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. feat: add MIDI 2.0 Device class driver (USB-MIDI 2.0) 2026-05-12T14:07:44Z Saulo Veríssimo sauloverissimo@gmail.com 2026-03-25T02:37:48Z urn:sha1:bc8ce76ae800b312b4d3ef591cc42e8726e68d7f 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 fix usbd control to support wLength hack 2026-05-04T06:39:39Z hathach thach@tinyusb.org 2026-05-04T06:39:39Z urn:sha1:e954302c103b4fc6870c6914945e6da1f62f6423 refactor: replace `tu_edpt_state_t` struct with `uint8_t` and update all endpoint state handling methods and accesses 2026-05-04T05:11:03Z hathach thach@tinyusb.org 2026-05-04T04:19:26Z urn:sha1:9d68ed65f7200f155f01416b332c5e9f2340a8b2 refactor `usbd.c`: extract `process_std_device_request` for clarity 2026-05-04T03:29:29Z hathach thach@tinyusb.org 2026-05-04T03:29:29Z urn:sha1:a5e9ce5fbb300702d04c47c7c06436396912d3d6 refactor `usbd.c`: centralize control transfer state management into `_usbd_dev` structure and remove `usbd_control_reset` 2026-05-04T01:55:08Z hathach thach@tinyusb.org 2026-04-29T15:23:32Z urn:sha1:eb66712196b54ff5dcf39df020fb0cad72e853d0 deprecated `usbd_control.c` and merge its functionality into `usbd.c` 2026-04-29T10:27:59Z hathach thach@tinyusb.org 2026-04-29T10:27:59Z urn:sha1:9d3ad336bfad062fa1e6f6d63feb97a9851cc9e1 remove duplicated tu_le16toh since we have converted the endian when setup. 2026-04-17T10:39:56Z Fan DANG i@dang.fan 2026-04-17T10:39:56Z urn:sha1:5939831f17272571911d089508b458f496a4cc62 Simplify tud_task() like in tuh_task() 2026-03-22T13:12:50Z Cédric Berger cedric@precidata.com 2026-03-22T13:12:50Z urn:sha1:db7722dee8410f27f6ea7dfcbfaf44e2f88cccf3 replace printer_to_hid example with printer_to_cdc example 2026-03-06T10:22:38Z hathach thach@tinyusb.org 2026-03-06T10:22:38Z urn:sha1:73cd53129529f2dce70072953bfd50ec9dc6b8ea fix printer GET_DEVICE_ID request weird wIndex (interface high, alt low)
