**Hardware-dependent or design decisions:**
- Real hardware validation: no controller tested outside QEMU
- Hot-plug stress testing
- Storage I/O validation (read/write to block device)
- Storage write validation (bounded sector-0 readback proof now exists in QEMU via `test-usb-storage-qemu.sh`, but guest-side write verification to the USB-backed block device is still open)
- usbhubd 1-second polling fallback (only exercisable with real hub hardware)
- Modern USB scope decision: device mode / USB-C / PD
