hid-recorder
HID Recorder is a utility to record HID data from a /dev/hidraw
device and print both
the HID Report Descriptor and the HID Reports in a human and machine-readable format.
This output can be used for analysis and/or replaying devices and their events.
This is a Rust reimplementation of hid-recorder from hid-tools
Installation
The easiest is to install with cargo:
$ cargo install hid-recorder
$ hid-recorder
This installs in $CARGO_HOME
(usually $HOME/.cargo
) and is sufficient for
use-cases where you only neeed to analyze the HID Report Descriptor (not
events from the device)
For use-cases where you need to record events (HID Reports) hid-recorder
needs read access to the respective /dev/hidraw
device. Typically this
means you need to run as root. The easiest way is to run through pkexec
which will ask for your user's password:
$ pkexec hid-recorder
Alternatively you can install hid-recorder so you can access it via sudo:
Sudo-compatible Installation
Install as user in $CARGO_HOME
This is the default cargo
installation but requires that you add the
path manually when running hid-recorder:
$ cargo install hid-recorder
$ sudo $HOME/.cargo/bin/hid-recorder
Install as root in /usr/local
Install hid-recorder in /usr/local/
which is typically part of the
default $PATH
.
$ sudo CARGO_INSTALL_ROOT=/usr/local cargo install hid-recorder
$ sudo hid-recorder
Allow access to the device to non-root users
This is the least safe option as once read access is granted, any process can read events from the device. If the device is a keyboard this allows for key loggers to read all events.
$ cargo install hid-recorder
$ sudo chmod o+r /dev/hidraw0
$ hid-recorder
It is recommended to remove these permissions once the recording is complete:
$ sudo chmod o-r /dev/hidraw0
Recording a device
The typical use is a request for "attach a hid recording" in an issue. To do this, run hid-recorder with no arguments and pick the device in question, e.g.
$ sudo hid-recorder
