lsusb(8) Linux USB Utilities lsusb(8) 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 de- vice's current speed. Class descriptors will be shown, when avail- able, for USB device classes including hub, audio, HID, communica- tions, 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 infor- mation 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 success- fully. RETURN VALUE If the specified device is not found, a non-zero exit code is returned. FILES /usr/local/share/usbids/usb.ids A list of all known USB ID's (vendors, products, classes, subclasses and protocols). SEE ALSO lspci(8), usbview(8).
