| How to use more than 1 device in USB HID descriptor? |
 Posted: Fri Sep 07, 2007 12:49 pm |

i'm programming a interface to PSX controls but I don't know how make more than one gamepad device
here is my descriptor
can anyone help me?

what drivers did you use on the windows side?
also how did you send the commands from the PIC side? basically do you have information that would allow me to make a similar device?
also do you know how I can use CDC mode at the same time to allow me to have a Joystick & Serial interface? |

sorry for my english

I use the hid class, because that i didn't need to create a windows driver.
| ratgod wrote: | | also how did you send the commands from the PIC side? basically do you have information that would allow me to make a similar device? |
in the begin of my code there are a HID configuration and there i configure the bytes that i will send in USB
| ratgod wrote: | | also do you know how I can use CDC mode at the same time to allow me to have a Joystick & Serial interface? |
I used a composite device ID and Vendor ID, I need to look to remenber the number
did i help you?
i can post a complete code if you want |

I'm currently away on business so I don't have a chance to try it out till wednesday, but posting the complete code would be nice, that way I can see what goes on.
thanks |
