Known Browser issues

Brave Browser

Prior to 1.58 (Sept 2023) it was not possible to enable Web Serial (via a brave://flags setting). As of 1.69 (Sept 2024), it is now enabled by default, and works with esc-configurator.com with no configuration changes required.

Browsers via Snap

When using Browsers installed via snap, it might happen that no serial devices are shown in the Serial port selection Box. In this case you might want to try the following:

- close chromium
- edit (with sudo) /var/lib/snapd/apparmor/profiles/snap.chromium.chromium, add the following line to the profile:

    @{PROC}/tty/drivers r,

- reload the apparmor profile with: "sudo apparmor_parser -r /var/lib/snapd/apparmor/profiles/snap.chromium.chromium"
- run "journalctl -f | grep chromium" in a terminal, start chromium, and try to access your device
- share the updated journalctl output
