[DEV] USB gamepad on official ROM - Galaxy S II Original Android Development

Hi,
after weeks of trying to figure out out the kernel works, I finally managed to have a working USB gamepad on my Galaxy SII !
It's quite buggy/unstable for now but N64oid detected my buttons
It's only working on the official firmware, I'm using 2.3.3 KG1 and only tested on this firmware.
I tested many different gamepads and the only one that I got working is the "Thrustmaster Firestorm digital 3" USB gamepad (it only cost 7 € here !!!)
So what's the steps now ?
- as root "insmod joydev.ko"
- plug your gamepad and type "dmesg" to get more infos about the gamepad detected
- now the gamepad device must have been created : /dev/input/js0
- type "cat /dev/input/js0" in a terminal and when you press your gamepad buttons some weird characters should appear, if not your gamepad is not supported!
- now type "chmod 777 /dev/input/js0"
- install my modified GamepadIME apk
- In Android settings, language and keyboard, check gamepad then select the gamepad IME as the main input method.
- if you're lucky, you'll be notified that your gamepad is detected.
- Your gamepad is simulating a key press so you can see it working in an input area.

It doesn't recognize my dualshock 2 at all and my old WingMan is recognized but the buttons presses aren't.
Great work nonetheless. I hope someone (or you ) can expand on your great work and add more gamepad compatibility.

dualshock 2 is not USB ? I also compiled the full joystick kernel modules (xpad, gamepad,iforce,sidewinder, tmdc etc) so it may help with other ones but as I don't have the hardware I can't check the code.
Anyway, only generic gamepads may work, I really tried hard on the Xbox360 one but failed again and again...

Well... USB devices are supported native in 2.3.4

No, joystick support is added to Android 3 only. Also USB device is a generic word for something that uses USB so only a small part of the whole USB devices is really supported by Android for now (keyboards and mice mainly).

I obviously used an adapter
My PS3 recognizes both the WingMan and the DS2, so I suppose they are generic in some way.

That kind of adapter uses the gamepad kernel module, not the joydev one so that's why it doesn't work.

What did you modify?
I investigated a bit: It's possible to detect button presses without the module and my GamepadIME. But the events are a bit strange. From Activity.onKeyDown() with neither joydev.ko nor GamepadIME:
Code:
KeyEvent{action=0 code=0 repeat=0 meta=0 scancode=306 mFlags=8}
"code=0" might lead to the strange effects I have with NESoid: single button presses seem to activate all buttons at once.
So if the emulator/game developers take care for this and analyze also "scancode" and not only "code",
- it's possible to play games without root/module/GamepadIME with the buttons of a gamepad
- it's possible to play games with root/module/GamepadIME with the sticks of a gamepad or with one of those retro adapters for old digital joysticks.

Can anyone compile joydev.ko for AOSP based roms like MIUI and CM7? Or mabye someone can guide me in compiling this?

---

My experience:
1- copy files (joydev.ko and GamepadIMEAlex.apk) to galaxy S2
2-open root explorer in galaxy S2 and select joydev.ko and copy
open lib folder
open modules folder
click on mounted r/w and now you can see mounted r/o
3- pasted into modules the file joydev.ko
4-open android terminal in galaxy S2
write su (now have super user permissions)
write :
cd lib
cd modules
insmod joydev.ko (and ok 0 errors, terminal do not say nothing)
5- to plug a gamepad and wait 5-8 seconds
6- write: dmesg in terminal and you will can see gamepad detected or not
7- write: cat /dev/input/joydev.ko and press gamepad buttons ,
two things can happen: Nothing or Yes it is running
8- Install GamepadIMEAlex.apk
9- now into ajustements ,
look into keyboard/language and mark gamepad option
and in select input method (select gamepad)
10- good lucky
Ps3 original gamepad Only run bluetooth mode thanks sixaxis 0.32 apk in original stock rom 2.3.4 ,Are not running with usb mode
Ps3 clone-copy gamepad, are not running (not bluetooth, not usb mode)

Can you compile the kernel module also for the CyanogenMod Kernel?
