I see you and Pantelis talking about if some changes were really needed in composite.c or not, but nothing about dfu-utils. Were you objecting to the composite.c changes because you didn't need them, or because they in turn broke trats (can I get one of these somewhere?) The only other unresolved thing was about board_usb_init() which I think was settled on trats needing to change behavior. -- Tom
