usbview

[Patrick Dupre]

Hello,

I got the following message:

Can not open the file /sys/kernel/debug/usb/devices

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

I assume that I need to install a module

Thank.

The problem arises only if you are running usbview as normal user!
"sudo usbview" does what you expect!

Kind regards

Why does usbview require root, when "lsusb -v" seems to provide the same type of 
detail to a normal user?
