Returns the RT driver to the function state of previous iteration, which did not support the will_detach. Behavior should be fine without this feature. This removes much of the added bloat to track state, and handle requests in the APP_DETACH state which is no longer required. Removes the optional bloat added to the RT driver, such as responding to GETSTATE requests. Fixes the DFU Mode to extract the attr bits from the functional descriptor when opened. Fixes some incorrect bitwise if checks. Also, updates some naming of functions to be consistent with the rest of the library.
TinyUSB
TinyUSB is an open-source cross-platform USB Host/Device stack for embedded system, designed to be memory-safe with no dynamic allocation and thread-safe with all interrupt events are deferred then handled in the non-ISR task function.

Here is the list of supported Boards that can be used with provided examples.
Device Stack
Supports multiple device configurations by dynamically changing usb descriptors. Low power functions such like suspend, resume, and remote wakeup. Following device classes are supported:
- USB Audio Class 2.0 (UAC2) still work in progress
- Bluetooth Host Controller Interface (BTH HCI)
- Communication Class (CDC)
- Device Firmware Update (DFU): only Runtinme
- Human Interface Device (HID): Generic (In & Out), Keyboard, Mouse, Gamepad etc ...
- Mass Storage Class (MSC): with multiple LUNs
- Musical Instrument Digital Interface (MIDI)
- Network with RNDIS, CDC-ECM (work in progress)
- USB Test and Measurement Class (USBTMC)
- Vendor-specific class support with generic In & Out endpoints. Can be used with MS OS 2.0 compatible descriptor to load winUSB driver without INF file.
- WebUSB with vendor-specific class
Host Stack
Most active development is on the Device stack. The Host stack is under rework and largely untested.
- Human Interface Device (HID): Keyboard, Mouse, Generic
- Mass Storage Class (MSC)
- Hub currently only supports 1 level of hub (due to my laziness)
OS Abstraction layer
TinyUSB is completely thread-safe by pushing all ISR events into a central queue, then process it later in the non-ISR context task function. It also uses semaphore/mutex to access shared resources such as CDC FIFO. Therefore the stack needs to use some of OS's basic APIs. Following OSes are already supported out of the box.
- No OS : Disabling USB IRQ is used as way to provide mutex
- FreeRTOS
- Mynewt Due to the newt package build system, Mynewt examples are better to be on its own repo
Getting Started
Here are the details for getting started with the stack.
