FIX - How to use the Ikarus Easy Commander USB controller in Windows 10/11

  • Hey all,

    Ever since upgrading from Windows 7, I could no longer use my old USB Easy Commander RC controller made by Ikarus (model #3015010) and sold with their Easyfly simulator.
    Windows would throw an error message: "Unknown USB Device (Device Failed Enumeration)"

    Although options exist to connect a real controller to the sim, I always liked the idea of having this easy controller within reach to scratch the RC urge in the winter months.
    By coincidence, I came across this blogpost that describes how to make the old controller work in Windows 10/11.

    Solution by Kannekens

    The blogpost explains how to add a SkipBOSDescriptorQuery binary value of 01 00 00 00 to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\040204022273 in regedit.exe.

    Steps

    • Open regedit.exe.
    • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\usbflags\.
    • If 040204022273 does not exist, create it.
    • Inside that folder, create a new Binary Value named SkipBOSDescriptorQuery.
    • Set the value to 01 00 00 00. (Alternatively, you can try the value 10 as well)
    • Restart your PC.

    Putting this here as it might help others too.

    Regards,
    Sylvain
