Arduino nano 33 ble with a Nina-B406 instead of a Nina-B306

Hello,
I made a project where i redrew the existing Arduino nano 33 ble shematic where I also made a bigger board design.

When I transplant the Nina-b306 chip from the arduino nano 33 ble onto my own board design everything works fine. So then I replace the Nina-b306 on my board with the Nina-b406 chip (the b406 is not pre-flashed with a bootloader) and flash it with the bootloader of the Arduino nano 33 BLE (following this guide: Burn bootloader Arduino nano 33 BLE | Djynet). And I succesfully bootload the board. The green led goes on instead of the orange one so this is a good thing. But windows doens't recognize this device, I get a "Unkown USB Device (Device Descriptor Request Failed).

So there is something wrong with the software, I can't really find any info on a different bootloader for the Nina-b406. So I was wondering what I must do to get the board working using a Nina-b406 instead of a Nina-b306. And the problem will be in the firmware/bootloader.
So I guess I must change something on the source code of the bootloader, but can't find this anywhere.

(I've already tried pressing the reset button 2 times, but doesn't change anything)

Hello, did you make progress on it ? I would also love to replace the Nina-306 by Nina-406

Did you try to put the Nina-406 on the Arduino nano33 ?

No, nothing....

yes, and it won't work, the computer won't detect the nina b-406 correctly with the bootloader of the b-306

I have raised the issue to UBlox forum, let's see what they answer https://portal.u-blox.com/s/question/0D52p0000D5etvFCQQ/how-to-replace-an-nina306-by-a-nina406-on-a-board-based-on-arduino-nano-ble
