I am trying to install wiresahrk on my linux mint 19.2 machine. When executing as root it says:

The capture session could not be initiated on interface 'usbmon1' (Can't open USB bus file /sys/kernel/debug/usb/usbmon/1t: Permission denied).

When executing as normal user, it just says permission denied, because i have no access to debug.

So why is this directory/ not available? I come until usb then the usbmon directory does not exist. i installed it from the apt package.

How can i fix this?

  • Thank you. That worked, can you add as answer so i can mark as solved?

modprobe usbmon as root.

Then if OK add it to /etc/modules.
