Kevin Mehall 6895347f4b Define a new Error type instead of re-exporting std::io::Error 
The default mapping from OS error codes to io::Error's messages is often wrong
or misleading. We can do a lot better, but it takes a lot of error-handling code.

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, and macOS
  • Device listing and descriptor parsing
  • Transfers on control, bulk and interrupt endpoints
  • Used in production by probe-rs and others, but still relatively new. Please test with your device and report issues.
