usb-devices - print USB device details
usb-devices
usb-devices is a 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
primarily 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.
If sysfs is not mounted, a non-zero exit code is returned.
/sys/bus/usb/devices/usb*
The part of the sysfs tree the script walks through to
assemble the printed information.
/proc/bus/usb/devices
Location where the usb/devices file can normally be found
for Linux kernels before 2.6.31, if usbfs is mounted.
/sys/kernel/debug/usb/devices
Location where the usb/devices file can normally be found
for Linux kernel 2.6.31 and later, if debugfs is mounted.
