* HID driver for Xin-Mo devices, currently only the Dual Arcade controller. |
|
* Fixes the negative axis event values (the devices sends -2) to match the |
|
* logical axis minimum of the HID report descriptor (the report announces |
|
* -1). It is needed because hid-input discards out of bounds values. |
|
* (This module is based on "hid-saitek" and "hid-lg".) |
