttACM0" device is listed What went wrong? No, "/dev/ttyACM0" device is listed. dmesg reports: [ 2989.362232] usb 1-1: usbfs: interface 0 claimed by cdc_acm while 'brltty' sets config #1 Did this work before? Yes 57 Chrome version: 59.0.3071.91 Channel: stable OS Version: 9460.60.0 Flash Version: I've tracked down the problem to the introduction of the following brltty patch: https://chromium.googlesource.com/chromiumos/overlays/chromiumos-overlay/+/master/app-accessibility/brltty/files/brltty-5.4-canute.patch The "Bristol Canute" is incorrectly using the same USB vendor and product id's as a Arduino Leonardo board. This is preventing Arduino Leonardo users from using their board with Chrome OS as a serial device. I think it would be best to remove the patch linked above for the Bristol Canute as the device is illegally another vendor's USB id.

Looks like that's my fault. The Canute isn't using the Arduino's USB ID, rather I was testing a build of the Canute firmware running on an Arduino and incorrectly used those ids in the experimental driver assuming they were for the Canute. I'll remove those IDs.

Thank you! We've formally announced availability of the Arduino Create Chrome app (https://blog.arduino.cc/2017/07/17/arduino-create-comes-to-chrome-os-devices/) and mentioned Leonardo board support will be restored in a later Chrome OS release.

I've been talking to the guys from Arduino and glad to have cleared up the confusion. Canute is an unreleased product not illegally using the Arduino ID. I hope this is able to be quickly resolved within Chromium so the Arduino Create app can have Leonardo support reinstated. Cheers, Ed (Bristol Braille Tech.)

The following revision refers to this bug: https://chromium.googlesource.com/chromiumos/overlays/chromiumos-overlay/+/0ce5efe415dc2ac320cb0cf9ad957715ed32968a commit 0ce5efe415dc2ac320cb0cf9ad957715ed32968a Author: Dominic Mazzoni <dmazzoni@chromium.org> Date: Sat Sep 09 00:36:10 2017 Remove Canute braille display support. The Canute driver was experimental only, so this won't affect users. The driver was incorrectly identifying Arduino Leonardo as Canute, which *was* affecting users. We need to fix that before re-landing.

Requesting merge to 62 because this is affecting Arduino Leonardo users.
