usb-devices is a (bash) shell script that can be used to display details of USB
buses in the system and the devices connected to them.
The output of the script is similar to the usb/devices file
available either under /proc/bus (if usbfs is mounted), or under
/sys/kernel/debug (if debugfs is mounted there). The script is
primairily intended to be used if the file is not available.
In contrast to the usb/devices file, this script only lists
active interfaces (those marked with a "*" in the usb/devices
file) and their endpoints.
Be advised that there can be differences in the way information is sorted,
as well as in the format of the output.
