Steam Input only adopts the virtual Steam Deck controller when it arrives as a real USB device (raw_gadget or usbip/vhci transports); the UHID fallback has no USB interface and Steam ignores it. On a stock host neither precondition for usbip held: vhci-hcd isn't loaded, and its sysfs attach/detach files are root-only while the host runs as a user service — so every session silently fell back to UHID and 'no controller appears on the host' (live-debugged 2026-07-08: client events all arrived, the pad existed, Steam just refused it). Ship both preconditions with the host packages: * modules-load.d/punktfunk.conf loads vhci-hcd at boot (rpm/deb/arch; Bazzite gets it via the RPM payload + a modprobe in the sysext post-merge hook) * a udev rule in 60-punktfunk.rules grants the input group write on vhci_hcd's attach/detach whenever the device appears Verified end-to-end on a live host: usbip in-process attach, hid-steam binds all three interfaces, 'Steam Deck' + motion evdev appear, and Steam adopts the pad (client-mode grab + its own virtual X360 emission).
