as to USB.

hi, what i'm trying to do is to interface two tm4c123gh6pm launch pads through USB. one would act as a host and the other would act as device. my goal is to enable the host launch pad to read data from and write data into device (launchpad). previously i have not worked on this peripheral, so i'm new to this USB. i went through the tiva ware USB library data sheet, the idea i found out is to configure the host launchpad as a host mass storage and configure the device launchpad as a mass storage  device. then interfacing both. but i'm unclear with how the enumeration would take place between them.  would this be feasible. if yes please help with sample stacks or programs. if not suggest me, how i can go about it.
