Queue correlated, volatile wake requests for the BTstack owner and expose
read-only completion state. Keep the controller chord, captured identity,
pairings, profiles, HD settings and existing wake burst unchanged.
Add Python API and wake CLI with bounded waits, explicit failure outcomes
and no automatic broadcast retries. Avoid importing SDL just to obtain
fixed sensor IDs so USB automation has clean output and no SDL dependency.
Windows libusb cannot control hub roots. Expose only INFO/WAKE on each
native child's existing vendor Interface 1 with isolated control state;
retain hub/HID drivers, descriptors and identities. Add safe sibling-aware
Windows discovery and a packaged Windows libusb runtime. Document manual
WinUSB binding to Interface 1 only and migrate examples to find_wake_pico.
Validate with 713 tests, 10 firmware/probe builds, Windows x64 wheel
resolution on Python 3.9/3.11, and a real child-interface wake burst on
Linux (2.03 s, no controller, no failures). Device/configuration descriptors,
serials and persistent state matched before/after. Physical Windows
hardware/driver operation remains unverified on this Linux workstation.
Keep native backend locking IRQ-permitting and service USB hardware from SRAM during BOOTSEL sampling. Add bounded input/control flight recording, root IN and EP0 snapshots, and masked-window handoff coverage. Record PC qualification and the remaining Switch stability limitations.
