97 * IO buffer sizes and FTDI device procotol sizes.
98 *
99 * Note that the output packet size in the following defines is not the usb
100 * protocol packet size based on bus speed, it is the size dictated by the FTDI
101 * device itself, and is used only on older chips.
102 *
103 * We allocate buffers bigger than the hardware's packet size, and process
104 * multiple packets within each buffer. This allows the controller to make
105 * optimal use of the usb bus by conducting multiple transfers with the device
106 * during a single bus timeslice to fill or drain the chip's fifos.
107 *
108 * The output data on newer chips has no packet header, and we are able to pack
109 * any number of output bytes into a buffer. On some older chips, each output
110 * packet contains a 1-byte header and up to 63 bytes of payload. The size is
111 * encoded in 6 bits of the header, hence the 64-byte limit on packet size. We
112 * loop to fill the buffer with many of these header+payload packets.
113 *
114 * The input data on all chips consists of packets which contain a 2-byte header
115 * followed by data payload. The total size of the packet is wMaxPacketSize
116 * which can change based on the bus speed (e.g., 64 for full speed, 512 for
117 * high speed). We loop to extract the headers and payloads from the packets
118 * packed into an input buffer.
