NAME
usb-devices - print USB device details SYNOPSIS
usb-devices DESCRIPTION
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/ker- nel/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.

NAME
lsusb - list USB devices SYNOPSIS
lsusb [ options ] DESCRIPTION
lsusb is a utility for displaying information about USB buses in the system and the devices connected to them. OPTIONS
-v, --verbose Tells lsusb to be verbose and display detailed information about the devices shown. This includes configuration descriptors for the device's current speed. Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communi- cations, and chipcard. -s [[bus]:][devnum] Show only devices in specified bus and/or devnum. Both ID's are given in decimal and may be omitted. -d [vendor]:[product] Show only devices with the specified vendor and product ID. Both ID's are given in hexadecimal. -D device Do not scan the /dev/bus/usb directory, instead display only information about the device whose device file is given. The device file should be something like /dev/bus/usb/001/001. This option displays detailed information like the v option; you must be root to do this. -t Tells lsusb to dump the physical USB device hierarchy as a tree. This overrides the v option. -V, --version Print version information on standard output, then exit successfully. RETURN VALUE
If the specified device is not found, a non-zero exit code is returned. FILES
/var/lib/usbutils/usb.ids A list of all known USB ID's (vendors, products, classes, subclasses and protocols). SEE ALSO
