Allow "Configuration Descriptor" choice with UsbX Host

[piovemas]

Hi,
I'm using UsbX Host with STM32H563 microcontroller. I need to use USB to Ethernet USB device like "ASIX Electronics Corp." AX88179 Gigabit Ethernet. It supports CDC-ECM class.
I discovered that this USB device have got 3 "Configuration Descriptor". UsbX manage only the first "Configuration Descriptor".
So my suggestion is to add a function to select which "Configuration Descriptor" to use.
Also linux (Ubuntu for example) allows to select the "Configuration Descriptor" to force to use a particular driver.
Thanks
