Setup:
Windows 10
STM32Cube_FW_F4_V1.27.1 - latest
CubeIDE V1.11.0 - latest
Azure RTOS - F4 - V1.1.0 - latest
USBX V6.1.10 - latest
STM32F469I-Discovery MB1189 - B03
Ux_Host_HID_CDC_ACM - Example from repository - latest
I want to connect an STM32F469I-Discovery board as USB host to different CDC_ACM devices equipped with the popular FT232 / CP210x / CH340 USB to serial bridge chips.
None of these chips will be recognised by the USBX host in the example project.
Strange enough, a Raspberry Pi-Pico board works well including data transfer in the same setup. Arduino Mega 2560 too - kind of.
I'm aware that these chips might have some non standard descriptors.
Any idea how to get this working?
Thanks and regards
