Add SuperSpeed descriptors to all bulk/interrupt class drivers and examples

2026-07-07T11:12:02Z

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).

Add core SuperSpeed device support

2026-07-07T02:46:25Z

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.

cdc_host: fix undeclared 'idx' when only LINE_CONTROL_ON_ENUM is defined

license: use SPDX identifiers for src/ headers (#3749)

2026-07-02T14:55:45Z

* 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 lines of duplicated boilerplate.

cdc_host: fix undeclared 'idx' when only LINE_CONTROL_ON_ENUM defined

2026-05-31T12:55:37Z

idx is used in the ENUM_SET_LINE_CONTROL path guarded by CFG_TUH_CDC_LINE_CONTROL_ON_ENUM, but was declared only under CFG_TUH_CDC_LINE_CODING_ON_ENUM. Defining LINE_CONTROL_ON_ENUM without LINE_CODING_ON_ENUM therefore failed to compile with an undeclared identifier. Guard the declaration under either macro. Signed-off-by: Andrew Leech
