Known Browser issues

Brave Browser

Unfortunately the Brave developers do not believe that their users can be trusted with Serial/USB devices. This is why - although Chromium based - Brave Browser does not support esc-configurator.com.

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
