Steam Deck pass-through (design/steam-deck-passthrough-plan.md), code-complete + all CI checks green on Linux + adversarially reviewed; on-glass validation pending: - usbip/`vhci_hcd` virtual Deck transport (inject/linux/steam_usbip.rs) for non-SteamOS hosts (Bazzite/generic) — presents a real interface-2 USB Deck so Steam Input promotes it. In-process vhci attach (loopback OP_REQ_IMPORT handshake → sysfs attach) with a bounded `usbip`-CLI fallback; detach on drop. - Backed by a vendored, libusb-free trim of the `usbip` crate (crates/punktfunk-host/vendor/usbip-sim, MIT + NOTICE; host/cdc/hid + rusb/nusb removed; interrupt-IN paced by bInterval). - Selection ladder raw_gadget (SteamOS fast-path) → usbip (universal) → UHID, with PUNKTFUNK_STEAM_USBIP / PUNKTFUNK_USBIP_ATTACH knobs. - Shared Deck descriptors + the 0x83/0xAE feature contract + a Steam-accepted serial consolidated into steam_proto.rs; the raw_gadget backend reuses them. - Linux client leave-shortcuts: Ctrl+Alt+Shift+D + holding the escape chord (L1+R1+Start+Select) >=1.5s end the session (short press still exits fullscreen); the chord state resets across sessions. Also bundles in-progress work already staged in the tree: - host(kwin): xdg-output logical-geometry mapping so the KWin fake_input backend places absolute coordinates correctly under display scaling. - docs: design/README index entries + design/controller-only-mode.md.

Modifications by the punktfunk project:
|
|
- Removed the USB host modules (`src/host.rs`) and the `rusb`/`nusb` device
|
|
constructors in `src/lib.rs` (`with_rusb_*`, `with_nusb_*`, `new_from_host*`),
|
|
eliminating the libusb runtime dependency (which also broke `musl`).
|
|
- Removed the example helper interface handlers `src/cdc.rs` and `src/hid.rs`.
|
|
- Replaced the `rusb::Direction` re-export and `rusb::Version` conversions with
|
|
local definitions.
|
|
- Dropped the in-crate test modules (kept the library surface only).
|
|
- Paced interrupt/bulk IN endpoint transfers by bInterval in `device.rs`
|
|
`handle_urb` (so a simulated interrupt-IN mimics a real device's
|
|
NAK-until-bInterval behaviour rather than free-running over the loopback
|
|
link); added the tokio `time` feature for it.
|
|
|
|
Only the USB/IP server *simulation* path is retained: the device model, the
|
|
USB/IP wire protocol, and the `UsbInterfaceHandler` trait. The original MIT
