Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

Added

  • DummyUsbBus without functionality to allow examples that actually compile (but not run).
  • Extended UsbRev enum with variants for USB 1.0 and 1.1.

Changed

  • [breaking] The control pipe is now provided in the UsbDeviceBuilder API to allow for user-provided control pipes. This makes it so that control pipes have configurable sizing.
  • Don't require UsbBus to be Sync. If a UsbBus is not Sync, it can still be used to make a UsbDevice, but that UsbDevice will not be Sync (ensuring soundness).

0.3.2 - 2024-03-06

Added

  • A new log feature can be enabled to provide logging and tracing information about the USB interface.

Changed

  • [breaking] LangIDs no longer implement TryFromPrimitive. The minor version has not been bumped as this was not intended to be used in the public API.
    • If this is problematic, please open an issue in the main usb-device repository.
  • Changed handling of EP0 state to eliminate unexpected issues with device enumeration

0.3.1 - 2023-11-15

Added

  • BuilderError, LangID, StringDescriptors now in prelude
  • LangID now in class_prelude

Changed

  • Updated documentation, including example code

0.3.0 - 2023-11-13

Fixed

  • Fixed a defect where enumeration may fail due to timing-related issues (#128)

Added

  • New enums and allocators for Isochronous endpoints (#60).
  • Ability to select USB revision (#116).
  • Added support for alternate settings on interfaces (#114).
  • Added support for architectures without atomics (#115).
  • Added support for multi-language STRING desc (#122).
    • UsbDeviceBuilder has a public .extra_lang_ids() method to specify LANGIDs besides ENGLISH_US(0x0409)

Breaking

  • Acess numeric form of EndpointType variants now require a .to_bm_attributes(). (#60)
  • DescriptorWriter::iad() now requires a Option<StringIndex> to optionally specify a string for describing the function (#121)
  • .manufacturer(), .product() and .serial_number() of UsbDeviceBuilder are now replaced with the strings() function that accepts a StringDescriptor list to allow multilanguage support (#122)
  • Various methods of the UsbDeviceBuilder now return Result<> types instead of internally panicking.

Changed

  • EndpointType enum now has fields for isochronous synchronization and usage (#60).
  • descriptor_type::STRING of fn get_descriptor() will send the LANGIDs supported by device, and respond STRING Request with specified LANGID. (#122)
  • UsbError is now copyable and comparable (#127)

0.2.9 - 2022-08-02

Added

  • Optional support for defmt (#76).

Fixed

  • Fixed an issue where USB devices were not enumerating on Windows (#32)
