Terminate USB host mode on TC75?



We are developing an HW add-on device for the TC75/TC70 with a Silabs CP201x USB-to-serial chip in it.

We would like to be able to switch the USB port mode from inside our Android application.

We want to switch the USB power supply from the TC75 to the add-on device to prevent draining the TC75 battery when the add-on device is not used.


So my question is: Is there a way to terminate USB host mode by EMDK API?
