 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](docs/boards.md) 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:
-
-- Audio Class 2.0 (UAC2)
-- Bluetooth Host Controller Interface (BTH HCI)
-- Communication Class (CDC)
-- Device Firmware Update (DFU): DFU mode (WIP) and 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](https://github.com/WICG/webusb) with vendor-specific class
-
-If you have special need, `usbd_app_driver_get_cb()` can be used to write your own class driver without modifying the stack. Here is how RPi team add their reset interface [raspberrypi/pico-sdk#197](https://github.com/raspberrypi/pico-sdk/pull/197)
-
-## 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**
-- **FreeRTOS**
-- **Mynewt** Due to the newt package build system, Mynewt examples are better to be on its [own repo](https://github.com/hathach/mynewt-tinyusb-example)
