TM4C1294NCPDT: USB - VBUS pin connection Queries

Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: TPS2052B

We are using TM4C1294NCPDTI3 in our design. We have a query regarding VBUS connection.

Our application is to connect USB pen Drive to the port (Host). We need to detect connection/removal of USB pendrives.

1. What to do with VBUS pin on the TM4C1294NCPDTI3?
a) Do we need to connect it to USB connector?
b) Does VBUS pin in TM4C1294NCPDTI3 provide 5V and current for powering USB pendrive?
c) We are using power switch for protection of External USB problems, For that can we connect VBUS of TM4C1294NCPDTI3 as input to Power switch IC?
