I have VBUS sensing enabled and when I step through the call to HAL_PWREx_EnableUSBVoltageDetector(), you'd expect a difference in the bit states in the OTG_HS_GCCFG register but there is no difference whether the cable is plugged in or not.I find it...
I wanted to implement a simple USB device only on a STM32F407. When I enable it in CubeMX under USB_OTG_FS I get a DP and DM line and there is an option to activate the VBUS line. Is activate VBUS absolutely necessary? It is after a simple device onl...

I came across this Ethernet example:https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-workingIt is giving me an issue regarding configuring HSE in bypass mode. The maximum core frequency l can get is 96...
This thread is a new problem discovered while investigating a different USB-PD issue in another thread. @Yohann M. recommended that I create a new thread for this issue. Here is the link to the other thread: https://community.st.com/s/feed/0D53W0000...
Hi,I developing on stm32F4 and I having a problem with a USB Key Mass Storage Device.I using the MX library host usb as is, stand alone without other procedures.If I plug the usb key AFTER power on all is OK.If I power on with the usb key plugged in...
Hello,I have a very weird issue and I am looking for ideas on how to root cause it.My goal is to maximize the USB transfer speed in CDC mode.I started with the NUCLEO-L053I created a project with STM32CUBEIDE and added the USB CDC middleware.This res...
First when we connect our STEVAL-IDP004V1 to the 28V DC supply the LEDs Grouped together near to RS-485 connector not blinked even at startup and remains off. The Second when we connect STEVAL-IDP004V1 to the STEVAL-IDP005V1 and connect the master bo...
Hello,I'm developing firmware for STM32H750VB that uses the USB PHY to send MIDI over USB. I'm using the TinyUSB library for the USB stack. Right now I'm having trouble initializing the USB PHY due to it getting stuck in an infinite loop because it's...
