USB_DEVICE no longer available? Only RTOS USBX for bare metal?

[Jack3]

Hello STM32 developers,

I/m using STM32CubeMX 6.14.1

I noticed that in middleware the selection "USB_DEVICE" has disappeared.
Instead, "USBX" is listed, however it is for RTOS, and I don't use RTOS, so I'm left with nothing.

I think the STMicroelectronics USB stack would still be available, somehow:

https://wiki.stmicroelectronics.cn/stm32mcu/index.php?title=USBX_overview&oldid=10172

Besides offering STMicroelectronics USB stack, USBX, the Azure RTOS USB embedded stack is currently supported and offered with a set of applications running on STM32 MCUs.

How can I use the STMicroelectronics USB stack > "USB_DEVICE" instead?

Do I need to install some software for it?

Hello @Jack3 

First let me thank you for posting.

I'm currently investigating this, I will get back to you asap.

Hi,

maybe , this is what you looking for :

Hi @Jack3 

STM32U5 is natively developed using USBX.

For products natively developed using USBX, CubeMX does not support ST's USB_DEVICE stack library.

However you can refer to examples without CubeMX supporting classic middleware : WBA ,U3, U0, N6 , C0 , U5 and  H5.
