One fundamental problem (at least given the SAM7 register set) remains: I have no indication to decide which of the data OUT packets was the last, and when the device should return the status stage IN packet. Since (at least in my application, don't know whether this is how it is supposed to work) the setup state states the length of the data, I simply use this as indication. Seems to work just fine now. I spent already more than one day at this problem ;( Thanks once again.
