Using usb horipad only one joycon is recognized

[albfan]

Connecting by usb (cannot make them work by bluetooth):

both joycons are recognized but only one /dev/input/js is created (witch all the axes expected for a pro controller), but only one joycon provides input. If a connect/disconnect one of the usbs, js keeps available and the other joycon keeps providing input.

This cheap joycons do not report them as joycons (057e:2007, 057e:2008), but as pro controllers (057e:2009). Anyway is expected that they show as two different controllers. (Would be great to have them as only one without joycond, but that's another story)

Any idea of why both are mapped to same /dev/input/jsN? I can play with code and provide feedback.
