It's required for `usb_gadget_initialize` to provide a "USB
controller index" as an argument.
Hi!
As I can see, recently [1] the implementation of USB ACM gadget has
been merged into U-boot master. I tried to use it but the problem is
that running `setenv stdout usbacm` on my board based on STM32MP157
leads to errors below:
STM32MP> setenv stdout usbacm
couldn't find an available UDC
