Below is a 2 part question I submitted to Cypress Tech support.   
Their response ( not shown ) does not answer my questions.
It mostly repeats spec sheet information. CT does not address my  
concerns with the host end , they talk
about the client end ( which in my case would be an FPGA ).  I would  
rather the host end be easy to deal
with ( using built-in host support ) and spend more effort on the  
FPGA end.

  Anyone who has worked with USB 2.0 High Speed might have some  
insight to share with me.

Part Number:  	CY7C68023
Product:  	Universal Serial Bus - USB High-Speed Peripherals > EZ-USB  
NX2LP / NX2LP-Flex
Subject:  	High speed USB Host to Cypress USB/FPGA combo
Description:  	What would be the best way to transfer data between a  
Host ( Linux, Windows, and OS X ) with USB 2.0
and a combination of a cypress USB chip married to an FPGA ?

1) If I use a NAND flash chip such as the CY7C68023 then the  
combination USB/FPGA will look like a set of files.... is this  
correct ? This will make the Host side easy to manipulate since I can  
use file support from the operating system. The FPGA will have to  
preserve the correct file format when changing data.

2) Using a CY7C68013 would require more work on the Host end, would  
it not ? To the Host it would not look like any standard method of I/ 
O. Is that true or not ?

I would rather deal with adjusting the USB/FPGA combo and having  
something standard on the Host end. I can find development  
environments that deal with files on storage devices, serial ports  
and such much more easily than having a custom driver for each  
platform ( Linux, WIN, OS X )

What I am concerned about ( and perhaps I am missing something  
obvious here ) is what the USB connection looks like to the HOST PC.

4) Will the CY7C68023 look like a disk drive to the host ? This would  
make it easy for the host to deal with the USB connection.
5) What will the CY7C68013 look like to the host computer ? A disk  
drive or something else ?

I am more concerned with making the host end multi-platform and easy  
for host programming.
6) Would not Linux, Windows XP and Mac OS X think a CY7C68023 was a  
disk drive ?
7) What would these OSes think a CY7C68013 was ?
