nusb

nusb

A new pure-Rust library for cross-platform low-level access to USB devices.

Documentation

Compared to rusb and libusb

• Pure Rust, no dependency on libusb or any other C library.
• Async-first, while not requiring an async runtime like tokio or async-std. Still easily supports blocking with futures_lite::block_on.
• 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.

Current status

• Support for Linux, Windows, macOS, and Android
• Device listing and descriptor parsing
• Transfers on control, bulk and interrupt endpoints
• Device connect / disconnect events on all platforms
• Used by probe-rs, packetry, postcard-rpc and others, but still relatively new. Please test with your device and report issues.
