lsusb - list USB devices
lsusb [
options ]
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.
-
-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,
communications, and chipcard. Can be used with the t option.
-
-s [[bus]:][devnum]
- Show only devices in specified bus and/or
devnum. Both IDs are given in decimal and may be omitted.
-
-d [vendor]:[product]
- Show only devices with the specified vendor and product ID.
Both IDs 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, --tree
- Tells lsusb to dump the physical USB device
hierarchy as a tree. Verbosity can be increased twice with the v
option.
-
-V, --version
- Print version information on standard output, then exit
successfully.
If the specified device is not found, a non-zero exit code is returned.
