usb-device
==========
Experimental device-side USB stack for embedded devices in Rust.
This crate is still under development and should not be considered production ready or even USB
compliant.
The UsbDevice object represents a composite USB device and is the most important object for
application implementors. The UsbDevice combines a number of UsbClasses (either custom ones, or
pre-existing ones provided by other crates) and a UsbBus device drives to implement the USB device.
The UsbClass trait can be used to implemented USB classes such as a HID device or a serial port. An
implementation may also use a custom class if the required functionality isn't covered by a standard
class.
The UsbBus trait is intended to be implemented by device-specific crates to provide a driver for
each device's USB peripheral.
