hello my friends!!
I want to implement a composite driver for a token that is designed base on at91sam7s256 , I want to have a multidevice token (mass storage , HID keyboard , CD Rom).
at this time I implemented the HID keyboard on it but I need a composite driver.atmel has provided a document with this title "AT91 USB Composite Driver Implementation" but it contains only sum of drivers such as MSD+HID but I want a code that implement three device .
Or I want the code that implement the "cd rom "device with usb, that I can use it with other 2 device.

thanks a lot for your attention and responses my friends!!!!!!!!!1

The data sheet says that chip has 4 endpoints, you're using 1 for control, so you only have 3 left (2 bulks and an interrupt). the 2 bulks will be used for the mass storage, leaving 1 interrupt which can be used for the hid (as they are in their MSD+HID Demo I presume). You won't be able to add a cdrom to that list with that chip.
