How to Read/Write few Bytes of data from a Microcontroller using USB ?

[firoz3321]

Hi,

I am new to USB.
My basic requirement is that the microcontroller (TI LM4F232H5QD) has few bytes of data (13 bytes as of now).
the outside world should be able to read those Bytes when ever it needs.

Say, The outside world (Master) requests data, then the controller will fetch the data and return to the Master.

I implemented the same functionality using UART, I2C and ModBus so far. But how do i do it using USB ?

I am confused between so many classes in the USB.

A little guidance will help me a lot.

Thanks in advance.
