Hello, friends!
I have new build with I9 13900K Processor and Asus Hero Motherboard. The MB has 2 built in Thunderbolt 4 ports. ROG MAXIMUS Z790 HERO | ROG MAXIMUS Z790 HERO | Gaming Motherboards|ROG - Republic of Gamers|ROG USA (asus.com)
I have project recording studio and use MOTU Thunderbolt audio interface. MOTU.com - Overview
It is relatively expansive gear around $1500 per unit and I have 3 units, so it is not easy to replace. The interface is using Thunderbolt 2.0. My previous build Kaby Lake, 2017, I also had Asus Hero motherboard with Thunderbolt 3.0 and was using Apple TB 3.2 to 2.0 adopter.
From my research, TB 4.0 should be back compatible with TB 3.0, therefor, in theory, my interfaces should simply connect to the new system with the same Apple adopter. But they not recognized.
I contacted MOTU. You would think- by now, they would know if their flagship product is compatible with TB4 and would know how to troubleshoot it as they still offering this interface. This is reply I got from their tech support:
Thanks for contacting MOTU. In order for this to work, we first have to check if the Thunderbolt 4 port actually works in your computer. Since your computer is a custom-built one, we might have to make sure that a number of things are true in your computer:

To make Thunderbolt 2 interfaces work with Thunderbolt 4, one must use a Thunderbolt 3 to Thunderbolt 2 adapter. We recommend the following.
In our tests we used the following externally powered devices with the TB3 / TB2 Adapter on the downstream port:

Thanks for contacting MOTU. In order for this to work, we first have to check if the Thunderbolt 4 port actually works in your computer. Since your computer is a custom-built one, we might have to make sure that a number of things are true in your computer:
-
- Is every component of your recently built computer compatible with TB 4? This is needed for TB 4 to work.
- Are all the TB-related software installed and updated for your Intel processor?
- Is the motherboard confirmed to provide backwards compatibility between TB 3 and TB 4? Some motherboards have been found to skip the backwards compatibility feature.
- Not sure what components of computer would not be compatible. The processor? Obviously the memory would not care. Yes, I gave them specs- I have I9 13900K, it supports TB.
- I just reinstalled the TB driver just in case I didn't install it with all the drivers earlier, so it is installed.
- How would I check if Hero MB provides back compatibility?

To make Thunderbolt 2 interfaces work with Thunderbolt 4, one must use a Thunderbolt 3 to Thunderbolt 2 adapter. We recommend the following.
- Startech TBT3TBTADAP - Thunderbolt 3 to Thunderbolt 2 Adapter
- Apple Thunderbolt 3 to Thunderbolt 2 Adapter (not compatible with Dell products)
- Akitio Thunderbolt 3 to Thunderbolt 2 Adapter
In our tests we used the following externally powered devices with the TB3 / TB2 Adapter on the downstream port:
- Cal Digit Thunderbolt 4 Hub
- Dell K16A Dock
- Lacie D2 HDD with 2x TB3 Ports.
