I have been running sketches for using the USB host and I have found a structure which I cannot find in the header files.
The structure is EP_RECORD and it is being called in the sketch for the keyboard. The sketches have been taken from the Oleg from the below mentioned link

Can anybody tell me where this structure and its function have been defined. Is it a default structure ?
BR,
