SecurityError is not caught and displayed #20
Description
Issue encountered on Ubuntu 24.04 LTS, using chromium installed as a snap package.
Page loads fine, RTLSDR appears in USB device list, however when you go to start, nothing happens.
Inspection of the console showed the error: SecurityError: Failed to execute 'open' on 'USBDevice': Access denied
Things I checked:
- kernel modules issues - all dvb related kernel modules were blacklisted
- udev permissions - udev rules for RTLSDR were present, allowing access to users in plugdev group (which the current user was a part of)
A quick google suggested this is something to do with snap packages and their security settings. I was under time pressure to make this work, so I ended up bypassing the problem by installing google chrome from a deb package, which worked fine.
The SecurityError really should be caught, with an error message displayed. Unsure if there's a known solution for accessing USB devices from within snap packages.
