I try to force USB OTG port to host and modify registry as following.
HKLM\Drivers\BuiltIn\USBOTG
626-2017-11-07-21-06-02-colibri.png

Meanwhile keeping SOIDMM137/135 unconnected.

A mouse is connect to iMX7S via OTG2USB cable, but it is not detected and cursor is missing.

Is there any key I miss in registry ?
Thanks very much！
