STM32F407 USB Host config

SohamC · ‎2025-09-22

Hello ,
I am currently trying to configure STM32F407 board as USB host. The code for it is given below. I am not receiving anything from the USB device(bus powered). I have a doubt that it might be related to the hardware of it(VBUS). The rest of the code is generated by the IDE itself so there is no doubt related to it. I have configured it as USB host only mode. I am new to embedded systems so any kind of help would be appreciated. Is there anything wrong with the code or any links to help me configure the USB host.
I would be glad to clarify any queries related to the above.

In particular, what STM32F407 board are you using, and what is the USB device?
