usb_id(8)

NAME

usb_id - udev callout to read information from USB devices

SYNOPSIS

usb_id [--usb-info] [--num-info] [--export] [--debug] devpath
usb_id --help

DESCRIPTION

usb_id is normally called from a udev rule, to provide udev with a unique string and additional information (uuid, label) for a USB device. Udev can use this information to create symlinks in /dev to the real device node.

USAGE

usb_id devpath opens the device node specified at the commandline and prints the information chosen by the options.

OPTIONS

The following commandline switches are supported to specify what usb_id should print:

-u, --usb-info

print USB strings instead of, e.g. SCSI strings for a mass storage device

-n, --num-info

print numerical values instead of strings. Implies --usb-info.

-x, --export

print values as environment keys

-h, --help

print usage help
