USB to OTG port on MCIMX6Q-SDB

Why is the OTG/USB keyboard and mouse considered not supported on android_L5.0.0_1.0.0 and related kernel builds on the MCIMX6Q-SDB? The board has the OTG port.  Using a 6 inch micro B male to USB A female OTG cable to the OTG port and either connecting a 3.0 USB HUB or keyboard directly into the USB A.

 

Similar bug was found and the suggested fix was to deselect USB_OTG_FSM. 

 

Is this the correct solution and why on freescales L5.0.0_1.0.0-ga_core_image_6qsabresd pre-built image? 

 

If OTG_FSM is deselected, will the USB-OTG cable function as a USB straight through cable without the USB 2.0 USB_OTG_FSM support?
