Has anyone else had problems getting DFU to work over an EHCI (USB 2.0) host controller? When I perform an upgrade over an EHCI controller, the last packet of every transfer is corrupted.  If, on the same computer, I perform the same upgrade over an OHCI/UHCI (USB 1.0) host controller, the upgrade works fine.  If I trace the transfer at the kernel level using a tool like USBTrace or USBlyzer, all the packets look fine.
