NAME

6       hid-recorder - HID Input device recorder.

SYNOPSIS

9       hid-recorder
10
11       hid-recorder [OPTIONS] [/dev/hidrawX] [[/dev/hidrawY] ... ]
12

OPTIONS

14       -d, --debugfs
15           use HID debugfs node. Some devices (like "Logitech USB Receiver" or
16           "Apple Magic Mouse") grabs the hidraw output leading to an empty
17           output. Fortunately, relying on HID debugfs can help us most of the
18           time. However, if hte device does report two many events at once
19           (multitouch panles for example), the HID debugfs node is missing a
20           lot of events, preventing us to make this the default behaviour.

DESCRIPTION

23       hid-recorder is a tool that allow users to capture hidraw description
24       and events in order to replay them through the uhid kernel module.
25
26       The first invocation type displayed above (without arguments) causes
27       hid-recorder to let the user choose which hidraw she will use,
28       including the name the device.
29
30       Several hidraw nodes can be given to hid-recorder. In this case, the
31       recording of each node are multiplexed thanks to the tag D: as seen
32       below.
33
34       hid-recorder needs to be able to read from the hidraw device; in most
35       cases this means it must be run as root.
36
37       hid-recorder and hid-replay are used to debug kernel issues with HID
38       input devices. The output of hid-recorder has the following syntax:
39
40       ·   # lines comments
41
42       ·   D: tell which device we are currently working with
43
44       ·   R: size dump_of_report_descriptor_in_hexadecimal
45
46       ·   N: common_name_of_the_device
47
48       ·   P: physical_path
49
50       ·   I: bus vendor_id product_id
51
52       ·   E: timestamp size report_in_hexadecimal
53

EXIT CODE

55       hid-recorder returns EXIT_FAILURE on error.
