4 gamepads not recognized on LINUX
Posted: Fri Jun 26, 2009 11:55 pm
Hi,
I'm working on a module to connect 4 Nintendo64 controllers to PC via USB.
I'm almost finishing it, but I have a problem, my hid descriptor has 4 identical devices identified by the report-ID. OK, on windows this works fine but on Linux they don't appear at the /dev/input as joysticks. They appeared as one single file called event6. When I take 2 controllers from the hid descriptor, leaving only 2 they work fine on both O.S.'s . But on linux they appear just as one big controller with 4 axis and 32 buttons, but they have half of these each. On windows at all cases they appear as separate controller.
Here is my descriptor:
Anyone have ever done something like this to help me?
thanks, sorry for the bad english...
