    Hi Tsuneo,

    By your instruction I already modify my source code.
    Please see modify function below.

    usbuser.c

    void USB_Configure_Event (void) {
  int i;
  if (USB_Configuration)
  {                  /* Check if USB is configured */
        for (i=0; i<8; i++)
                KeyReport[i] = 0;
    USB_WriteEP(0x81, KeyReport, sizeof(KeyReport));
  }
}

void USB_EndPoint1 (DWORD event) {
  int i;
  if (KeyPress)
        saystr ("USB_ENDPoint1\n\r");
  switch (event) {
    case USB_EVT_IN :
          KeyScan ();
      USB_WriteEP(0x81, KeyReport, sizeof(KeyReport));
      if (KeyPress) // for debug on console
          {
            for (i=0; i<8; i++)
                {
                  sayhex (KeyReport[i]);
                  saystr (" ");
                }
                saystr ("\n\r");
                KeyPress = FALSE;
          }
          break;
  }
}

    Output on hyperterminal is :

    USB_ENDPoint1
    00 00 04 00 00 00 00 00

    but notthing put on notepad. So my test solution is correct or not?

    and KeyScan function is :

    void KeyScan (void)
{
  switch (Key)
  {
         case 'a' :
           KeyReport[2] = 4;
           break;
         case '1' :
           KeyReport[2] = 30;
           break;
  }

}


    Key is gobal variable when I push button.

    and I wonder about GetInReport (), I set KeyPress = TRUE when I push button.

    void GetInReport (void)
{
  InReport = 0x00;      /* Default All Input */

  if (KeyPress == TRUE)
  {
    InReport = 0x01;
  }
  else
  {
    InReport = 0x00;
  }
}

    Thanks you,
