This library provides a reliable, packet-based transport over a physical USB connection with an asynchronous API.

Features
--------

This crate provides the following main features:

* `host` enables the host-side part,
* `device` enables the device-side part.

To be useful, at least one of these features must be enabled.

Additionally, the feature `trace-packets` can be enabled to log USB packets at log level trace.

Requirements
------------

The minimum support Rust version (MSRV) is 1.73.

The host-side part supports any operating system supported by `libusb`.

The device-side part requires Linux and a USB device controller (UDC).
