## 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. It uses udev's hardware database to associate a full  human-readable  name
       to the vendor ID and the product ID.


## 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  de‐
              scriptors  will be shown, when available, for USB device classes including hub, audio,
              HID, communications, and chipcard. Can be used with the **t** option.

### -s
              Show only devices in specified _bus_ and/or _devnum_.  Both IDs are given in  decimal  and
              may be omitted.

### -d
              Show  only  devices  with  the specified vendor and product ID.  Both IDs are given in
              hexadecimal.

### -D
              Do not scan the /dev/bus/usb directory, instead display only information about the de‐
              vice  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 --tree
              Tells  _lsusb_ to dump the physical USB device hierarchy as a tree. Verbosity can be in‐
              creased twice with 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.
