Without an RTOS it simply handles concurrency issues between the main code and interrupts. The code is almost entirely agnostic of MCU and lives in ``src/osal``.
+The OS Abstraction Layer is responsible for providing basic data structures for TinyUSB that may allow for concurrency when used with an RTOS. Without an RTOS it simply handles concurrency issues between the main code and interrupts.
 
-In RTOS configurations, tud_task()/tuh_task() blocks behind a synchronization structure when the event queue is empty, so that the scheduler may give the CPU to a different task. To take advantage of the library's capability to yield the CPU when there are no actionable USB device events, ensure that the `CFG_TUSB_OS` symbol is defined, e.g `OPT_OS_FREERTOS` enables the FreeRTOS scheduler to schedule other threads than that which calls `tud_task()/tuh_task()`.

-#### Composite CDC + UAC2 on Pico
-
-This example provides a composite CDC + UAC2 device on top of a Raspberry Pi
-Pico board.
-
-
-#### Use Cases
-
-- The CDC + UAC2 composite device happens to be important, especially in the
-  amateur radio community.
-
-  Modern radios (`rigs`) like Icom IC-7300 + IC-705 expose a sound card and a
-  serial device (`composite device`) to the computer over a single USB cable.
-  This allows for Audio I/O and CAT control over a single USB cable which is
-  very convenient.
-
-  By including and maintaining this example in TinyUSB repository, we enable
-  the amateur radio community to build (`homebrew`) radios with similar
-  functionality as the (expensive) commercial rigs.
-
-  This PR is important in bridging this specific gap between the commercial
-  rigs and homebrew equipment.
-
-- https://digirig.net/digirig-mobile-rev-1-9/ is a digital interface for
-  interfacing radios (that lack an inbuilt digital interface) with computers.
-  Digirig Mobile works brilliantly (is OSS!) and is a big improvement over
-  traditional digital interfaces (like the SignaLink USB Interface). By using a
-  Raspberry Pi Pico powered CDC + UAC2 composite device, we can simplify the
-  Digirig Mobile schematic, drastically reduce the manufacturing cost, and
-  (again) enable the homebrewers community to homebrew a modern digital interface
-  with ease themselves.

-
-#### Build Steps
-
-```
-cd examples/device/cdc_uac2
-
-export PICO_SDK_PATH=$HOME/pico-sdk
-
-cmake -DFAMILY=rp2040 pico .
-
-cmake -DFAMILY=rp2040 -DCMAKE_BUILD_TYPE=Debug # use this for debugging
-
-make BOARD=raspberry_pi_pico all
-```

-#### Development Notes
-
-Please try to keep this code synchronized with the `uac2_headset` example
-included in this repository.
