- * 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 (1 bit)
- * - 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
- * - speed: bit 26 (0 = Full, 1 = Low Speed)
- * - 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.
