Composite HID using LPC1769

[lpcware]

Hi,

I'm trying to make the USB HID example for LPC1769 into a composite HID device that can support more the 1 HID interfaces.  What I have done so far is  modifying the usbdesc.c file to accomodate 2 HID interfaces. Device failed to enumerate. Anyone have tried something similar? Any pointer is greatly appreciated.

PS, I have succeeded in making a composite usb device for generic non class bulk transfer end points by doing the same thing

Thanks,
Chop

Hi Chop,

maybe these links/tools may help you to analyze the problem:
http://www.usb.org/developers/hidpage/
http://www.usb.org/developers/tools/

Download the HID Descriptor Tool from the HID page and the USB command verifier USB20CV from the tools page. Maybe you need also to download the company list on the bottom of the tools page to get the CV to work.

I don't have used these tools yet because I'm currently just at system design, but maybe these tools will be helpful.

Regards,

Ralf
