Hi, Want to know if a STM32H7A3Z1-Q can configure as USB OTG Host ? We tired the configuration as per online tutorials and the device is not entering into HOST_USER_CLASS_ACTIVE state.

[JJoy.1]

The other end of USB is a custom board which can act as a CDC device.

(When connecting the custom board to PC, interface showing as per the attachment.. Showing as RNDIS interface and 3 virtual COM Port.)

Attached code which we tried for USB host. Please let us know, is there any change in configuration needed or any additional code changes required..

It would be great if you can give an insight into the issue.

Thanks in advance.
