Hi,

Have you considered using a newer Linux BSP? On each version many bugfixes are added (recently, USB patches were applied); so, it is recommended checking L4.1.15 BSP release.

Regarding a hardware side, you could try grounding the ID pin to switch to Host mode; otherwise, the module will remain as Device.

Hope this will be useful for you.
Best regards!
