- * Calling this entity a "pipe" is glorifying it. A USB pipe

- *  - pipe type (2 bits: control, interrupt, bulk, isochronous)

- * That's 18 bits. Really. Nothing more. And the USB people have

- * virtual data structure.
- *
- * Let's not fall in that trap. We'll just encode it as a simple

  *
- *  - max size:		bits 0-1	[Historical; now gone.]
  *  - direction:	bit 7		(0 = Host-to-Device [Out],
