USB

[JorgenSandberg]

I have installed Ubuntu 18.04.02 LTS.
I want to see the USB devices attached and their drivers. For that I have installed the application usbview. When I run usbview from the command line, I get the error message:

"Can't open the file /sys/kernel/debug/usb/devices.

Verify you have USB compiled into your kernel,
have the USB core modules loaded, and have the
usbdevfs filesystem mounted."

What shall I do to get usbview working in practical terms i.e. text to write on the command line?

Sorry, I found the solution. usbview shall run in administrator mode, sudo usbview. It would have been helpful with that as part of the error message.
