The device queue head (dQH) points to the linked list of transfer tasks, each depicted by the device
Transfer Descriptor (dTD). An area of memory pointed to by ENDPOINTLISTADDR contains a group of
all dQH’s in a sequential list as shown in
receive endpoints (OUT/SETUP) and the odd elements are used for transmit endpoints (IN/INTERRUPT).
Device transfer descriptors are linked head to tail starting at the queue head and ending at a terminate bit.
Once the dTD has been retired, it will no longer be part of the linked list from the queue head. Therefore,

Priming an endpoint towards the end of (micro)frame N-1 will not guarantee
delivery in (micro)frame N. The delivery may actually occur in
(micro)frame N+1 if device controller does not have enough time to
complete the prime before the SOF for packet N is received.
