I’m trying to get a USB HID PlayStation 4-port adapter working with RetroPie 3.6 on a 512MB Raspberry Pi B.
The device is picked up by the kernel just fine: I can see from dmesg that it’s recognized.
[ 2.025324] hid-generic 0003:0925:8884.0001: input,hidraw0: USB HID v1.00 Joystick [HID 0925:8884] on usb-20980000.usb-1.2/input0
Emulation Station sees this device as a single gamepad even if two devices are connected, but that’s OK for the time being. I can configure the device easily and navigate EmulationStation just fine with it.
I cannot get this controller recongized anywhere within RetroArch, however. I don’t get any yellow message on the screen when any emulator starts – the only input source RetroArch seems to be aware of is the keyboard.
