### What winebus reports the USB class compatible IDs (`USB\Class_03&SubClass_xx&Prot_y` and the two shorter forms) for USB devices, alongside the existing WINEBUS\\WINE_COMP_HID id. wineusb.sys already reports these IDs in this format for the devices it enumerates (dlls/wineusb.sys/wineusb.c, get_compatible_ids). winebus does not, so its synthesized USB-HID devices look different from a real Windows USB-HID device to any application that validates the USB parent. This makes winebus do the same. ### Why On Windows the USB parent carries these IDs and applications validate them through `CM_Get_Parent` or `SetupDi`. Wine omits them, so those applications fail. The Elgato Stream Deck app is one concrete case: it reports "no device found" for a connected Stream Deck Mini and recognises it once the IDs are present. winebus has no separate USB interface device to host the IDs. On a real stack the interface PDO from usbccgp is the HID device's parent; under winebus the IDs are reported on the HID device itself, which is the device an application reaches from the HID node. Only the hosting device differs from Windows; the IDs and their format match what wineusb already reports. ### How The interface class, subclass and protocol come from the udev usb_interface node (bInterfaceClass, bInterfaceSubClass, bInterfaceProtocol). get_compatible_ids formats them the same way wineusb.sys does, for USB devices that carry interface information, and keeps the existing ids ahead of them so driver binding is unchanged. ### Testing No automated test: winebus has no unit harness for the udev backend (the dinput HID test drives its own mock bus and never reaches this path), and the IDs derive from live sysfs values. Verified by hand: with the change the USB parent's CompatibleIds gains `USB\Class_03&SubClass_00&Prot_00` and the two shorter forms (read live from sysfs) alongside the existing WINE_COMP_HID, and the Elgato Stream Deck app then detects a connected Stream Deck Mini that it otherwise rejects.
