class/vendor: portability + robustness fixes for int/iso/alt support

2026-07-03T01:57:29Z

- Isochronous endpoints are reserved through TUP_DCD_EDPT_ISO_ALLOC-guarded helpers with a usbd_edpt_open fallback (mirrors audio), so ports without the iso alloc API (lpc_ip3511, rusb2) enumerate instead of failing open. - #error when EP_ISO_* is set without ALT_SETTINGS (iso must live in a non-zero altsetting per USB 2.0 5.6.3); the non-alt open path no longer silently treats an iso endpoint as bulk. - Non-buffered bulk read/write gain the 'ep > 0' guard the int/iso APIs have, so they cannot claim EP0 while an altsetting without a bulk ep is selected. - find_vendor_itf uses p_itf_desc (not the ep fields) to detect a free slot under ALT_SETTINGS, where an interface parked in the empty alt 0 has all ep fields 0; fixes slot aliasing with CFG_TUD_VENDOR > 1. - vendord_set_alt validates the altsetting exists before mutating state (rollback safety) and stall/clears interrupt endpoints only for the enabled direction. - vendord_open rejects an endpoint address reused across altsettings with a different type/MPS (opened once), closing a misconfig + buffer overflow.

class/vendor: isochronous endpoints + alternate setting support

2026-07-02T15:58:36Z

CFG_TUD_VENDOR_EP_ISO_OUT/IN (default 0) add an isochronous endpoint per direction with the same non-buffered API shape as the interrupt pair (tud_vendor_n_iso_read_xfer / tud_vendor_n_iso_write + weak iso_rx/tx_cb), buffers sized by CFG_TUD_VENDOR_EP_ISO_OUT/IN_BUFSIZE. CFG_TUD_VENDOR_ALT_SETTINGS (default 0, non-buffered mode only) lets the vendor interface carry multiple altsettings: vendord consumes them all, answers GET_INTERFACE and performs SET_INTERFACE via a new internal vendord_control_xfer_cb (registered in usbd's driver table; everything else still delegates to the app's tud_vendor_control_xfer_cb). Endpoints are hardware-opened exactly once at vendord_open: dcds with a linear FIFO allocator (dwc2: TUP_DCD_EDPT_ISO_ALLOC, where usbd_edpt_close is a no-op and every re-open leaks FIFO space) cannot close/re-open endpoints dynamically. Selecting an altsetting only re-targets the API: bulk/interrupt endpoints get a stall+clear-stall cycle, which portably aborts any in-flight transfer and resets the data toggle to DATA0 as SET_INTERFACE requires; isochronous endpoints are FIFO-allocated at open and (re)activated on selection. Motivated by the usbtest example (Linux usbtest iso cases 15/16/22/23, which also drives 256 consecutive SET_INTERFACE cycles in its ch9 case); alt 0 without endpoints satisfies USB 2.0 5.6.3 for iso devices.

class/vendor: optional interrupt endpoints (CFG_TUD_VENDOR_EP_INT_OUT/IN)

2026-07-02T15:06:22Z

The vendor interface may carry an interrupt OUT and/or interrupt IN endpoint alongside the bulk pair, each direction gated separately by CFG_TUD_VENDOR_EP_INT_OUT / CFG_TUD_VENDOR_EP_INT_IN (default 0, no cost when disabled) with CFG_TUD_VENDOR_EP_INT_OUT_BUFSIZE / CFG_TUD_VENDOR_EP_INT_IN_BUFSIZE (default 64) sizing the dedicated endpoint buffers; endpoint max packet size is checked at open. Interrupt endpoints are non-buffered: tud_vendor_n_int_read_xfer() arms the OUT endpoint one packet at a time (delivered via the new weak tud_vendor_int_rx_cb, no automatic re-arm), tud_vendor_n_int_write() is a direct transfer completing into tud_vendor_int_tx_cb. Motivated by the usbtest example (Linux usbtest interrupt cases 25/26) but generally useful for vendor protocols with a side channel.

* 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.
