 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:
+Supports multiple device configurations by dynamically changing USB descriptors, low power functions such like suspend, resume, and remote wakeup. The 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
+-  Communication Device Class (CDC)
+-  Device Firmware Update (DFU): DFU mode (WIP) and Runtime
 -  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)
+-  Network with RNDIS, Ethernet Control Model (ECM), Network Control Model (NCM)
+-  Test and Measurement Class (USBTMC)
+-  Video class 1.5 (UVC): work in progress
 -  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
 ==========

 - Human Interface Device (HID): Keyboard, Mouse, Generic
 - Mass Storage Class (MSC)
- Hub currently only supports 1 level of hub (due to my laziness)
+- Communication Device Class: CDC-ACM
+- Vendor serial over USB: FTDI, CP210x
+- Hub with multiple-level support
+
+Similar to the Device Stack, if you have a special requirement, `usbh_app_driver_get_cb()` can be used to write your own class driver without modifying the stack.
+
+TypeC PD Stack
+==============
+
+- Power Delivery 3.0 (PD3.0) with USB Type-C support (WIP)
+- Super early stage, only for testing purpose
+- Only support STM32 G4

 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.
