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.

TODO

Features planned but not implemented yet:

  • Interface alternate settings
  • Multilingual string descriptors
  • Isochronous endpoints

Features not planning to support at the moment:

  • More than one configuration descriptor (uncommon in practice)
