Im on ubuntu 20.04 and im facing permissions problem to capture traffic from usb device. Ive made all the things they told me, im on wireshark group and made reconfigure many times to allow non superusers be able to capture traffic.

Any help would be apreciated

Error: The capture session could not be initiated on interface 'usbmon1' (You don't have permission to capture on that device). Please check to make sure you have sufficient permissions.

On Debian and Debian derivatives such as Ubuntu, if you have installed Wireshark from a package, try running

sudo dpkg-reconfigure wireshark-common

selecting "" in response to the question

Should non-superusers be able to capture packets?

adding yourself to the "wireshark" group by running

sudo usermod -a -G wireshark {your username}

and then logging out and logging back in again.
