SOLVED Off brand Gamecube controller help for Dolphin

[davidbrooke]

I'm trying to setup an off brand Gamecube controller to use with Dolphin. Here is a url for the device:
http://www.amazon.com/Retro-GameCube-Style-Wired-Controller-Pc/dp/B00HS7LJ2G

I have tried to use the controller on two different computers with:
genkernel-x86_64-3.18.12 and 4.0.5
with USB HID support

Here is the kernel log when I plug in the controller:
06/16/15 02:50:13 PM usb 3-9 new low-speed USB device number 3 using xhci_hcd
06/16/15 02:50:13 PM usb 3-9 New USB device found, idVendor=0079, idProduct=0006
06/16/15 02:50:13 PM usb 3-9 New USB device strings: Mfr=0, Product=2, SerialNumber=0
06/16/15 02:50:13 PM usb 3-9 Product: Generic USB Joystick
06/16/15 02:50:13 PM usb 3-9 ep 0x81 - rounding interval to 64 microframes, ep desc says 80 microframes
06/16/15 02:50:13 PM usb 3-9 ep 0x1 - rounding interval to 64 microframes, ep desc says 80 microframes

I have reviewed several sites for guidance and this one seems to be the best:
https://steamcommunity.com/app/221410/discussions/0/558748653738497361/
But I can't get past step three since there isn't an dev/input/event for the controller.

Also I have installed games-util/xboxdrv-0.8.5-r1 but this is getting too far ahead since there isn't a dev/input/event for the controller.
Any help would be appreciated.
Thanks

I have finally got this working. I loaded up Manjaro and checked the systemd journal listing - journalctl -f and found the module/driver being used for the Retrolink controller - dragonrise.
I have laid out some basic steps to get it working in Gentoo for Dolphin.

1. Verify dragonrise is loaded:
lsmod | grep hid_dr
If not configure kernel CONFIG_HID_DRAGONRISE
2. Verify joydev is loaded:
lsmod | grep joydev
If not configure kernel CONFIG_INPUT_JOYDEV
3. Verify usbhid is loaded: (this should be loaded if you are using a mouseand keyboard)
lsmod | grep usbhid
If not configure kernel CONFIG_USB_HID
4. Verify via kernel log that the controller is setup correctly:
