General
Controller Driver (DCD & HCD)
-
DWC2
- Fix incorrect handling of Zero-Length Packets (ZLP) in the DWC2 driver when receiving data (OUT transfers)
Improve EP0 multi-packet logicSupport EP0 with max packet size = 8For IN endpoint, write initial packet directly to FIFO and only use TXFE interrupt for subsequent packetsFix ISO with bInterval > 2 using incomplete IN interrupt handling.Fix compile issues when enabling both host and deviceClear pending suspend interrupt after USB reset (enum end)Improve host closing endpoint and channel handling when device is unplugged
FSDEV (STM32)
- Fix AT32 USB interrupt remapping in
dcd_int_enable()
OHCI
- Add initial LPC55 OHCI support
- Improve data cache support
Device Stack
-
USBD Core
- Support configurable EP0 buffer size CFG_TUD_ENDPOINT0_BUFSIZE
- Make dcd_edpt_iso_alloc/activate as default API for ISO endpoint
-
Audio
- Add UAC1 support
- Implement RX FIFO threshold adjustment with
tud_audio_get/set_ep_in_fifo_threshold()
-
CDC
- Migrate to endpoint stream API
-
HID
- Fix HID stylus descriptor
-
MIDI
- Migrate to endpoint stream API
- Add
tud_midi_n_packet_write_n() and tud_midi_n_packet_read_n()
-
MTP
- Fix incorrect MTP xact_len calculation
-
Video
- Add bufferless operation callback for dynamic frame generation with tud_video_prepare_payload_cb()
Host Stack
