Class drivers: skip and account the SS endpoint companion descriptor in
every descriptor walk (hid, midi, midi2, ecm_rndis, printer, mtp, usbtmc),
via a shared usbd_skip_ss_ep_companion() helper in usbd_pvt.h (cdc/ncm
already handled; vendor/dfu naturally tolerant). usbtmc buffer grows to
1024 at SS to satisfy its packet-multiple assert. bth/audio/video are left
FS/HS-only (ISO-centric; ISO is unsupported on the CH569 dcd).
usbd.h: new SS template macros TUD_HID_SS_DESCRIPTOR(+INOUT),
TUD_MIDI_SS_DESCRIPTOR (+ DESC_EP_SS part), TUD_MIDI2_DESC_ALT1_EP_SS,
TUD_PRINTER_SS_DESCRIPTOR, TUD_MTP_SS_DESCRIPTOR,
TUD_USBTMC_BULK_SS_DESCRIPTORS/INT_SS_DESCRIPTOR, with _SS_DESC_LEN
counterparts (bulk endpoints hardcode 1024, companion after every EP).
Examples: 17 bulk/interrupt examples gain the full SS descriptor set
(EP0 512/64 clamp, SS device descriptor bcdUSB 3.20 mps0=2^9, SS config
with companions, BOS caps, speed-switched callbacks): cdc_dual_ports,
cdc_msc_freertos, dfu, dfu_runtime, dynamic_configuration,
hid_boot_interface, hid_composite(+freertos), hid_generic_inout,
hid_multiple_interface, midi_test(+freertos), midi2_device, msc_dual_lun,
mtp, printer_to_cdc, usbtmc, webusb_serial. msc_dual_lun is un-skipped for
CH569 using read-only flash disks (16KB RAM can't hold two 8KB RAM disks,
same as ch32v10x/v20x boards).
Validation: full example sweep green for hydrausb3_v1 (SPEED=super, 19
device ELFs) and raspberry_pi_pico; wTotalLength == sizeof() verified for
every SS configuration array in the built ELFs; ceedling 65/65;
pre-commit clean; code-size delta +0.0% on rp2040 (SS code folds out on
non-SS builds).

- TUD_CDC_NCM_SS_DESCRIPTOR template (bulk 1024 + endpoint companions)
and companion handling in netd_open (notification endpoint skip,
bulk pair drv_len)
- net_lwip_webserver: SS device/config/BOS descriptors for the NCM
build, CH569 added to the LWIP_HIGH_THROUGHPUT tier (builds lwiperf).
The 16 KB RAMS cannot hold lwIP: heap and pools go to the 32 KB RAMX
via LWIP_DECLARE_MEMORY_ALIGNED (arch/cc.h), with a 6-pbuf pool /
6*MSS window and a 3 KB dcd bounce pool to fit (RAMX 92%)
- CH569 dcd fixes found while bringing this up: TMR0 counts only 26
bits, so the previous 1 s fallback CNT_END (120e6 > 2^26) silently
never expired - use 0.55 s per phase; make link busy-waits in
usb30_hw_init best-effort so a stuck-BUSY teardown state cannot
abort re-initialization half way
Builds clean (full ch56x example sweep); NOT yet hardware-validated:
the rig's WCH-LinkE stopped completing flash writes mid-session (reads
and erases fine), leaving the board without firmware - iperf numbers
pending physical probe/board recovery.

Groundwork for TinyUSB's first SuperSpeed port (WCH CH569):
- TUSB_SPEED_SUPER, OPT_MODE_SUPER_SPEED, TUD_OPT_SUPER_SPEED and
TUP_RHPORT_SUPERSPEED capability plumbing
- Allow CFG_TUD_ENDPOINT0_SIZE 512 on SS builds; EP0 control transfers
chunk at the runtime link speed (512 at SS, 64 on USB2 fallback)
- Handle SET_SEL, SET_ISOCH_DELAY and U1/U2_ENABLE feature requests
- Tolerate SS endpoint companion descriptors in usbd_open_edpt_pair,
cdcd_open and mscd_open interface parsing
- SS descriptor types/structs and template macros: endpoint companion,
BOS USB2-extension + SuperSpeed capability, SS config and
CDC/MSC/vendor SS variants (bulk fixed at 1024)
- cdc_msc example: SS device/config/BOS descriptors, speed-aware sizes
- Unit tests: SS endpoint validation, companion-tolerant endpoint pair
open, SET_SEL, SET_ISOCH_DELAY
All SS paths compile out when disabled: verified 0-byte code-size delta
on stm32f407disco (MinSizeRel) vs master; 65/65 unit tests pass.

* license: use SPDX identifiers for src/ headers
Replace the full ~20-line MIT license boilerplate on every src/ file with a
two-line SPDX tag (SPDX-FileCopyrightText + SPDX-License-Identifier), following
the REUSE convention used by CircuitPython and the Linux kernel. Removes ~3500

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.

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)

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

tud_descriptor_other_speed_configuration_cb()
|
|
for the Keil
compiler for the callback functions:
* tud_descriptor_bos_cb()
* tud_vendor_control_xfer_cb()
* tud_mount_cb()
* tud_umount_cb()
* tud_suspend_cb()
* tud_resume_cb()
Without the fix for the first two functions, the USB device won't enumerate properly, if
the device makes use of a BOS description. For example when using a Microsoft OS 2.0
platform capability descriptor to set a specific Device Interface GUID for WinUSB.
The fix for the other four functions were added, because it's probably just a matter of
time before someone runs into the same problem with those callback functions.
