This documents a USB HID driver that permits using the Logitech F310 gamepad with an Arduino.
The goal here is to permit the use of the Logitech F310 gamepad with an Arduino (Uno or Mega) by way of the Arduino USB Host Shield. (other USB host shields may also work, but I don't have them to test).
Install a modern version of the Arduino IDE. I'm using Version 1.8.7.
Install the USB Host Shield Library 2.0, or update it to the latest version. This can be accomplished in the Arduino IDE by using the Tools Menu, Manage Libraries, ...
Get a USB Host Shield and an F310 gamepad.
Important! There is a little switch on the bottom of the Logitech F310 controller that can be positioned at either "X" or "D". It must be set to "D".
A bug has been identified in the USB Host Shield Library 2.0, Version 1.3.2 that needs to be patched before the Logitech F310 gamepad can be used. The patch is documented here felis/USB_Host_Shield_2.0#438
A patched version of the file usb.cpp is found in the "library_patch" folder. Copy this into the install folder for the
USB Host Shield Library 2.0 and you will be fixed up. The install folder is different on various computers. On a Mac
it's Documents/Arduino/libraries/USB_Host_Shield_Library_2.0/. In Windows 10 it's
My Documents\Arduino\libraries\USB_Host_Shield_Library_2.0\.
The demo code is located in the lf310 folder. It is a HID-based USB driver, similar to the SRWS1 sample code that ships with the library.
