How can I use the USB CDC in standalone mode on the STM32U0 series?

I'm developing an application using the STM32U073RBT6. CubeMX configures USBX - CDC ACM based on Azure RTOS.

How can I use the USB CDC stack of the STM32U0 series in standalone (bare-metal) mode?

(or Is it possible to migrate the libraries from the previous L0 series?)

Hi @pyoruya

Currently, STM32U0 do not support Classic core Middleware, only USBX is supported STM32CubeU0/Projects/STM32U083C-DK/Applications/USBX/Ux_Device_CDC_ACM at main · STMicroelectronics/STM32CubeU0 · GitHub.

Thank you for your response.

Does this mean that the following library cannot be used with the STM32U0 series? https://github.com/STMicroelectronics/stm32_mw_usb_device

Is modifying the USBX CDC ACM to a bare-metal (standalone) form the best approach in this case?

Thank you for your assistance.

@pyoruya I cannot assume it cannot be used for U0 series. But for testing purposes, I assume, getting inspired by USBX stack would be the best approach for testing purposes.
