Track base pointer to bd379e07 (usbhubd debounce/reset-wait/U0-wait/
wHubDelay + SET_ISOCH_DELAY, HubDescriptorV3 device_removable fix).
USB-IMPLEMENTATION-PLAN.md: P3-A marked CORE COMPLETE with the full
Linux equivalence inventory and documented follow-ups (USB 2.0 bitmaps,
SS.Inactive warm-reset loop, multi-TT, hub LPM). Hub gap-table row
updated (249 -> ~700 LoC with Linux state machine).
HARDWARE-VALIDATION-MATRIX.md: hub row updated — enumeration core
complete with 14 unit tests; runtime hub proof tracked under P8-B.

| USB storage (BOT) | ✅ | 🔲 | usbscsid autospawn + bounded sector readback proven (test-usb-storage-qemu.sh); guest-side write verify open |
| USB hub (non-root) | 🔲 | 🔲 | P3-A enumeration core complete (debounce/reset-wait/U0-wait/wHubDelay, 14 unit tests); runtime hub proof pending (P8-B test-usb-hub-qemu.sh) |
| GPU/Display | |||
| VESA | ✅ | 🔲 | QEMU framebuffer works |
| virtio-gpu | ✅ | N/A | 2D only, QEMU |
| CPU/Power | |||
