Hi
I want to make a composite device in the USB-3 of G420 platform with Yocto.
The composite device including the UVC, UAC, HID-1, HID-2, HID-3, HID-4, ADB, and MSD.
The UVC needs support the 4K@30.
The UAC only speaker output feature.
From below ticket, there are 15tx/15rx in the USB-3 port-0 of G520/G720. It is enough for composite device requirement.

If I connected the USB-3 on my computer, it should work.
But if my computer only has USB-2, will the number of TX/RX still be enough? And can the device still be used normally?
In addition, what is the SRAM of USB-3? And if it is downgraded to USB-2, will SRAM still be the same?
