usb_id − udev callout to read information from USB devices
usb_id
[--usb-info] [--num-info] [--export]
[--debug] devpath
usb_id --help
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.
usb_id devpath opens the device node specified at the commandline and prints the information chosen by the 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
