Disabling USB keyboard after reboot

I used SetupDiSetClassInstallParams and SetupDiCallClassInstaller to disable specific USB device.

SP_PROPCHANGE_PARAMS params;

params.ClassInstallHeader.cbSize = sizeof(SP_CLASSINSTALL_HEADER);
params.ClassInstallHeader.InstallFunction = DIF_PROPERTYCHANGE;
params.StateChange = DICS_DISABLE;

// SP_DEVINFO_DATA - Info.DevInfoData 
if (!SetupDiSetClassInstallParams(hDevInfo, &(Info.DevInfoData),&params.ClassInstallHeader, sizeof(params))) {
    Error = GetLastError();
    return Error;
}

if (!SetupDiCallClassInstaller(DIF_PROPERTYCHANGE, hDevInfo, &(Info.DevInfoData))) {
    Error = GetLastError(); // error here
}

This approach works to all devices, except keyboard. If i try to disable her this way ERROR_NOT_DISABLEABLE returned. But after reboot keyboard will be disabled.

Before disabling, flags DN_DISABLEABLE and DN_REMOVABLE seted for this device, checked by function CM_Get_DevNode_Status. What i am doing wrong?

Solution

  • This device don't support disabling
