Hi Alan,
> Are you sure you didn't lose a SETUP packet?
I am not shure in anything in the moment :-) Is that right that a setup packet should have a length of 8 so that they could copied to a usb_ctrlrequest structure? But "my" packet received on Ep0 after enumeration has a length of 24 bytes.
I captured that packet with wireshark:
