HID replay is a utility to create virtual HID devices via the uhid kernel module. Typically the input is a recording created by hid-recorder.

This is a Rust reimplementation of hid-replay from hid-tools.

hid-replay needs access to the /dev/uhid device and typically needs to run as root.

A pre-built binary is available for our releases. Simply download the hid-replay.zip, unpack it and you are good to go:

$ unzip hid-replay.zip
$ chmod +x hid-replay
$ sudo ./hid-replay

Installation with cargo

The easiest is to install with cargo as root:

$ sudo cargo install hid-replay
$ sudo hid-replay path/to/recording

Alternatively leave out the sudo which installs installs in $CARGO_HOME (usually $HOME/.cargo) and run with pkexec instead.

$ cargo install hid-replay
$ pkexec hid-replay path/to/recording

pkexec will ask for your user's password.

Alternatively you can install hid-replay so you can access it via sudo:

Sudo-compatible Installation

This is the default cargo installation but requires that you add the path manually when running hid-replay:

$ cargo install hid-replay
$ sudo $HOME/.cargo/bin/hid-replay path/to/recording

Install hid-replay in /usr/local/ which is typically part of the default $PATH.

$ sudo CARGO_INSTALL_ROOT=/usr/local cargo install hid-replay
$ sudo hid-replay path/to/recording

This is the least safe option as once read access is granted, any process can create virtual HID devices. This allows for malicious interference with your running session.

$ cargo install hid-replay
$ sudo chmod o+r /dev/uhid
$ hid-replay path/to/recording

It is recommended to remove these permissions once need for replaying is over:

$ sudo chmod o-r /dev/uhid
