USB HID Joystick for Dummies

[NatureTech]

Hello all,

I am trying to convert my old joystick to USB Joystick.Since i am kinda new to USB,i plan to take this advantage to learn how USB works.I have tried CDC before & now HID.As a starting point,i searched for a example code & bumped to a site (www.starlino.com),an accelerometer based joystick.I downloaded the codes (which is in PBP) & researched the codes.After going through the USBDesc & tried the code (which worked very well) & i plan to expand it from original (2 Axis & 6 Buttons) to 3 Axis,Throttle & 8 buttons.I have modified the USBDesc & added some lines in source.To my suprise it connects to the computer (ting tong) & showed the axis,throttle & buttons in the gamepad configuration but it freeze in there.Whenever i press any of the buttons,i didn't work..i mean nothing happened.I have tried few methods but didn't work.Can anyone help me??.Attached codes together.

*PS - The attached code is only for x,y,z axis & buttons.

You help is kindly appreciated
