Objective Development Forums

I have two questions.

1 > I am using Metaboard and have uploaded the V-USB code to it for HID keyboard.I have pasted the code below:

#include "UsbKeyboard.h"

#define BUTTON_PIN 12

// If the timer isr is corrected
// to not take so long change this to 0.
#define BYPASS_TIMER_ISR 1

void setup() {
pinMode(BUTTON_PIN, INPUT);
digitalWrite(BUTTON_PIN, HIGH);

#if BYPASS_TIMER_ISR
// disable timer 0 overflow interrupt (used for millis)
TIMSK0&=!(1<<TOIE0); // ++
#endif
}

#if BYPASS_TIMER_ISR
void delayMs(unsigned int ms) {
/*
*/
for (int i = 0; i < ms; i++) {
delayMicroseconds(1000);
}
}
#endif

void loop() {

UsbKeyboard.update();

digitalWrite(13, !digitalRead(13));

if (digitalRead(BUTTON_PIN) == 0) {

//UsbKeyboard.sendKeyStroke(KEY_B, MOD_GUI_LEFT);

UsbKeyboard.sendKeyStroke(KEY_H);
UsbKeyboard.sendKeyStroke(KEY_E);
UsbKeyboard.sendKeyStroke(KEY_L);
UsbKeyboard.sendKeyStroke(KEY_L);
UsbKeyboard.sendKeyStroke(KEY_O);

UsbKeyboard.sendKeyStroke(KEY_SPACE);

UsbKeyboard.sendKeyStroke(KEY_W);
UsbKeyboard.sendKeyStroke(KEY_O);
UsbKeyboard.sendKeyStroke(KEY_R);
UsbKeyboard.sendKeyStroke(KEY_L);
UsbKeyboard.sendKeyStroke(KEY_D);
//UsbKeyboard.sendKeyStroke(KEY_B, MOD_GUI_LEFT);

UsbKeyboard.sendKeyStroke(KEY_ENTER);
#if BYPASS_TIMER_ISR // check if timer isr fixed.
delayMs(20);
#else
delay(20);
#endif

}

}

To the above code i have done small modification ie I have removed. if (digitalRead(BUTTON_PIN) == 0) condition so that the USB keyboard will start typing immediatly after connection the device to USB.But when I flash this modified code and connect the Metaboard to USB I get Problem Installing Device issue .Please help me about it .
