sysview: instrument usbd/usbh, dcd/hcd and class-driver call sites

2026-09-03T21:21:57Z

Level 2 marks the stack's task-side entry points (tud_task/tuh_task inner loop, usbd_edpt_xfer, control transfers); level 3 adds the class drivers (cdc, msc) and the rp2040 dcd/hcd as the reference portable layer. All call sites compile away below their level.

sysview: record USB interrupt enter/exit (level 1)

2026-09-03T21:21:57Z

tusb_int_handler() brackets the whole USB interrupt with SystemView ISR enter/exit records, honouring its in_isr argument so a handler deferred to task context is not recorded as an interrupt. usbd.h/usbh.h expose the level-1 hooks the handler needs.

USBH: fail enumeration cleanly after disconnect

2026-09-02T13:21:41Z

A disconnect can close endpoint zero after an enumeration control stage completes but before USBH submits the next stage or request. HCD submission then legitimately returns false; treating that result as an invariant violation asserts during rapid replug and can leave enumeration unfinished. Complete an in-progress control request as failed when its DATA or status stage cannot be submitted. Propagate submission failures from every asynchronous enumeration continuation and finish enumeration through the normal failure cleanup path. This keeps controller teardown races out of assertions without fabricating a successful transfer. Validated by interrupting enumeration during rapid STM32U5A5 replug tests with DWC2 DMA and slave modes.

bound endpoint number in tu_bind_driver_to_ep_itf

propagate the endpoint-bound failure on the host path

2026-09-01T08:41:53Z

tu_bind_driver_to_ep_itf() now returns false when ep_num >= CFG_TUH_ENDPOINT_MAX, but the host caller ignores that result and continues enumeration. Configurations such as host/bare_api set the limit to 8, while valid USB devices may use endpoints 8–15. A recognized class can therefore continue and later index ep_status[epnum] or ep2drv[epnum] out of bounds. Wrap this call in TU_ASSERT(...), as the device path already does, so parsing fails immediately. Signed-off-by: HiFiPHile

vendor: remove the obsolete host vendor driver

2026-08-21T04:06:14Z

vendor_host.c/.h implemented a CFG_TUH_VENDOR class driver that no example, board or test ever enabled: usbh's driver table entry was compiled out everywhere, and the six tusb_config.h files that mentioned the macro all set it to 0. Maintainer call - dead code, not a shrinking of supported classes. Removes the sources, the usbh driver-table entry, the CFG_TUH_VENDOR default in tusb_option.h, the tusb.h include, both build-system source lists, the rp2040 family.cmake entry and the IAR project template rows.
