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. ## RETURN VALUE If sysfs is not mounted, a non-zero exit code is returned. ## FILES - **/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. ## SEE ALSO [**lsusb**(8)](/lsusb/8.md), [**usbview**(8)](/usbview/8.md). ## AUTHORS Greg Kroah-Hartman \ Randy Dunlap \ Frans Pop \
