Mega32 as Xb*X gamepad

[Grobi]

Hi folks,
I am trying to implement an Xb*x gamepad with this firmware, but having some problems with that.
For testing I connect it to a PC with latest XBCD drivers but the device failes enumeration 'cos of not sending a Device Descriptor, thats what the prog USBLyzer told me.
I tried an original Xb*x gamepad which works on my PC and USBLyzer gives me these information about the device :

XBCD XBox Gamepad

i want my device to mimic the Xb*x gamepad i have and modified "usbconfig.h" :

so, I am stuck, I have no idea on how to solve this and make it work.
Maybe somebody could have a look at this and could give me some advice on how to fix this.
I don't think that the speed difference ,original pad fullspeed, my device low speed, prevents it from working.

Mega32 running on 16 MHz

thx Grobi

[Grobi]

nobody?

[Grobi]

ok is anybody able to have a look at the usbconfig.h and usbdrc.c so that the configuration is similar to the Xb*x gamepad data I posted, because I am not sure if all data is set correctly (high and low byte order of values).

Thx Grobi

Hi , I know its been a bit here, but any luck with this. I just started the same venture to day. Plan on doing the same thing as you..


Ok, I got it to work. Look like you no longer are a member? but took a few hours to get it work so if you return one day look me up.

[bencao74]

Hi,

I'm interested in your work. Could you contact me about your solution?

[ulao]

as soon as I find the pm.

OK for getthat I found you on the net, log in to you tube;)

Dear Ulao -

Are you emulating an Xbox controller? Is it an Xbox or an Xbox 360 controller? I've been looking around for people trying to emulate a 360 controller, but I haven't found anything. Would you be willing to share your code with me and my project? You can find it at http://www.OpenChord.org ...

Thanks,
Alan Chatham

-I'm able to act as an xbox, not read it. In other words the xbox thinks I'm ( avr controller ) a official xbox controller. The 360 has a security dongle of sorts in it. So no I can not emulate it and so far nor can anyone else. m$ has got us all stumped on this. As far as sharing code, its just a mangled descriptor. All you have to do is change a few things and make the xbox think you are an Xbox controller.

this is how I set it up.

Code: Select all

const char usbXboxDescrDevice[] PROGMEM = {  
    0x12, //size of this descriptor in bytes
   USBDESCR_DEVICE, //descriptor type = XBOXUSB_Device_Descriptor
   0x10, 0x01,    //USB Spec 2.0
   0x00,        //class code
   0x00,        //subclass code
   0x00,        //protocol code
   8,//  0x40,        //EPO buffer size
   0x5E, 0x04,    //vendor ID 04D8
   0x02, 0x02, //product ID
   0x00, 0x01, //device release number

   1,          /* manufacturer string index */
   2,          /* product string index */
   3,          /* serial number string index */
   1,          /* number of configurations */
 };

After doing this my device was seen as a xbox controller. You may have to play with the usbHidReportDescriptor a but to get it right.

[Grobi]

Hey Ulao, I am glad to hear that sombody has got that thing working, I am very interested in your solution.
My project laid on ice since yesterday, found it in the basement, and I am willing to continue it, maybe you could give me some advice or some examples, I knew that it is possible and there has to be a way on how to solve this but over the weeks I forgot about the whole thing.

...do i really need an hid report descriptor? i've read almost everywhere that the gamepads lack those descriptor.
I tried to use your device descriptor but the device isn't recognized, not in dashboard, not in xbmc and not even on a wind*ws system.
Do you use one endpoint or two?

...man I can't make it work,
I put up a lil test-prog without the whole PS2 mouse and keyboard stuff but it won't work either.
Please, if you could spare some time and have a look at the code and maybe compare it to your solution and tell me what the heck I am doing wrong?

on a wind*ws system I get an Device is not recognized error when I plug it in but I think thats normal for an Xb*x gamepad...

Do your self to favors. 1) get xbcdhttp://www.redcl0ud.com/xbcd.html 2) get USBlyzer. Once the xbcd is installed it will show up as a xbox when you connect a real xbox or this avr. Tell me what you learn. I will look over your code later, when I have time.

[Grobi]

Usblyzer :
Enumeration of device failed.
USB get node connection Information, all values of DeviceDescriptor are 0x00 that can't be right.
