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 informa‐ tion. ### /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)](https://www.chedong.com/phpMan.php/man/lsusb/8/markdown), [**usbview**(8)](https://www.chedong.com/phpMan.php/man/usbview/8/markdown). ## AUTHORS Greg Kroah-Hartman <> Randy Dunlap <> Frans Pop <> usbutils-014 23 June 2009 [usb-devices(1)](https://www.chedong.com/phpMan.php/man/usb-devices/1/markdown)
