USB device enumeration query

[mahesh mv]

Hi all,
We have  a board where we plan to connect 2 USB devices of MASS storage class. One of the devices (3) is plugged in all the timebut the other USB is hotplugged when ever its required. The issue we are facing is the device number is not deterministic acrossreboots with uboot 2021 . Is there a way to fix the Device 3 below as the first one all the time in DTS file or some other mechanism in uboot.
