- RTOS-Agnostic Implementations - Works on bare metal or with FreeRTOS, RT-Thread, or Mynewt without changing the USB code.
- RTOS-Agnostic Interrupt Handlers - Delegates interrupt handling to a central queue and uses semaphores to work without an OS or with FreeRTOS, RT-Thread, or Mynewt.
- Centralized Interrupt Queues - Delegates USB interrupt service routines to a central queue processed by the application thread.
- Compile-Time Buffer Allocations - Pre-allocates all endpoint buffers and control structures at compile time for deterministic memory usage.
- C Object-Oriented Frameworks - Organises USB protocol handling into device and host stacks using C structs with function pointers for polymorphism.
