Hello everyone.
I configured stm32H733VGT6 to support the usb2514 hub device. To do this I used Azure RTOS and the USBX library with STM32CubeIDE Version: 1.17.0. Everything works fine, the USB2514 device is always recognized at power-on with the correct VID and PID (see the image). The problem is that when I connect a device to one of the 4 usb ports (downstream), insertion is recognized (UX_DEVICE_CONNECTION event), as well as removal (UX_DEVICE_DISCONNECTION event), but the peripheral is not recognized.
The USB2514 is configured with SEL0, SEL1, NON_REM0 and NON_REM1 all with pulldown resistors (100KOhm) to GND.
The strange thing is that at startup, even if there are no devices connected to the USB downstream ports, the event UX_DEVICE_CONNECTION occurs.
When I connected a device, the condition:
if (current_class -> ux_host_class_entry_function == ux_host_class_cdc_acm_entry)
current_class returns a wrong ux_host_class_name and exit from if statement, always.
Is there anyone who has encountered this problem and solved it?
Thank you, Paolo.
