+ * Calling this entity a "pipe" is glorifying it. A USB pipe
+ * is something embarrassingly simple: it basically consists
+ * of the following information:
+ *  - device number (7 bits)
+ *  - endpoint number (4 bits)
+ *  - current Data0/1 state (1 bit)
+ *  - direction (1 bit)
+ *  - speed (2 bits)
+ *  - max packet size (2 bits: 8, 16, 32 or 64)
+ *  - pipe type (2 bits: control, interrupt, bulk, isochronous)
+ *
+ * That's 18 bits. Really. Nothing more. And the USB people have
+ * documented these eighteen bits as some kind of glorious
+ * virtual data structure.
+ *
+ * Let's not fall in that trap. We'll just encode it as a simple
+ * unsigned int. The encoding is:
+ *
+ *  - max size:		bits 0-1	(00 = 8, 01 = 16, 10 = 32, 11 = 64)
+ *  - direction:	bit 7		(0 = Host-to-Device [Out],
+ *					(1 = Device-to-Host [In])
+ *  - device:		bits 8-14
+ *  - endpoint:		bits 15-18
+ *  - Data0/1:		bit 19
+ *  - pipe type:	bits 30-31	(00 = isochronous, 01 = interrupt,
+ *					 10 = control, 11 = bulk)
+ *
+ * Why? Because it's arbitrary, and whatever encoding we select is really
+ * up to us. This one happens to share a lot of bit positions with the UHCI
+ * specification, so that much of the uhci driver can just mask the bits
+ * appropriately.
