BenBrewerBowman, firstly thank you very much for providing such a library that we can access to joystick values in arduino sketch too.

I am using "USB Host Shield 2.0 Library" and your Arduino_Logitech_3D_Joystick Library to use my "Logitech 3D PRO Extreme" joystick and everything is working nicely. But I was experienced some problem while using nrf24 wireless communication between two arduino devices.

After that, I found a wireless joystick on internet from logitech company and it is similar too "Logitech 3D PRO Extreme Joystick". It's name is "Logitech Cordless Joystick Freedom 2.4".

"Logitech Cordless Joystick Freedom 2.4" is very old joystick and it is the only wireless joystick of its own kind too, I hardly found it on ebay already.

This "Logitech Cordless Joystick Freedom 2.4" is working with "USB Host Shield 2.0 Library"s USBHIDJoystick example sketch; but "Logitech Cordless Joystick Freedom 2.4" is not working with your BenBrewerBowman/Arduino_Logitech_3D_Joystick Library. I don't know why I don't get any reading on serial monitor.

I looked into the USBHIDJoystick example sketch and its cpp, header files and the code written there is more complex than yours; so I failed to modify :(

If it is possible would you make modification on this sketch and its cpp and header files please to access joystick values inside of arduino sketch too ? Then we can use this wireless logitech joystick too.

If anyone has deep knowledge about this "how to make that modification, please would you help ? thank you very much.

"Logitech Cordless Joystick Freedom 2.4" is not working with "BenBrewerBowman/Arduino_Logitech_3D_Joystick Library", would you help how to solve it please ? thank you. #1
