Usb host controller shield

Hello not sure if it his is a storage, hardware or programming Question but i have a question Is it possible to make the usb host shield into a hid drvice? i know you can put stuff from the arduino to the usb flash drive but what about interfacing with a pc? What i mean is i alwas don't want to unplug my flash drive from my arduino so is there a way i can access it to the pc so i don not have to unplug it?
