Missing dependencies: DT_HAS_ZEPHYR_CDC_ACM_UART_ENABLED

[Thibaud]

Hello,

I am developping a product with a composite USB device : HID and CDC_ACM classes . 

My problem today is, when I start developping from an hello word project, I can't enable USB CDC ACM Class Support in the kconfig.

When I try to add manualy the ligne : CONFIG_USB_CDC_ACM=y, in the file prj.conf a warning appears saying : Missing dependencies: DT_HAS_ZEPHYR_CDC_ACM_UART_ENABLED

I already looked at every cdc_acm example and like the examples I created a .overlay file to add the node in the devicetree. 

I checked in the devicetree and the cdc_acm_uart0 node is present, I checked the depencies in kconfig and all the necessaries ones are enable. 

Do you know what did I missed to enable the cdc acm class support ? 

Thanks

Hello,

I am using SDK version 2.2.0 and nRF52833_dk.

The problem just magically disappeared when i logged in this morning, but do you have any idea of what is DT_HAS_ZEPHYR_CDC_ACM_UART_ENABLED ? 

I still can share you my project if you want to look at this issue for the future.

Not sure about the error. Might be because of something missing in the DTS or device is not enabled properly.
