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,
communications, 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).
