I have an Adafruit STM32F405 Feather Express. I am compiling / uploading with Arduino IDE V2.1.0 with Windows 11 64. The board worked well for about a week, but no longer connects/shows up as Port 5 of USB. I was successfully connecting and uploading code with the Arduino IDE. After a few days away from the project, I discovered my STM32F405 Express no longer connects to the USB. I did attempt to install MS WDAC - see below.
When I jump B0 to +3.3 and press reset, (I hear a USB connect sound) under "Universal Serial Bus devices", "STM BOOTLOADER" appears in the device manager; it's always visible w/ or w/o the 405 if "View -> Show hidden devices" is checked). Unplugging the USB after a BO+reset generates a "disconnect" sound. Nothing appears under "Ports (COM & LPT)". When it was working, I could see it under "Port 5". Now, neither the STM32, nor any other device, is visible on the IDE under "Tools -> Port".
With the device manager and looking the STM BOOTLOADER Device Manager properties / Events tab / "Device install requested", I see "Device USB\VID_0483&PID_DF11\2065326F4D31 requires further installation." A B0+reset generates a "connect" sound, but no sound is generated otherwise.
The code I previously uploaded which simply sets up two PWM channels appears to be working - I can see waveforms on the 6 and 9.
If I connect a Nano to the USB, "USB-SERIAL CH340 (COM6)" appears and the Arduino IDE sees it as "COM6".
After seeing a caution icon on the "Windows Security - Actions recommended" icon in the task bar, I did attempt, apparently unsuccessfully, to install the Microsoft Windows Defender Application Control about the time the problem occurred. MS WDAC.
I did uninstall/reinstall Arduino IDE 2.1.0 The problem still exists. Same content in the Device Manager. Uninstalled/reinstalled "STM32 MCU based boards by STMMicroelectronics" 2.5.0 Per the instructions on Arduino IDE Setup setup page, "STM32 Cores by STMicroelectronics" no longer appears to exist, used a new version.
Any suggestions or hints would be appreciated.
Thanks -Jim
