Cyme

List system USB buses and devices; a modern lsusb that attempts to maintain compatibility with, but also add new features. Includes a macOS system_profiler SPUSBDataType parser module and libusb tool for non-macOS systems/gathering more verbose information.

The project started as a quick replacement for the barely working lsusb script and is my yearly Rust project to keep up to date! It is currently in flux as I build the foundations, learn about custom serde Deserializers and newer Rust features.

The name comes from the technical term for the type of blossom on a Apple tree: cyme - it is Apple related and also looks like a USB device tree 😃🌸.

Features

• Compatible with lsusb using --lsusb argument. Supports all arguments including --verbose output using libusb.
• Filters like lsusb but that also work when printing --tree. Adds --filter_name, --filter_serial and option to hide empty --hide-buses/--hide-hubs.
• Improved --tree mode.
• Modern terminal features with coloured output, utf-8 characters and icons. Can be turned off and customised.
• Can be used as a library too with system_profiler parsing module, lsusb module using libusb and display module for printing amoungst others.
• --json output that honours filters and --tree.

Planned Features for 1.0.0 Release

• Controllable block data like lsd --blocks
• Modern drawing of device tree with utf-8 boxes.
• Nerd font icon look up and icon theming like lsd --icon.
• libusb optional to get more USB data and support other OS with switch from system_profiler.
• Group by in list mode.
• udev support on Linux to get device driver etc.
• Interface and Device Descriptor icon look up.
• Drawing of headers.
• Tree support of all device interfaces and endpoints.
• --device devpath arg to dump single device.
• Merge of macOS system_profiler output with libusb output to keep special Apple buses.
• Integration tests for lsusb output and new output.
• User defined icon map and colour import.

Install

From crates.io with a Rust tool-chain installed: cargo install cyme. If wishing to do it from within a local clone: cargo install --path ..

If wishing to use only macOS system_profiler and not more verbose information, remove the 'libusb' feature with cargo install --no-default-features cyme

I also have a Homebrew tap: brew tap tuna-f1sh/cyme.

Linux udev

To obtain device and interface drivers being used on Linux like lsusb, one must install 'libudev-dev' via a package manager and the --features udev feature when building. Only supported on Linux targets.

Alias lsusb

If you want to create a macOS version of lsusb, create an alias in your environment with the --lsusb compatibility flag:

alias lsusb='cyme --lsusb'

Examples output:

> lsusb
Bus 000 Device 001: ID 0bda:0411 4-Port USB 3.0 Hub
Bus 002 Device 002: ID 043e:9a60 USB3.1 Hub
Bus 002 Device 007: ID 0781:558c Extreme SSD
Bus 002 Device 008: ID 0bda:8153 Belkin USB-C LAN
Bus 002 Device 005: ID 2109:2817 USB2.0 Hub

Usage

Will cover this more as it develops. Use cyme --help for basic usage.
