#define VID_PID_TABLE

Value:

{VID_ATMEL, 2, PID_MegaHIDMouse, 0x2014 \
                                    ,0x0123, 3, 0x2000, 0x2100, 0x1258}
VID/PID supported table list This table contains the VID/PID that are supported by the reduced host application VID_PID_TABLE format definition: define VID_PID_TABLE {VID1, number_of_pid_for_this_VID1, PID11_value,..., PID1X_Value
...
,VIDz, number_of_pid_for_this_VIDz, PIDz1_value,..., PIDzX_Value}

#define CLASS_SUBCLASS_PROTOCOL

Value:

{\
                                       0x00, 0x00, 0x00,\
                                       0x00,0x55,0xAA}
CLASS/SUBCLASS_PROTOCOL supported table list This table contains the CLASS/SUBCLASS/PROTOCOL that is supported by the reduced host application This table definition allows to extended the reduced application device support to an entire Class/ /subclass/protocol instead of a simple VID/PID table list.

define CLASS_SUBCLASS_PROTOCOL {CLASS1, SUB_CLASS1,PROTOCOL1,
...
CLASSz, SUB_CLASSz,PROTOCOLz}
