SYNOPSIS

hid-recorder [--output=output_file] [/dev/hidrawX] [[/dev/hidrawX] [...]]

OPTIONS

--output=path/to/file: Write the output to the given file. When omitted, hid-recorder prints to stdout.

DESCRIPTION

When invoked without arguments, hid-recorder shows a list of available devices.

hid-recorder needs to be able to read from the hidraw device; usually this means it must be run as root.

•: R: The report descriptor length in bytes, followed by the report descriptor bytes in hexadecimal
•: N: the name of the device
•: P: physical path
•: I: bus vendor_id product_id
•: E: timestamp size report in hexadecimal

EXIT CODE

hid-recorder returns 1 on error.
