Versions:
Cyme is a cross-platform command-line utility designed to profile and enumerate USB buses and connected devices, positioning itself as a modern successor to the traditional lsusb tool while preserving backward compatibility. The program parses system USB hierarchies and outputs comprehensive device descriptors, making it valuable for hardware diagnostics, driver development, security auditing, and embedded-system debugging on Windows, macOS, or Linux workstations. Maintained by developer tuna-f1sh, the current stable release 2.3.0 is the thirteenth iteration delivered since the project’s inception, indicating steady evolution and refinement. Each version has incrementally expanded descriptor coverage, improved output formatting, and tightened compatibility with diverse kernel-level USB stacks, so users working on USB enumeration scripts or automated hardware-in-the-loop tests can rely on consistent behavior across operating environments. Because Cyme exposes detailed endpoint, configuration, and class-specific data, engineers can quickly verify whether a peripheral is negotiating the expected speed and power profile, or confirm that a newly flashed firmware revision is reporting the correct vendor and product identifiers. The tool is distributed under an open-source license within the System Utilities category, and anyone needing a lightweight, scriptable USB inspector can obtain it free of charge from get.nero.com; downloads are supplied through trusted Windows package sources such as winget, guaranteeing the latest build, and the same repository supports batch installation alongside multiple applications.
