tinyusb is designed to be OS-ware and run across RTOS vendors, thanks to its OS Abstraction Layer (OSAL). However, it can also run without an RTOS (OSAL will be expanded to be a state machine in this case). Currently the following OS can be run with tinyusb (out of the box). tinyusb is designed to be OS-ware and run across RTOS vendors, thanks to its OS Abstraction Layer (OSAL).

- LPC11uxx & LPC13uxx cannot able to STALL Control OUT endpoint !!! --> unsupported with data out request may cause host stuck with control transfer forever.

## How Can I Help ## How Can I Help ##
If you find my little USB stack is useful, please take some time to file any issues that you encountered. It is not necessary to be a software bug, it can be a question, request, suggestion etc. We can consider each github's issue as a forum's topic. Alternatively, you can buy me a cup of coffee if you happen to be in Hochiminh city. If you find my little USB stack is useful, please take some time to file any issues that you encountered.
