Detecting Pen Drive Insertion on LPC1768

[Prakash]

Hello

I am using LPC1768 for one of the project and i need to detect if the USB device is plugged in. How is it possible that i detect something like a pen drive being inserted.

I will be using the controller to interact to the PC as well as with a pendrive and i dont intend to use OTG. I need to have a option which will be able to detect the connection type.

Regards
