I just received the “Seeed Studio XIAO nRF52840” (the basic one, not the sense). First, I wanted to use it with arduino ide (1.8.18). Adafruit nrf52 boards were installed for a couple of years. So, I just added the url for seeed boards. When I tried to compile Blink, I faced the USBD issue. I removed the url for seeed boards and, later, all seed folders that I can find. I downloaded your patch and copied the content to the corresponding arduino folder. Now, I’m facing the missing nrf_soc.h file issue.
Arduino : 1.8.18 (Windows 10), Carte : "Seeed XIAO nRF52840, S140 7.3.0, Level 0 (Release)"

Indeed, the nrf_soc.h file was provided by the patch and is available in :
C:\Users\MyName\AppData\Local\Arduino15\packages\adafruit\hardware\nrf52\1.4.0\softdevice\s140_nrf52_7.3.0_API\include
(And also in C:\Users\MyName\AppData\Local\Arduino15\packages\adafruit\hardware\nrf52\1.4.0\cores\nRF5\nordic\softdevice\s140_nrf52_6.1.1_API\include and C:\Users\MyName\AppData\Local\Arduino15\packages\adafruit\hardware\nrf52\1.4.0\cores\nRF5\nordic\softdevice\s132_nrf52_6.1.1_API\include
So, what?
