+/*
+ * Force feedback support for PantherLord/GreenAsia based devices
+ *
+ * The devices are distributed under various names and the same USB device ID
+ * can be used in both adapters and actual game controllers.
+ *
+ * 0810:0001 "Twin USB Joystick"
+ * - tested with PantherLord USB/PS2 2in1 Adapter
+ * - contains two reports, one for each port (HID_QUIRK_MULTI_INPUT)
+ *
+ * 0e8f:0003 "GreenAsia Inc. USB Joystick "
+ * - tested with König Gaming gamepad
+ *
+ * 0e8f:0003 "GASIA USB Gamepad"
+ * - another version of the König gamepad
