Endpoints

Hello,

As I read in the specification it is allowed to have up to
16
Endpoints. But what is the minimum? Endpoint 0 (type
control) is
always required. But do I really need an Endpoint 1,2...15?
If I don't
need other Endpoints than EP0 do I need the Interface and
Configuration descriptor?

Thanks in advance,
Hannes Riedenbauer

AFAIK EP0 is enough, but you need the descriptors (from my
understanding
of USB, I don't know about the core).
