Created attachment 68772 [details]
create joystick devices for both gamepads connected to a HuiJia USB Gamepad connector

Actual Results:
When I connect a HuiJia USB Gamepad (a connector for two SNES gamepads) to my computer, only one jostick device shows up, handling the inputs of both gamepads.

Expected Results:
Each gamepad should be detected as a separate joystick.


Attachment:
The attached patch leads to the expected result, but altough two jostick devices are created, four events are created, too.
I am not sure, what event 9 and 10 do, though.
