I'm trying to run an app in chromium to talk to an external device connected by serial over USB, as /dev/ttyUSB. And I'm failing.

I'm handicapped by knowing nothing about chromium and not much about ttys and groups in the modern world.

The app says it is trying to contact /dev/ttyUSB0 and then it says it is 'Not Found'.

I'm wondering if there is a permissions, or other security, issue?

Does chromium prevent apps trying to talk to external devices by default? (and if not why not?!)

No, it is not chromium, it is the system administrator, Mr Root. Or in this case, openSUSE install defaults.

That seems to be the case, but the chromium documentation says that an aim of its security architecture is to prevent access to the host filesystem. I'm curious why it isn't doing that, since playing with newgrp was sufficient to achieve access.

I don't see how one thing relates to the other. What it impedes is, I understand, scripts on the web page accessing your filesystem, not that the program accesses the filesystem. - -- Cheers / Saludos, Carlos E. R.
