Patch for Vive Trackers support

Hi!

My name is Andrey.
Unreal engine 4.18.3
SteamVR
5 HTC truckers + hmd + 2 controllers.
I have a problem: the controller triggers spontaneously shut down. when debugging I get, sometimes, that there are more than two controllers attached (however there are only two controllers). who worked with openVR, gettrackeddeviceclass (id)?
thank you for any help.
