# 0.14.0
*August 23, 2022*
- Improve compiler support for CCRX and IAR
- Add timeout to `osal_queue_receive()`
- Add `tud_task_ext(timeout, in_isr)` as generic version of `tud_task()`. Same as `tuh_task_ext()`, `tuh_task()`
- Enable more warnings `-Wnull-dereference -Wuninitialized -Wunused -Wredundant-decls -Wconversion`
## Add new examples
- `host/bare_api` to demonstrate generic (app-level) enumeration and endpoint transfer
- `dual/host_hid_to_device_cdc` to run both device and host stack concurrently, get HID report from host and print out to device CDC. This example only work with multiple-controller MCUs and rp2040 with the help of pio-usb as added controller.
## Controller Driver (DCD & HCD)
- Enhance rhports management to better support dual roles
- `CFG_TUD_ENABLED`/`CFG_TUH_ENABLED`, `CFG_TUD_MAX_SPEED`/`CFG_TUH_MAX_SPEED` can be used to replace `CFG_TUSB_RHPORT0_MODE`/`CFG_TUSB_RHPORT1_MODE`
- `tud_init(rhport)`, `tuh_init(rhport)` can be used to init stack on specified roothub port (controller) instead of `tusb_init(void)`
- Add dcd/hcd port specific defines `TUP_` (stand for tinyusb port-specific)
### dwc2
- Update to support stm32 h72x, h73x with only 1 otg controller
- Fix overwrite with grstctl when disable endpoint
### EHCI
- Fix an issue with EHCI driver
### msp430
- Fix for possible bug in msp430-elf-gcc 9.3.0
### nrf5x
- Fix DMA access race condition using atomic function
### pic32
- Fix PIC32 sanity
### rp2040
- Add PICO-PIO-USB as controller (device/host) support for rp2040
- Use shared IRQ handlers, so user can also hook the USB IRQ
- Fix resumed signal not reported to device stack
### stm32fsdev
- Add support for stm32wb55
## Device Stack
- [Audio] Add support for feedback endpoint computation
- New API `tud_audio_feedback_params_cb()`, `tud_audio_feedback_interval_isr()`.
- Supported computation method are: frequency with fixed/float or power of 2. Feedback with fifo count is not yet supported.
- Fix nitfs (should be 3) in `TUD_AUDIO_HEADSET_STEREO_DESCRIPTOR`
- Fix typo in `audiod_rx_done_cb()`
- [DFU] Fix coexistence with other interfaces BTH, RNDIS
- [MSC] Fix inquiry response additional length field
- [Vendor] Improve write performance
## Host Stack
- Add new API `tuh_configure(rhport, cfg_id, cfg_param)` for dynamic port specific behavior configuration
- [HID] Open OUT endpoint if available
- [Hub] hub clear port and device interrupts
### [USBH] Major improvement
- Rework usbh control transfer with complete callback. New API `tuh_control_xfer()` though still only carry 1 usbh (no queueing) at a time.
- Add generic endpoint transfer with `tuh_edpt_open()`, `tuh_edpt_xfer()`. Require `CFG_TUH_API_EDPT_XFER=1`
- Support app-level enumeration with new APIs
- `tuh_descriptor_get()`, `tuh_descriptor_get_device()`, `tuh_descriptor_get_configuration()`, `tuh_descriptor_get_hid_report()`
- `tuh_descriptor_get_string()`, `tuh_descriptor_get_manufacturer_string()`, `tuh_descriptor_get_product_string()`, `tuh_descriptor_get_serial_string()`
- Also add `_sync()` as sync/blocking version for above APIs
