I'm using an "old-fashioned" Windows 10 Tower PC with latest firmware (not a desktop but a desk-below) that is located below my desk. My problem is getting the camera connected and recognized by NX Tether 2.0. The camera always connects to the PC, i.e. the Z8 folder shows up with two files in it, one per memory card - I suppose. The issue is that NX Tether does not recognize the camera. The Windows plugin prompt can be turned off permanently b.t.w., which I have done.
I first tried the front USB-A connectors (which are connected to the mainboard via internal cabling rather than directly soldered to the mainboard) because they are the only ones accessible with the very short (and cheap?) Nikon cable UC-E24 - the front USB ports are 3.2 type (SS 5 = 5 Gbit).
I now tried the back USB 3.2 connectors requiring some body exercise with all the camera and scanning device attached (I'm using the Valoi easy35 camera attachment). It actually worked once or twice but I can't repeat it. I tried all USB 3.2 ports: SS 10 (10 Gbit), SS 5 (5 Gbit). None work repeatedly. The PC also has a 10 Gbit USB-C 3.2 port in the back which I cannot try with the Nikon UC-E24 cable because it is an A-C cable. I don't want to introduce another Unknown with a third-party USB-C to -C cable.
I openend a ticket with Nikon a few days ago, they haven't answered yet.
