## What it is
Cyme is a modern cross-platform command-line tool for listing system USB buses and devices, compatible with lsusb while adding richer tree views, filtering, and colored terminal output. It profiles full device descriptors using a pure Rust profiler built on nusb, with libusb and macOS system_profiler backends also available.

## Use cases
- list usb devices connected to my system
- modern lsusb replacement for macos
- show usb device tree with descriptors
- debug usb devices during embedded development
- filter usb devices by name or serial number
- dump verbose usb device descriptors like lsusb -v

## When to choose
- you need lsusb-compatible output on macOS, Windows, or Linux
- you want a readable colored tree view of USB buses, devices, interfaces, and endpoints
- you need filtering options like name, serial, or class when inspecting USB devices

## When to avoid
- you need to write to or control USB devices rather than just list them
- you require byte-identical lsusb verbose output for automated parsing
- you need a GUI-based USB inspection tool
