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: Select all
rom const unsigned char PS3USB_Device_Descriptor[] = {
0x12, //size of this descriptor in bytes

};

};
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?
