my code is:
led is blinking. (4 sec)
but usb 1 times enumerated. Last led blink usb is not enumerated.
compiler version 4.119
thanks.

#include <18F14K50.h>

#use delay(clock=12000000)
#define USB_CONFIG_HID_TX_SIZE 8
#define USB_CONFIG_HID_RX_SIZE 8
#include <pic18_usb.h>
#include <usb_log_hid.h>
#include <usb.c>
#define led1 PIN_C3
#define usb_sense PIN_C1
int8 ticks=0;
int8 usbstate=0;
int8 x;
int8 in_data[8];

{
}
void usb_debug_task(void)
{
int8 new_connected;
int8 new_enumerated;
new_connected=usb_attached();
new_enumerated=usb_enumerated();
if (new_enumerated) output_high(led1);
else output_low(led1);
}
void main(void)
{
setup_timer_1(T1_EXTERNAL| T1_DIV_BY_1 | T1_CLK_OUT);
set_timer1(0);
enable_interrupts(INT_TIMER1);
usb_init_cs();
in_data[0]=0;
while (TRUE)
{
ticks=0;
output_high(pin_c3);
delay_ms(50);
output_low(pin_c3);
if(input(usb_sense)) usbstate=1;

case 1: usb_task();

if (usb_enumerated())
{
if (usb_kbhit(1))
{
usb_get_packet(1, in_data, 8);
x= in_data[0];
}
}
break;
case 0:do { sleep();
delay_cycles(1); //Instruction pre-fetched - NOP
clear_interrupt(INT_TIMER1);
} while(++ticks<2); //4
break;

Use the drivers....
| Code: |
#include <18F14K50.h>
#fuses HS,NOWDT,NOLVP,NODEBUG,CPUDIV4,NOMCLR,NOPUT,NOBROWNOUT,USBDIV1
#use delay(clock=12000000)
#define USB_CONFIG_HID_TX_SIZE 8
#define USB_CONFIG_HID_RX_SIZE 8
#define USB_CON_SENSE_PIN PIN_C1 //Must be done before USB.C
#include <pic18_usb.h>
#include <usb_log_hid.h>
#include <usb.c>
#define led1 PIN_C3
int8 ticks=0;
int8 x;
int8 in_data[8];
#int_TIMER1
void timer1_isr(void) {
}
void usb_debug_task(void) {
int8 new_connected;
int8 new_enumerated;
new_connected=usb_attached();
new_enumerated=usb_enumerated();
if (new_enumerated)
output_high(led1);
else
output_low(led1);
}
void main(void) {
setup_timer_1(T1_EXTERNAL| T1_DIV_BY_1 | T1_CLK_OUT);
set_timer1(0);
enable_interrupts(INT_TIMER1);
usb_init_cs();
in_data[0]=0;
while (TRUE) {
ticks=0;
output_high(pin_c3);
delay_ms(50);
output_low(pin_c3);
switch(USB_CABLE_IS_ATTACHED()) {
case TRUE:
usb_task();
usb_debug_task();
if (usb_enumerated()) {
if (usb_kbhit(1)) {
usb_get_packet(1, in_data, 8);
x= in_data[0];
}
}
break;
case FALSE:
do {
sleep();
delay_cycles(1); //Instruction pre-fetched - NOP
clear_interrupt(INT_TIMER1);
} while(++ticks<2); //4
break;
}// switch
}//while
}//main

Using usb_init_cs, _requires_ 'USB_CABLE_IS_ATTACHED' to be available as a macro, saying if the cable it present. It'll be defined for you automatically, if you define 'USB_CON_SENSE_PIN', but this needs to be done before you load usb.c. You have called the pin 'usb_sense' instead, and done it after loading usb.c, so the connection sense ability in the functions is basically turned off....

| Code: |
#if defined(USB_CON_SENSE_PIN)
// #undef USB_CABLE_IS_ATTACHED
#define USB_CABLE_IS_ATTACHED() input(USB_CON_SENSE_PIN)
#endif

usb.c file will be like this? |

I did correction. But if the LED blinking coincides usb is working.
Also this correction file usb.h
mine connection
.....................4k7
VBUS-----+----/\/\/\/\/\----- (I/O PIN ON PIC)
...............|
...............+---/\/\/\/\/\-----GND
................... 100k
actually connection
.....................100K
VBUS-----+----/\/\/\/\/\----- (I/O PIN ON PIC)
...............|
...............+---/\/\/\/\/\-----GND
................... 100k |
