97  * IO buffer sizes and FTDI device procotol sizes.

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.
