USB Composite Device for LPC134x

Hi,

I've created a firmware application for USB composite device in LPC1343, I found an example for this Micro controller which is the composite device is composed of CDC and MSC in AN11018 from nxp for my reference. What I did I've created a composite driver using USB HIDROM and USB MSCROM running in Keil, but unfortunately when i run the firmware it didn't enumerate the device. I used both of the on-chip driver of the LPC1343 for this firmware application. It is possible to combine this two?
I combine the code sample of on-chip driver for HID and MSC into one file but different function on each and call in the main function, but unfortunately it didn't worked. When I checked on the Device Manager, I found a "USB Mass Storage" with a warning sign (exclamation point). I think the device doesn't enumerated
properly.Could someone help me about this?

Thanks.

    You should not "combine" USB ISP code with your USB application.
    Bootloader should be independent from your application code, to guarantee recovery from failed firmware update.
