State-Changed-Why:
SPD on the data phase of usbd_get_initial_ddesc where 64 bytes are request
would terminate the TD chain as less than 64 bytes were coming back. This
means the status stage never get executed by uhci.

Additionally, setting UHCI_PTR_VF on control transfer TDs executes the stages
too quickly for the device.
