Please bring back old USB middleware

[bleqy]

Hello, STM employees,

I have bought the NUCLEO-N657X0 board with the intentions of using its USB on the go module. I have previous experience with USB with STM32f401, where I had to employ a single function CDC_Transmit(), and STM32CubeIde and Hal did the rest. It was simple and easy to implement. Currently Im struggling with doing the same with the N6 MCU, but proved impossible. I've tried all tutorials found on your site and community available ones, but could not find a single example that would send "Hello World!" to my PC. I'm sure my board works as I've run a basic blink sketch from the external ROM.

Please, if you could add the same middleware for f401 to n657, that would be great.

hello @bleqy 
I am sorry to hear about your struggles.
Did you try to run our firmware examples?
Here is a CDC_ACM firmware example. You just need to compile and run it.
You can exploit it to better understand how the USBX middleware works.

Hope that helps.

About classic ST library I would add and recommend the following example from the classic core MW repository.
