Can't get past initialize state

In initialize, it never gets past write(0xff) only prints "try write". I think the pin never goes low, so it gets stuck in the loop:

while (digitalRead(_clock_pin)) {;}

Any advice?

Also, may want to change to include Arduino.h instead of WConstants or whatever.

void PS2Mouse::initialize() {
  Serial.println("initialize");
  pull_high(_clock_pin);
  pull_high(_data_pin);
  delay(20);
  Serial.println("try write");
  write(0xff); // Send Reset to the mouse
  Serial.println("end write");
  read_byte();  // Read ack byte 
  delay(20); // Not sure why this needs the delay
  read_byte();  // blank 
  read_byte();  // blank
  delay(20); // Not sure why this needs the delay
  if (_mode == REMOTE) {
    set_remote_mode();
  } else {
    enable_data_reporting(); // Tell the mouse to start sending data again
  }
  delayMicroseconds(100);
  _initialized = 1;

  Serial.println("done");
}

There are some more recent forks that have some fixes in them for more recent adruino version or feel free to fork and make the changes. I don't maintain this library anymore

Cheers, Kris

Serial.println("done"); }
