stm32 fsdev

  • Add STM32L5 support
  • Implement dcd_edpt_iso_alloc() and dcd_edpt_iso_activate()

OHCI

  • Allows configurable root hub ports, handles SMM mode (Ref OHCI spec 5.1.1.3.3) and Bios mode (Ref OHCI spec 5.1.1.3.4)
  • Fix FrameIntervalToggle must be toggled after we write the FrameInterval (Ref OHCI Spec 7.3.1)
  • Wait PowerOnToPowerGoodTime after we enable power of the RH ports (Ref OHCI Spec 7.4.1)
  • Generate port interrupts for devices already connected during init.
  • Fix issue when removing queue head
  • Disable MIE during IRQ processing and clear HccaDoneHead on completion as per OCHI Spec Page 80

Device Stack

  • Add optional hooks tud_event_hook_cb()

Audio (UAC2)

  • Fix feedback EP buffer alignment.
  • Fix encoding, update example
  • Improve IN transfer

Bluetooth

  • Add historical EP compatibility for Bluetooth HCI

CDC

  • Fix line_coding alignment
  • Fix typo in cdc line coding enum

MIDI

  • Fix stream_write() always writes system messages to cable 0
  • Fix incorrect NOTE_ON, NOTE_OFF definitions

USBTMC

  • Fix tmc488 bit order

Vendor

  • fix read()/write() race condition

Video (UVC)

  • Add the capability for video class to handle a bulk endpoint in the streaming interface.

Host Stack

USBH

  • Add new APIs: tuh_interface_set(), tuh_task_event_ready(), tuh_edpt_abort_xfer(), tuh_rhport_reset_bus(), tuh_rhport_is_active()
  • Fix issue when device generate multiple attach/detach/attach when plugging in
  • Prefer application callback over built-in driver on transfer complete event
  • Correct hcd_edpt_clear_stall() API signature
  • Separate bus reset delay and contact debouncing delay in enumeration
  • Support usbh_app_driver_get_cb() for application drivers
  • Fix usbh enumeration removal race condition
  • Add optional hooks tuh_event_hook_cb()

CDC

  • Breaking: change tuh_cdc_itf_get_info() to use tuh_itf_info_t instead of tuh_cdc_info_t
  • Fix cdc host enumeration issue when device does not support line request
  • Add support for vendor usb2uart serial: ftdi, cp210x, ch9102f
  • Improve sync control API e.g tuh_cdc_set_control_line_state(), tuh_cdc_set_line_coding()
