Does anyone know how many individual thunderbolt 4 and USB 3 controllers are in here.
I’m trying to determine the maxim attachment limits.

For those who wonder I can now confirm a few things.
+

At least for the ultra. Let’s first mention that the M series chips, like apples later A chips, DO have USB controllers. It’s a logical, or soft controller implementation in the chip’s ISC but it’s still there.
+

Based on power draw testing the thunderbolt ports are individually powered. I don’t have 127 devices to test my theory, but I believe each port is solo control.

Second, the two usb A ports are shared; a single controller.
