2. Issue faced is, when power in turned off & applied again on entire system(MCU+PS2 converter+usb keyboard), keyboard don't get initialized again automatically, that is I am not able to read any keys unless I remove the keyboard from socket & connect again, then I can read again.

const int DataPin = 19;
const int IRQpin = 18;
c = keyboard.read();
