nusb supports Windows, macOS, and Linux, and provides both async and blocking APIs for listing and watching USB devices, reading descriptor details, opening and managing devices and interfaces, and performing transfers on control, bulk, and interrupt endpoints.

Compared to rusb and libusb

• Pure Rust, no dependency on libusb or any other C library.
• Async-first, while not requiring an async runtime.
• No context object. You just open a device. There is a global event loop thread that is started when opening the first device.
• Thinner layer over OS APIs, with less internal state.
