    Hi Plugin developers,

    have you ever had the case that the pointers you found for a Memory Hook Plugin become invalid when you connect/disconnect USB devices?

    And do you know a solution for this?

    Here's what I did:
    I determined some pointers for Radial-G via Cheat Engine and built a plugin with these pointers. Then I installed the plugin into SimTools.
    Result: Game Engine, Game Dash and Game Vibe showed the expected values.

    I did all this with just an XBox controller connected to my PC.

    Then I turned on my USB hub, which has all my simulator components connected: Thrustmaster HOTAS Warthog, MFG Crosswind rudder pedals, 3 SaberTooth 2x32, Razer Tartarus.

    I restarted the SimTools components as well as the game, and this time none of the SimTools components showed any values.

    I retested again with turned-off USB hub, and everything worked again.

    Now I went back into Cheat Engine and did a pointer scan with turned-on USB hub.

    Result: None of the pointers that I previously found with turned-off USB hub are still valid when the hub is powered.

    I made exactly the same experience some time ago when I tried to build a plugin for Lunar Lander.

    Do you have any hints for me?

    Are you finding thumbstick values and not telemetry data? Or just not static pointers?

    I don‘t find stable pointers. Either they work with or without powered USB hub, but none of the found pointers work for both configurations.
