A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Hello @oysteikr 
As @Andrew Neil said and Based on the datasheet.

OTG_HS_DM is located at the PM5 pin, and OTG_HS_DP is located at the PM6 pin.
