fix(host): release spinlock in tuh_deinit to fix multi-rebuild panic

2026-06-21T09:46:26Z

tuh_rhport_init() calls osal_spin_init(&_usbh_spin), which under OPT_OS_PICO claims a hardware spinlock via critical_section_init(). There was no osal_spin_deinit(), so tuh_deinit() never released it: every host init/deinit cycle leaked one spinlock. RP2350 has a small spinlock pool, so a few usb_host rebuilds exhaust it and hw_claim_unused_from_range() panics (the long-standing "crashes on the 4th rebuild" bug). Add osal_spin_deinit() to all OSAL backends (critical_section_deinit for pico; no-op for none/freertos) and call it in tuh_deinit(). Verified 20/20 deinit+rebuild cycles on RP2350-Zero and Waveshare RP2350-USB-A (previously panicked on the 4th). Co-Authored-By: Claude Opus 4.8 (1M context)

Implement asynchronous control transfer queuing for USB host stack

2026-05-29T09:16:21Z

- Added a pending FIFO queue for asynchronous control transfers when the active slot is busy. - Introduced `control_xfer_dispatch_pending` to handle queued transfers on slot availability. - Improved synchronization for blocking and non-blocking transfer modes, preventing deadlocks in RTOS. - Refactored and renamed related functions for clarity and consistency. - Enhanced error handling and callback invocation for failed or stale transfers.

osal add osal_task_get_current_handle()
