Xbox Chat headset with GIMX ?

Post by 0uistyty » Tue Oct 23, 2012 9:48 pm

HI all,

Did someone find a way to connect Live chat headset (one that must plug into a pad) while using GIMX ?

Actually using the kinnect microphone that work pretty well but the chat output on TV is really really bad. I don't hear half of the thing that people are saying.
Voice setting are in Xbox : Voice at level 10 and Game at level 1

No chat sound level in game (COD MW3)

Any hint will be appreciate.

Hi Malto,

I want to give a try on that "evolution" but I would definitively need some tips.

I'm still novice in hacking and devlopement.

I would like to be able to dump the output of the mic of the headset connected to xbox controller on a linux system.

running xboxdrv on ubuntu 11.10 I'm able to get activity when the headset is plugged in or plugged out but i'm not able to capture mic activity. (I get all other sticks and buttons activity)
I'm pretty sure that the xboxdriver do not get the output out the Descriptor (3) but only the trigger sent when the headset is plugged in or out.

Did someone overhere was able to get something out of this mic ?

My first goal are :
- to understand how the audio is transmitted and received from the controller to usb to the xbox.
- what trigger is sent to xbox when the headset is plugged in or out

My final goal is :
- try to add the headset feature to GIMX project by using audio in/out from controller source or alternative sources and emulate the good output to the xbox 360. Submit the modification if i'm able to make it work.

Help would and will be appreciated.

Regards

Hi,

You can interface with endpoints 3 (microphone) and 4 (speaker) through either a custom kernel module or through a user-land application using libusb.

I've been playing all night with usbmon, WireShark, libusb, xboxdrv and sample here and there to manga how to obtain the data from the mic.
It's look like I missed somthing because I wasn't able to get my voice dump and replay. trough the controller :(

Mabee we are not looking at the good place.
While using usbmon and xboxdrv, I noticed that there is other activity when headset is conntected/disconnected.
Mabe it is related.


Headset Speaker :
- Device 2
- Interface 1
- EndPoint 4

???? (sécurity chip, chat pad, other ?)
- Device 2
- Interface 3
- EndPoint 64
if it is the security chip, will we something like the usbspoof to make a pseudo headset detected by the xbox ?

All my efforts didn't serve today.
I would stronly apreciate if you have a c or c++ code sample that can dump the audio from the mic of this headset/pac combo.
Thanks.

This is the source code for the xpad kernel module:
http://git.kernel.org/?p=linux/kernel/g ... ads/master

There are a few words in the header of the function xpad360w_process_packet.
