The same USB hub and connected devices do not present any issues when used on a Nexus 7 tablet or a Freescale i. These two are related for sure clock dependencies but what I am not sure about is if they also relate to separate controllers an EHCI host controller and an OTG controller or a single controller which uses both the drivers. Although this sounds like the end of the road in relation to these issues, I am not understanding one fundamental concept with this controller and perhaps you have some useful insights.

Although this sounds like the end of the road in relation to these issues, I am not understanding one fundamental concept with this controller and perhaps you have some useful insights. The code is filled with bugs and the old code is really slow.
