Portenta H7 using 4.1.0-rc2 loses USB after updating firmware

[mjs513]

Describe the bug
Portenta H7 compiles and loads seemly after updating firmware but USB is lost after upload and lost at firmware upload. However Sketch (BLINK) still runs!!!

Target board + cli verbose compilation output

Some possible background information. @mjs513 and I have been trying to figure out what is different. Between the GIGA and the Portenta H7 and what changed between the stuff up till the zephyr 4.1.

We know that the GIGA uses USB_FS for communications to the pc, where the Portenta uses USB_HS object for the communications.
One thing we have noticed is that with the 4.1 build, the Portenta now has two CDC_ACM objects in the tree, where as earlier it only had one, and likewise the GIGA only has one in both the older and newer configurations. Here is a snippit of the dtsh output
showing the two: tree --format NKYC > /mnt/d/temp/dtsh_H7_v4.1.html

I included the giga and H7 dtsh outputs here in case anyone wants to take a look

dtsh_html_outputs.zip

Now trying to figure out whare the 2nd one (board_cdc_acm_uart) came from and if it matters.

@facchinm @pillo79 @mjs513 - I believe I have a fix for the USB issue here.
As I showed in the posting two days ago. The Portenta H7 added a new object to the usb@40040000 object, the
board_cdc_acm_uart.

I found that object was defined in zephyr: <../boards/common/usb/cdc_acm_serial.dtsi

I looked for who included this file and found that only two of the Arduino boards included it:

~/github/zephyr/boards/adafruit/itsybitsy/adafruit_itsybitsy_nrf52840.dts:
  153  };
  154  
  155: #include <../boards/common/usb/cdc_acm_serial.dtsi>
  156  

~/github/zephyr/boards/arduino/opta/arduino_opta_stm32h747xx_m7.dts:
   29  };
   30  
   31: #include <../boards/common/usb/cdc_acm_serial.dtsi>
   32  
   33  &clk_hse {

~/github/zephyr/boards/arduino/portenta_h7/arduino_portenta_h7_stm32h747xx_m7.dts:
    9  #include <st/h7/stm32h747xihx-pinctrl.dtsi>
   10  #include "arduino_portenta_h7-common.dtsi"
   11: #include <../boards/common/usb/cdc_acm_serial.dtsi>
   12  
   13  / {

~/github/zephyr/boards/atmarktechno/degu_evk/degu_evk.dts:
  174  };

I also noted that the GIGA had added another chosen define that was in that looked related, so I added it as well
to the H7s in the overlay, like:

    chosen {
        zephyr,console = &usart6;
        zephyr,shell-uart = &usart6;
        zephyr,cdc-acm-uart0 = &usart6;
        zephyr,uart-mcumgr = &usart6;
    };

(The uart-mcumgr) line.

I removed it from the Portenta H7 board and rebuilt and reflashed and programmed and now have USB working again on the H7

Edit: @mjs513 confirmed the zephyr,uart-mcumgr = &usart6;
was needed.

[mjs513]

@KurtE - @facchinm - @pillo79

Just verified that the fix does work using zephyr 16.8. Just one note

Have to add zephyr,uart-mcumgr = &usart6; otherwise nothing is printed to Serial monitor.

[mjs513]

Just started doing some regression testing on the nano, giga and H7. So just tested this on the H7 and release of 0.3.0 fix the issue.
