Comment 5 for bug 1780678

@Erik: I just published an updated version of the chromium snap with the additional raw-usb plug in the candidate/raw-usb channel.

Can you please test and report whether this gives you access to your USB device?

    snap refresh chromium --channel=candidate/raw-usb
    snap connect chromium:raw-usb

If it doesn't, can you please share the output of "journalctl -f | grep DEN" running in another terminal window while observing the problem?
