Hi

I've got one of those USB 3G dongles which appears as a networking device and also as a cdrom (containing drivers). Is it possible to do this with a single chip, and if so, is the 8U2 capable of this. Or, have they integrated a SUB hub into the device and added two separate devices? Tried searching, but couldn't find much.

Cheers

Doesn't the LUFA documentation say anything about that?

In theory USB supports more than just one 'endpoint' (or whatever it is called) per device. The pololu usb programmer does just that. serial + isp in one chip.
