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

Add Host example that receives UMP from a MIDI 2.0 Device via PIO-USB
and displays received messages on a SSD1306 OLED (I2C, 128x64).
Features:
- Boot checklist on display (PWR, TinyUSB, USB bus, Device, Descriptor,
Alt Setting UMP, Mount, Receiving)
- Decode and display all MIDI 2.0 Channel Voice messages
- PIO-USB Host on rhport 1 (GP12/GP13 for Waveshare RP2350-USB-A)
- SSD1306 display via I2C0 (GP4=SDA, GP5=SCL)
Also add board definition for Waveshare RP2350-USB-A.
Tested: Waveshare RP2350-USB-A (Host) receiving UMP from Raspberry Pi
Pico (Device) via USB cable, notes displayed on SSD1306 OLED

Add Device example that plays Twinkle Twinkle Little Star using native
UMP format. Demonstrates all MIDI 2.0 Channel Voice message types:
16-bit velocity, 32-bit CC, 32-bit pitch bend, 32-bit channel/poly
pressure, per-note management, program change with bank select, and
JR timestamps.
USB descriptor exposes both Alt Setting 0 (MIDI 1.0) and Alt Setting 1
(UMP) per USB-MIDI 2.0 specification.
Tested on: Raspberry Pi Pico (RP2040), Linux (ALSA), Windows (MIDI
Services)

Add unit tests for MIDI 2.0 drivers:
- Device: UMP word count (all 16 message types), descriptor macro
validation (length, byte layout, alt settings, endpoints),
CS endpoint subtypes, traversal integrity
- Host: UMP word count, callback struct validation, CS endpoint
subtypes
Also add Sphinx documentation for MIDI 2.0 class drivers (Device
and Host API reference, lifecycle, configuration, examples).
Tests: 60/60 PASS (FIFO 26/26, USBD 5/5, MIDI2 Device 18/18,
MIDI2 Host 6/6, USBD internal 5/5)

Add native USB-MIDI 2.0 Host class driver to TinyUSB. Implements
reactive architecture: enumerate, detect MIDI 2.0 capability, inform
application via callbacks.
Driver features:
- Parse both Alt Setting 0 (MIDI 1.0) and Alt Setting 1 (UMP)
- Detect bcdMSC version from descriptor
- Auto-select highest protocol (Alt 1 preferred if available)
- UMP read/write via endpoint streams
- Proper Audio Control interface skip (loop-based, following
midi_host.c pattern)
- Endpoint open with tuh_edpt_open/tu_edpt_stream_open/clear
- usbh_driver_set_config_complete for USBH state machine
- Handle Audio Control itf_num in set_config gracefully
- 5 weak callback stubs (descriptor, mount, unmount, rx, tx)
Build system:
- Register midih2_* in usbh.c driver table
- Add midi2_host.h include to tusb.h
- Add CFG_TUH_MIDI2_LOG_LEVEL to tusb_option.h
All changes guarded by #if CFG_TUH_MIDI2 (default 0). Zero impact on
existing drivers and examples.
Tested: Waveshare RP2350-USB-A (Host) receiving UMP from Raspberry Pi
Pico (Device) via PIO-USB, board-to-board

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

nrf5x: request HFCLK in USB_EVT_READY to fix post-SoftDevice deadlock
|
|
USB_EVT_DETECTED runs hfclk_enable() which, when SoftDevice is not yet
enabled, starts HFXO via direct CLOCK register access. After
sd_softdevice_enable() takes over CLOCK, HFXO is physically off again
and SD's HFCLK reference count is 0.
If USB_EVT_READY is fired post-SD (e.g. on nRF52 via Bluefruit's
usb_softdevice_post_enable() when the pre-SD nrfx_power READY callback
didn't get to run before nrfx_power was uninited), the wait loop
'while (!hfclk_running()) {}' calls sd_clock_hfclk_is_running() which
returns false forever -> deadlock that blocks both USB enumeration and
any further app code on the calling thread.
Call hfclk_enable() right before the wait so HFCLK is requested in
whichever context (SD or direct) is current. hfclk_enable() is
idempotent.
Reproduces reliably with bleuart on Feather nRF52840 Express flashed
via JLink: chip wedges in sd_clock_hfclk_is_running SVC, no USB
enumeration, no BLE advertising. With the fix, USB enumerates and BLE
advertises as expected.

According to NCM standard 7.2.7, the device should tell the host its maximum size of NTB. Implement SetNtbInputSize according to it.
Without this commit, some OS may failed to enumerate the NCM device (e.g., IOS 26).
