98	* IO buffer sizes and FTDI device procotol sizes.

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