            Bug ID: 59891
           Summary: Elgato Stream Deck 7.4.2 does not work under Wine (app
                    fails to start, device does not render)
           Product: Wine
           Version: 11.11
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

The Elgato Stream Deck desktop software (Stream_Deck_7.4.2.22730.msi) does not
work under Wine. Making it run and drive a Stream Deck Mini (USB 0fd9:0063)
takes
several independent fixes across user32, dnsapi, winebus, and hidclass. This
bug
collects them.

Steps to reproduce:
1. Install Stream_Deck_7.4.2.22730.msi. Under Wine the install silently rolls
   back: the WiX firewall custom action returns E_NOTIMPL (there is no Windows
   Firewall COM under Wine), which triggers a full MSI rollback that removes
the
   payload. Workaround: set the prefix to Windows 10 (the MSI has a
   VersionNT >= Win10 launch condition) and pass DISABLEROLLBACK=1. The install
   symptom is also covered by bug 50849.
2. Launch StreamDeck.exe from a real desktop session.

Without the fixes below the app aborts during startup, and once it runs it
neither detects nor draws to the device.

Sub-issues and status:

1. user32: IsImmersiveProcess is a stub that does not return a value. The app
   calls it during startup and aborts. Fix: a stub returning FALSE (there are
no
   immersive processes under Wine), modelled on the existing IsWindowArranged
   stub. Submitted: https://gitlab.winehq.org/wine/wine/-/merge_requests/11199

2. dnsapi: DnsServiceConstructInstance and DnsServiceFreeInstance are
   unimplemented. The app calls them for service discovery and aborts. Fix:
   implement both (build and free a DNS_SERVICE_INSTANCE, no network), add the
   struct and prototypes to windns.h, and add a test. Submitted:
   https://gitlab.winehq.org/wine/wine/-/merge_requests/11200
   The app also calls DnsServiceRegister and DnsServiceResolve, which are still
   unimplemented and need separate work.

3. winebus: synthesized USB-HID devices do not expose the standard USB\Class_03
   compatible IDs (with subclass and protocol) that a real Windows USB-HID
device
   has. The app walks from the HID device to its USB parent with CM_Get_Parent
and
   validates those IDs, so it rejects the device and reports "no device found".
A
   fix that adds the USB-class compatible IDs is in progress; it needs to be
gated
   to the USB bus and take the subclass and protocol from the interface
   descriptor.

4. hidclass: WriteFile on a numbered HID output report returns one byte less
than
   the application submitted, because the report ID byte is subtracted from the
   transfer length. The app advances its per-key image upload by the WriteFile
   count, so the upload never progresses and the keys stay blank. Fix: return
the
   full report length, which matches Windows. Submitted:
   https://gitlab.winehq.org/wine/wine/-/merge_requests/11204

With all four applied the Stream Deck Mini is detected, controllable, and
renders
the correct image on every key.
