🦀 udever

Stop writing udev rules by hand.

udever is a blazing fast, interactive CLI tool to manage udev rules for your USB devices. Generate permission rules, create symlinks, and reload drivers without leaving your terminal.

---

⚡ Features

• Interactive Selection: Fuzzy-search your connected USB devices. No more lsusb grep hunting.
• Smart OS Detection: Automatically selects the correct group (uucp for Arch/Manjaro, dialout for Debian/Ubuntu).
• Safe & Robust:
  • Filters out Root Hubs to prevent system accidents.
  • Performs systemd-udevd health checks before running.
  • Validates syntax before writing.
• Instant Feedback: Automatically reloads rules and triggers device events (udevadm trigger).
• Editor Integration: Open generated rules in nano, vim, or nvim for manual tweaking.
• Symlink Generator: Easily create persistent device names (e.g., /dev/my_arduino).

🚀 Installation

From Crates.io (Recommended)

You need Rust installed.

cargo install udever

Since udever requires root privileges to manage udev rules, i recommend making it available to sudo:

# Ensure that cargo's path is valid
# in ~/.bashrc etc.
export PATH="$HOME/.cargo/bin:$PATH"
# You should link
sudo ln -s $HOME/.cargo/bin/udever /usr/local/bin/udever

Arch Linux (AUR)

You can install udever from the AUR using an AUR helper like yay or paru.

yay -S udever
# or
paru -S udever

From Source

git clone [https://github.com/lazytatzv/udever.git](https://github.com/lazytatzv/udever.git)
cd udever
cargo install --path .

📖 Usage

Note: Root privileges are required to write into /etc/udev/rules.d/.

Run the interactive wizard:

sudo udever

Quick Commands

Create a rule for a specific device ID (VID:PID):

sudo udever --id 1234:5678

Generate shell completions (bash/zsh/fish):

udever --completion zsh > _udever

🛠 Troubleshooting

"udev daemon is NOT active" udever relies on systemd-udevd. If the tool warns you, try starting the service:

sudo systemctl start systemd-udevd
