Host Controller Driver
The basic building blocks for communication across the interface are Endpoint Descriptors (ED,
4 double words) and Transfer Descriptors (TD, 4 or 8 double words). The host controller assigns
an Endpoint Descriptor to each endpoint in the system. A queue of Transfer Descriptors is linked
to the Endpoint Descriptor for the specific endpoint.
