vendor: deactivate de-selected altsetting's isochronous endpoints

2026-07-17T05:07:50Z

vendord_set_alt() aborted bulk/interrupt endpoints of the outgoing altsetting (stall/clear-stall) but only dropped the iso endpoints' tracking: an armed iso transfer stayed live in the dcd with its usbd claim held and no tracked handle to stop it, and its completion fired into an endpoint the class no longer recognizes. Reachable through the usbtest example's alt0 (bulk) <-> alt1 (iso) SET_INTERFACE switching. Track each selected iso endpoint's descriptor (points into the app's static descriptor set) and deactivate on de-selection: with the iso-alloc API re-activation is the abort/scrub primitive (resets ep_status, aborts the stale transfer); without it usbd_edpt_close does, and the next selection re-opens. Iso cannot be stalled like bulk/interrupt, hence the separate path. Build-verified: usbtest for stm32f072disco, ra4m1_ek, raspberry_pi_pico (iso-alloc) and ch32v307v_r1_1v0 (close API).

* 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.
