Strangely, it only works if I activate both ports (then disable one, if you are not going to use both).
I'm trying to create a project with RTOS, I've tried everything I've found on the internet, but it still hasn't worked.
I already have a project working with two USB ports in Host mode, the HS port in MSC mode and the FS port in HID mode.
I have two identical bords with STM32F407VG, and the same symptom occurs on both.
I have a pendrive with built-in LED indicator, to facilitate access monitoring.
When creating a project without RTOS, I noticed that the flash drive's LED did not blink. The USB debug messages were also not displayed.
This is true for both FS and HS ports.
Using STM32CubeIDE 1.4.2 and package STM32Cube_FW_F4_V1.25.1
Please check.
