usb_gadget 0.6.0

Expose standard or fully custom USB peripherals (gadgets) through a USB device controller (UDC) on Linux.

0.6.0

• FIX: Refresh OUT endpoints on enable to recover from host de-configuration, replacing dead AioStream instances without requiring consumers to re-subscribe.
• REFACTOR: Restructure endpoint directory layout — move functionfs/endpoint.dart to endpoint/core.dart and relocate descriptors/events under functions/ffs/.
• REFACTOR: Simplify Aio initialization in EndpointInFile and EndpointOutFile by passing file descriptors directly to Aio.fromEndpointConfig.
• REFACTOR: Refactor EndpointOutFile to use a StreamController proxy for a stable broadcast stream across USB enable/disable cycles.
• REFACTOR: Restructure kernel AIO bindings — rename platform/aio to platform/libaio, introduce a Libaio wrapper with scratch arrays to minimize allocations, and add an Iocb owning wrapper with factory methods for read/write ops.
• REFACTOR: Relocate AioStream and BufferPool to lib/src/endpoint/aio/; remove seek offsets and ensure data is copied from native buffers before pool return to prevent use-after-free.
• REFACTOR: Remove AioSink, old AioContext, and other high-level AIO abstractions in favor of the more direct libaio interface.
• FEAT: Add FFI bindings and Epoll wrapper for Linux epoll and eventfd system calls, supporting I/O multiplexing with create, add, modify, delete, and wait, plus eventfd notification helpers.
• REFACTOR: Use DynamicLibrary.process() to access libc in errno handling.

0.5.0

• FIX: Various endpoint lifecycle and resource management fixes across FunctionFs and HIDFunctionFs.
• FIX: Several reliability improvements to AioSink around write queue and resource release.
• REFACTOR: Consolidate endpoint and resource lifecycle management into base classes.

0.4.3

• FIX: Add missing fatal method to Logger class
• CHORE: Update logger exports to include the Logger class
• CHORE: Remove the PlatformLogger export

0.4.2

• CHORE: Export ILogger as public to allow custom mixin creation outside the library.
• FIX: Release endpoints on disable to prevent resource leaks.

0.4.1

• FEAT: Add compile-time environment-based logging configuration.
• REFACTOR: Simplify log level representation.
• REFACTOR: Enhance log formatting and color handling.
• FIX: Replace hardcoded log level with environment-based constant.

0.4.0

• FEAT: Initial release of the package.
