so I was trying to control a bot wirelessly with the help of ps3 controller and USB host shield, i am using Arduino UNO as micro-controller. I was able to connect PS3 controller with Arduino and checked all button presses. It works very smoothly for button presses and shows on serial monitor which button was pressed without any lag. But the issue I am facing is that when I try to call any function on button press, the entire function is getting executed and execution comes back to void loop but Arduino stops accepting commands from ps3. But it shows that PS3 is still connected and the connection isn't lost. I went through different blogs and I found out that some say that issue is with new HOST SHIELD library 2.0 and some say that UNO computation takes time. this is what I have tried.

I haven't connected to bot. I was checking whether function are being executed on button press or not or serial monitor. so there cannot be issue of power supply. problem is PS3 still remains connected, also line of execution returns to void loop, then why it stops further commands. please please do suggest any ideas and methods by which I can solve this problem. thank you.

I found that when you use delay inbuilt function, it completely blocks Arduino from accepting any command, that causes some communication barrier. Although ps3 remains connected, it doesn't accept commands. so all you have to do is to remove all delays from your function and build logic based Millis.
