skill: add usb-sniffer — wire-level capture with the ataradov hardware tap

2026-07-17T10:32:47Z

Fourth view in the USB debugging toolset (usbmon = host URBs, usb-debug = host reasoning, usb-target-debug = device firmware, usb-sniffer = what actually crossed D+/D-). Covers the ataradov/usb-sniffer analyzer: headless pcapng capture (--speed ls/fs/hs, --fold, --limit self-exit), Wireshark/tshark analysis recipes, and the wire realities that bite: downstream broadcast, sniffer self-capture noise, xHCI devnum != wire address, tap-point-dependent reset visibility (hub choreography anchors), FS-behind-HS-hub splits. Every recipe hardware-validated on the rig, including the capture-window floor (a 3 s window provably misses the enumeration ladder; 3M packets minimum). Two udev files with distinct audiences, not one: - examples/device/99-tinyusb-examples.rules (renamed from 99-tinyusb.rules): the user-facing rules the examples need — cafe VID access, hidraw, the ModemManager blacklist, a couple of board probes. getting_started.rst, the webusb_serial README and its source comment point here. - tools/88-tinyusb.rules: the HIL rig's private probe/analyzer allowlist, now with the sniffer (6666:6620 + blank FX2LP 04b4:8613). Installed on the rig only; the usb-sniffer skill references it.
