Hi there. I have read every relevant forum I can find about this, but haven't come to a solution. I've also posted this on Steinberg forums just now. I’d be eternally grateful for any ideas or fixes :D
Software is Cubase 10.5 Pro, Windows 10.

Long story short, I have a Behringer X-Touch and two extenders. All 3 show up under Midi/Midi Port Setup. When I go to Midi/Remote Devices and add Mackie Control, the main unit connects fine. Then I add Mackie Control 2, and the first extender (either one I choose) connects fine. But when I add Mackie Control 3 and try to connect the other extender, it thinks I'm trying to connect the first extender again (you can hear the inner mechanics of that device get triggered), leaving me with 2 out of 3 units responding to Cubase properly. The dropdown boxes initially show you what you want to see, but after applying and clicking between Mackie Control 2 and 3, they end up showing the same device.

I have tried renaming the extenders to be unique from each other in Midi Port Setup ‘Show as’ column (see my screenshots where I've called them A and B), but this has no effect on the issue mentioned above - even though I thought that would be how to solve it. And you can’t rename them in the ‘Port System Name’ column at all.

I have also tried using USBdeview utility to ‘forget’ the midi ports/driver installations, and connect the devices fresh, as well as trying different USB ports (and not using the X-touch hubs, etc.) But however I connect these devices, they always just show up as:
X-Touch
X-Touch-Ext
X-Touch-Ext
… without a unique delineation between the last two.

I also tried using USBdeview to change the 'Friendly name' data of each device, and had success with this in the 'Windows Device Manager' view, but it still had no effect on how it showed up in Cubase, and the same connection issue still happened.

I read one forum that said you can change the names of these in the midi utility on Mac, but I am on PC, and there doesn’t seem to be a way to change this. Ultimately, I think I want to be able to change how they appear in the ‘Port System Name’ column in Cubase, or find some other way for my computer to recognize these devices and completely separate things with unique names.

Thanks in advance legends!

Hi

Same thing happened to me, it used to work so I am wondering if an update killed it. i am trying to remember when it worked and I think it worked in the original 10.5

by 10.5.20 it didn't no matter what i did. i thought it was the unit but like you i hear it click

it def worked in all of the 10 ones

i have 11 now an it still doesn't work so i actually took it out

Use the LAN (RJ45) for connecting the third/four Xtender

Did you find a solution to this? I've been trying to set-up a pair of Icon Platform M+ units and have found the same issue.

I did have it showing up properly, but, I think a windows update may have changed that behaviour.

not yet, i am moving the studio right now and am on a new Imac but i will try it again when i set it back up later this week and report in
