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.
Preserve native frequency/amplitude timelines for DualSense PCM output,
remove the unsupported 64-frame path, and retain compatibility rumble for
other controllers. Use the validated 300 MHz sampling phase and restrict
non-bondable Classic discovery autoconnect to previously paired peers.
Buffer native-hub UART stdout and release USB IRQs around port-reset
callbacks. Add observer liveness and pre-SETUP root-response observations
without changing recovery behavior. Cover transport and haptics boundaries.
Record the user-accepted 0.108 trial: controls remained responsive and
rumble felt fine. Instrumentation changes timing; the disconnect root
cause and long-term reliability remain unqualified.
Validation: 624 tests, 11 affected firmware/probe builds, and on-device
concurrent USB and HD-auto-start checks. Private captures, generated
images, and unrelated working-tree files are intentionally excluded.
