USB hub recommendation for guitar rig

Hi -

I am trying to find a hub that allows me to have one cord going from my pedalboard to my iPad Pro (2025 version). It should host:

Scarlett 4i4
Hx stomp
Morningstar mc6 pro
Arturia minilab 3
Have room for 3 more midi controllers.

I know this has been discussed only a bajillion times on this sub but I’m really struggling to find a solution. Here are some usb hubs I’ve tried.

https://a.co/d/0bdc3u2a

I’m open having the hub plug into the camera adapter, with an extender that sends the single usb cable to the iPad. I tried this extender with the above and nothing has worked yet.

Has anyone found a good solution that could work? Thank you all!

    iPadOS / iOS only allows one active audio input device at a time. You can have multiple midi controllers active but only one audio device. No hub can get you around that limitation.

    Also, I'd be wary of using a USB-C "extender" cable to connect the camera adapter to the iPad. The camera adapter is designed as a dongle, and it may not have enough oomph to push signals that far (cable capacitance/resistance). Your best choice will be powered USB-C hub with power delivery, and a long connection cable. There are some hubs that have a removable cable.

    Gotcha understood- to be clear I’m only using the Scarlett as the interface.

    Got it that’s helpful. Are you able to comment on the usb hub links I’ve shared? They are delivering data but not power, wondering why since they said PD on the description.

    Chat GPT said that I could change the battery protection settings on my iPad (it’s the newest version) but I’m nervous to do that.

    I don't know the particulars of any of those hubs, but I would think it wise "in this day and age" to pick the one that has both USB-A and USB-C ports. Just a random 2-cents

    Of the three you showed, the first and last are "conventional" USB powered hubs, so they know nothing about USB-C PD. They may have 5V power ports that can work with the old Lightning camera adapter. The middle one is USB-C, but it sounds like their "PD" ports are for charging only, not the host data connection. This is a bit strange, but if you've tried it, you would know. That is correct terminology though; my multiport wall adapter marks its USB-C ports as PD. You may need to search further. I know it's difficult to find simple USB-only USB-C hubs without the dock bells and whistles.

    Chat GPT said that I could change the battery protection settings on my iPad (it’s the newest version) but I’m nervous to do that.

    I believe the only meaningful battery setting is the 80% charge limit option, but that has no effect on PD working or not.

    I think that’s the trick - I’ll just have to accept something with hdmi and SIM card against my ocd tendencies
