    I have 3x Realtek RTL2832U usb DVB-T tuners in my MP1 TV Server. They appear as REALTEK DTV Filter with unique card IDs and device instance paths.

    After some time (weeks, months ?), in TV Server one of them changes to status unknown and re-appears with a new card ID and new device instance path. I know this matches up with the same entry in Device Manager, so it must be happening outside of MP. I've seen this previously when I unplug and re-plug the same tuner into a different USB port.

    Something is causing the device instance path to change when multiple usb tuners are used. Probably monthly / weekly Windows updates that require a reboot. (Win10 x64 - 1903). I'm using Realtek drivers v64.1.801.2012 as the detected MS drivers don't seem to work at all. Is anyone else using newer drivers with success? Version and DL link please?

    Can I force a specific usb tuner once seen to retain its device instance path and present consistently to TV Server as the same card?

    Is there an easy way in Device Manager and MP TV Server to rename and identify multiple hardware devices that are identical? Eg Card1, Card2, Card3 etc

    I don't think this issue is MP related but I can submit logs if requested. It would be a tough one to capture as I can't trigger it manually.

    Any help or advice is appreciated.
