This series of patches provide input support for the Logitech G920 gaming wheel. This wheel is internally different from the other Logitech wheels; when first connected it is in X-Box mode and can instructed to switch to HID with a 'magic command' (1st patch). Once the wheel reconnects in HID mode it can communicate with the HID++ protocol, but using a 'very long' packet size (2nd patch). Basic input operation is possible with adustment of the 'range' (the amount that the wheel turns) controlled via the '/sys' interface, same concept as the G25/G27/etc. We also discovered that wheel uses some vendor specific pages, which confuse the HID system resulting in lots of additional axis reported. This is prevented by ignoring these pages (5th patch, thank you Elias). Note: These patches are applied to Jiri's 'for-next' tree to work with the other HID++ changes already queued for 4.4. The future... as the internals of the wheel are considerably more 'capable' we are working on implementing Force Feedback using the forth-coming KLGD system.
