device: clamp EP0 OUT data copy to the control transfer buffer (#3705)

2026-06-16T10:36:17Z

* device: clamp EP0 OUT data copy to the control transfer buffer usbd_control_xfer_cb() copied xferred_bytes from the EP0 bounce buffer into the requester's buffer with no bound. A non-compliant host that sends an OUT data packet larger than the control transfer's data_len (= min(len, wLength), the buffer capacity) would overflow that buffer and over-count total_xferred. Clamp xferred_bytes to the remaining buffer space before the memcpy and accounting.

midi2: align descriptors with USB-MIDI 2.0 spec

2026-05-12T14:07:45Z

Brings the MIDI 2.0 device driver into full conformance with USB Device Class Definition for MIDI Devices v2.0 (USB-IF, May 2020). - Alt 1 MS Interface Header wTotalLength now reports 0x0007 per Table 5-2 ("set to match bLength"), replacing the prior 0x0011 carried over from USB-MIDI 1.0 conventions. - GET_DESCRIPTOR class request now validates bmRequestType direction, type and recipient plus wIndex and wValue high byte per Section 6. - iBlockItem in the default Group Terminal Block is driven by CFG_TUD_MIDI2_BLOCK_STRIDX so applications can attach a UI string descriptor to the block per Table 5-6. - UMP word byte order assumption (little-endian host per Section 3.2.2) is documented inline so future big-endian ports know where to wrap access with tu_htole32 / tu_le32toh. Validated on RP2040 and ESP32-P4 under Linux kernel 6.17: lsusb -v reports wTotalLength = 0x0007 on Alt 1 MS Header (raw bytes 07 24 01 00 02 07 00). amidi -l enumerates Group Terminals exposed via the class-specific GET_DESCRIPTOR response.

fix: address PR review feedback for MIDI 2.0 drivers

2026-05-12T14:07:44Z

Host driver (midi2_host.c): - midih2_open() now returns actual parsed length instead of max_len, preventing composite device interface conflicts - Parsers (alt0/alt1) refactored to return const uint8_t* end pointer following midi_host.c switch/case pattern - Alt 1 CS Endpoint now parses MIDI 2.0 layout (bNumGrpTrmBlk at offset 3 with MIDI_CS_ENDPOINT_GENERAL_2_0 subtype check) instead of reusing MIDI 1.0 struct (bNumEmbMIDIJack) - midih2_set_config() now issues SET_INTERFACE control request via tuh_interface_set() before completing configuration. Falls back to alt 0 if SET_INTERFACE fails - Extracted midih2_set_config_complete() and midih2_set_interface_cb() for async SET_INTERFACE handling Device driver (midi2_device.c): - midi2d_open() skip loop now checks bInterfaceNumber, stopping at interfaces that belong to other functions in composite devices - SET_INTERFACE handler now rejects alt > 1 (returns false/stall) - Named constants for GTB descriptor types and MIDI protocol values Descriptor macros (usbd.h): - TUD_MIDI2_DESC_ALT1_HEAD: iInterface set to 0 (consistent with Alt 0), wTotalLength now uses TUD_MIDI2_DESC_ALT1_CS_LEN to cover all Alt 1 class-specific descriptors - TUD_MIDI2_DESC_ALT1_EP: now accepts GTB ID list via variadic args, emitting complete CS endpoint descriptor Host example: - CMakeLists.txt restricted to rp2040 family (display.c requires Pico SDK headers) - display.c: null terminator after strncpy in log scroll Documentation: - class_drivers.rst updated to reflect SET_INTERFACE behavior and auto-select with fallback Addresses: Codex P1 (#1, #2, #3), Copilot (#4-#9)

feat: add MIDI 2.0 Device class driver (USB-MIDI 2.0)

2026-05-12T14:07:44Z

Add native USB-MIDI 2.0 Device class driver to TinyUSB. Implements the USB-MIDI 2.0 specification with both Alt Setting 0 (MIDI 1.0 fallback) and Alt Setting 1 (UMP native) descriptor support. Driver features: - UMP (Universal MIDI Packet) read/write with atomic message framing - Protocol negotiation: Endpoint Discovery, Config Request/Notify, Function Block Discovery (embedded in driver) - Group Terminal Block descriptor via GET_DESCRIPTOR - Alt Setting switch handler with endpoint re-arm - Static allocation, no dynamic memory, ISR-safe Build system: - Register midi2d_* in usbd.c driver table - Add TUD_MIDI2_DESCRIPTOR macros to usbd.h - Add config defaults (CFG_TUD_MIDI2_*) to tusb_option.h - Add midi2_ump_word_count() to midi.h (shared by Device and Host) - Add midi2_device.c/h to family.cmake and CMakeLists.txt - Add midi2_device.h include to tusb.h All changes guarded by #if CFG_TUD_MIDI2 (default 0). Zero impact on existing drivers and examples. Tested: Raspberry Pi Pico (RP2040), Linux ALSA, Windows MIDI Services
