enricobuehler	01266ff18d	feat(gamepad): SC2 Puck-dongle passthrough with the native 28DE:1304 topology ... Community-contributed round 5 of the Steam Controller 2 passthrough, reviewed + verified. A Puck-captured pad now presents the dongle's real seven-interface identity (CDC pair, four controller HID slots, management HID) instead of relabelling its reports as a wired 1302 — Steam's Puck feature dances (wireless_transport / esb/bond / 0xB4 slot status) get capture-shaped answers, and the wired identity's canned replies are corrected to the real captures (attribute count, string-attr framing, 0xF2 firmware info, bcdDevice nibble encoding). - new wire pref 10 = SteamController2Puck (Hello/Welcome byte; older peers degrade to Auto), selected by the Android capture link when the transport is a dongle, or by VID/PID in the degraded InputDevice path - TRITON_RDESC is now the captured numbered descriptor (mouse/keyboard lizard collections + per-id vendor reports); unnumbered framing made hidraw mangle feature report 2 and Steam eventually closed the device - interrupt-IN now queues sparse reports (battery/RSSI/wireless edges) instead of keeping latest-only, so a 250 Hz state packet can no longer erase them before the USB/IP poll observes them; EP0 SET_REPORT is split by wValue report type (OUTPUT parsed for rumble vs FEATURE) - vendored usbip-sim: config attributes/max-power, IAD prefix + BOS descriptor support, correct BCD minor.patch encoding (Deck's 0x0300/ 0x0200 values are nibble-zero, so its bytes are unchanged), and full-speed interrupt pacing in ms (was 8 kHz from the HS formula) - Triton feedback is serviced at 1 kHz while an SC2 backend exists so Steam's trackpad haptic writes reach the client unbatched Verified: clippy -D warnings + 319 host tests green on Linux, core wire tests green, Android kit/app compile + unit tests green. On-glass Puck retest owed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 20:47:52 +02:00
enricobuehler	6425edb8e4	fix(host): answer the Valve feature-GET dance properly — Steam dropped the virtual SC2 ... Tester-diagnosed: Steam's GetControllerInfo SETs a query (0x83 attributes / 0xAE string) and GETs the answer; the virtual SC2 answered EVERY get with a serial blob, so the 0x83 probe came back mistyped and Steam never adopted the pad ("it does nothing"). - triton_feature_reply(): the GET answer now echoes the LAST SET's command — the same validated state machine the virtual Deck ships — framed on feature report id 1 (SDL's send framing for this device): 0x83 → the Deck-shaped 9-attribute blob with the Triton's product id (0x1302) + per-instance unit id; 0xAE → the FVPF serial with the requested string-attribute tag; anything else reads back as an echo. Values beyond the product id mirror the Deck's hidraw capture (same firmware family) — swap in a physical-pad capture if Steam still balks. - Both legs track last_set and reply through the shared helper (the usbip EP0 handler and the UHID GET_REPORT path); the serial/unit-id helpers moved to triton_proto so the identities agree. - Each distinct GET command is info-logged once ("answering feature GET cmd=0x83") so the tester's journal shows the dance. Committed without the usual .21 verify round (user request — verify before push); --no-verify per the shared-tree fmt-hook false positive.

enricobuehler	d352e4e456	fix(android,host): SC2 first-on-glass fixes — UsbRequest reads + usbip transport ... First on-glass run (wired pad + Puck, NixOS host "miko") surfaced three things; all addressed: Android (the create→unplug flap at 255 ms, and the Puck showing nothing): - Read interrupt endpoints with UsbRequest/requestWait, not bulkTransfer — Android only supports bulk transactions on bulk endpoints, so reads returned the first buffered report and then -1 forever (tester-diagnosed). One IN request stays queued; OUT reports (Steam's forwarded haptics) are queued onto the reader thread, which is the single requestWait owner. Unplug detection is now sustained-silence (5 s), not a failure counter. - Wireless-status (0x46/0x79) is authoritative only through a Puck dongle: a WIRED pad truthfully reports "no radio link" and must not tear the slot down (this alone explained the wired flap's remove event). - Lizard-off confirmed working on-glass — framing unchanged. Host (Steam confirmed to ignore the UHID leg, Interface: -1 — the Deck story repeating): - triton_usbip.rs: the virtual SC2 now attaches via vhci_hcd as a REAL USB device, byte-matched to the tester's lsusb capture of the wired pad (28DE:1302, bcdDevice 3.07, class EF/02/01, Full Speed, one HID interface #0 with interrupt IN 0x81 / OUT 0x01, 64 B, bInterval 1, bcdHID 1.11, Valve strings; FVPF-prefixed serial so the 28DE conflict gate recognizes it as ours). Interrupt-IN mirrors the client's raw reports; interrupt-OUT captures Steam's haptic output reports (0x80 parsed for the 0xCA plane, everything forwarded raw); EP0 SET_REPORT features normalize to id-first framing and forward raw. - steam_usbip.rs: the attach choreography (in-process sysfs attach → usbip CLI fallback) extracted into a shared UsbipAttachment used by the Deck and the SC2 device models — behavior-identical for the Deck. - steam_controller2.rs: transport ladder usbip → UHID (the fallback now warns that Steam won't list it, with the modprobe vhci_hcd remedy). Verified: host 314 tests green on Linux (.21) incl. the new device-model units; on-box smoke attaches the virtual 28DE:1302 through vhci_hcd (real USB enumeration, not /devices/virtual) and tears down on drop. Owed: the tester's Steam-visibility check against the usbip leg + Android retest. (--no-verify: the fmt pre-commit/pre-push checks trip on ANOTHER session's uncommitted WIP in the shared tree; every file in this commit is rustfmt-clean and the committed tree passes cargo fmt --check.)
