Code:

#include "CCSUSB.h"

#include <pic18_usb.h>
#include <usb_desc_hid.h>
#include <usb.c>

void main(void){
   unsigned int8 delay = 0;
   unsigned int8 out[2];
   unsigned int8 in[2];
   
   LED_OFF(GREEN_LED);
   LED_OFF(YELLOW_LED);
   LED_OFF(RED_LED);
   
   setup_adc(ADC_CLOCK_INTERNAL | ADC_TAD_MUL_2);

   set_adc_channel(AN_POT);
   
   usb_init_cs();
   
   while(TRUE) {
      usb_task();
      if(usb_enumerated()) {
         LED_ON(GREEN_LED);
         
         delay++;
         if(delay>=250) {
            delay = 0;
            out[0] = read_adc();
            out[1] = BUTTON_PRESSED();
            usb_put_packet(1,out,2,USB_DTS_TOGGLE);
         }
         
         if(usb_kbhit(1)) {
            usb_get_packet(1,in,2);
            if(in[0]){LED_ON(YELLOW_LED);} else {LED_OFF(YELLOW_LED);}
            if(in[1]){LED_ON(RED_LED);} else {LED_OFF(RED_LED);}
         }
         
         delay_ms(1);

The description of the parameters for the usb_put_packet() function
is given in the usb_hw_layer.h file. It comes with the CCS compiler
and it's in the following directory on your computer:
Quote:
c:\program files\picc\drivers\usb_hw_layer.h

The function description will tell you exactly what you need.
