^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3)  *  HID driver for Xin-Mo devices, currently only the Dual Arcade controller.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4)  *  Fixes the negative axis event values (the devices sends -2) to match the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5)  *  logical axis minimum of the HID report descriptor (the report announces
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6)  *  -1). It is needed because hid-input discards out of bounds values.
