APC40 mk2 disconnects from MIDI Remote on Windows 10 in Nuendo

Am experiencing a disconnect after a few minutes with a newly created APC 40mk2 MIDI remote device in Nuendo 12. Only happens on Windows 10, works fine on the Mac. Steinberg tech has provided me with a few things to try, such as disabling all USB devices from power management, but no luck. Has anyone solved this problem?
