In Reply to: Yes, there is now a USB 4 protocol standard posted by Feanor on December 9, 2023 at 04:50:18:
No.
Part of USB is what is called the device enumeration.
The DAC will tell its properties like supported bit dept and sample rate, etc.
If it is a UAC2 device, the speed of the bus will always be High Speed (480 Mhz).
Older DACs (UAC1) only works with Full Speed (12 Mhz).
It is the USB receiver of the DAC that determines the speed.
