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)
- Communication Device 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

- 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)

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.
