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