In order to emulate a PS3 controller, I am trying to use the PS3's own HID report descriptor, which should be as described here:
http://ps3.jim.sh/sixaxis/usb/lsusb.txt

I admit that I do not understand most of it, there are some portions which are really strange, such as the 13 bits right after the buttons, which maybe serve for padding. And then there are the additional collections at the end (5 times 48 bytes!!!). Anyway, if I ignore those last bits, I would end up with a 9 bytes reportBuffer, which is not acceptable for V-USB.

Does anyone have any hints on how to move on from here?

Thanks
Christian

according to the source from UPCB Toodles has taken exactly this way.

//HID report from VSHG; need to double check.
rom const unsigned char PS3USB_Report_Descriptor[] = {


This was the VSHG http://sdtekken.com/tech-area/arcade-sticks/ps3-vshg/virtua-stick-high-grade-review/ Stick.

Hope you've better luck!

I think part of the problem is the HID descriptor. The one used by the UPCB is not the standard Sixaxis one. I think the best option will be to copy one from an arcade joystick for the PS3, which I am going to try doing at some point.

this is my first post in this forum. I'm quite a beginner in using this great piece of hw/sw.

Some month before I found a USB gamepad implemenation based on V-usb and adapted it for my needs in building an arcade stick.

http://bencao74.blogspot.com/2009/09/lulu-source-released.html

It was easy and straight forward to adapt the source. I've extended the source to use 10 Buttons and a stick. Then I wanted to use my arcade stick on the Playstation 3. I observed that the home button is not working. Since this a important function for PS3 I tried to identify it in the pc usb gamepad implementation, but no success.

I found a project called UPCB http://forums.shoryuken.com/showthread.php?t=131230 that supports the PS3 on the basis of PIC18F4550.

I tracked down the source to the PS3 descriptors (http://www.marcuspost.com/downloads/upcb/UPCB_25.zip)

I mapped the descriptors to my v-usb controller implementation. The device is recognized, but winxp setuppi.log says that my device could not be started (error 10). Here're the descriptors of the UPCB project.

Code: 

rom const unsigned char PS3USB_Device_Descriptor[] = {
   0x12, //size of this descriptor in bytes
   DEVICE, //descriptor type = PS3USB_Device_Descriptor

 };



Now I'm getting out of ideas. What do you think about this approach? Does the v-usb cover the requirements that UPCB PS3 implementation needs? How can I get more infos to tackle this issue?

Bye,

Bencao
