Universal Serial Bus Interfaces
The asynchronous list is a simple circular list of queue heads. The ASYNCLISTADDR register is simply
a pointer to the next queue head. This implements a pure round-robin service for all queue heads linked
into the asynchronous list.

high-speed isochronous endpoints. All other transfer types should use queue structures. Isochronous TDs
must be aligned on a 32-byte boundary.
21.5.3.1
The first DWord of an iTD is a pointer to the next schedule data structure.
