Hello @Bench​ ,

You are right, I confirm that using STM32CubeMx (version 4.27.0), the MspInit functions are empty and there is no GPIO Configuration for STM32F303 and STM32F302.

This issue is raised internally to CubeMx team for fix.

Thank you for bringing this issue to our attention.

Kind Regards,

Imen.

I have no Android device with USB host, but I use Linux computers daily. I tried the CDC code from Cube HAL a few days ago and it worked out of the box. So you may retry with the current Cube HAL release.

I also developed an independent driver that you may try: https://translate.google.com/translate?hl=en&sl=de&tl=en&u=http%3A%2F%2Fstefanfrings.de%2Fstm32%2Fstm32f3.html%23vcpnohal&sandbox=1

The code is very compact and straight forward, only two files (usb.c and usb.h).

The driver contains the company name "Nuvoton" because it was originally published by a member of that company. If you like to contact him, leave a message in https://www.embdev.net

It's impossible to find any f303ze USB resources. Struggling to even get it to receive setup packets. Initializing it with the HAL and it seems to only trigger the resume interrupt when plugged in. Then nothing. Wish there was actual documentation about how to use this thing
