@ -9,3 +9,9 @@ For this program to be useful, you will need to mount the debug filesystem
debugfs /sys/kernel/debug debugfs noauto 0 0

The debugfs root directory is accessible only to the root user by default.
You can grant access to the USB device info (as well as the rest of the
debugfs tree) with the "uid", "gid", and "mode" mount options. For example:
debugfs /sys/kernel/debug debugfs noauto,mode=755 0 0
