Everything works as well as possible via Thunderbolt4.

But I still haven't been able to get the OCuLink port to work. When I connect a powered-off laptop to the dock, the graphics card doesn't initialize. And if I turn the laptop on after that, everything freezes on a black screen; I can't even access the BIOS.

I used a GPD Win MAX 2 2024 with an OCuLink port before, and I had no problems with it.

I suspect the problem is with the AOOSTAR dock, as it uses an ASMedia controller. The only working build with a similar laptop was the Minisforum DEG2, which uses an Intel controller.

I'd be very grateful if anyone could help me.
