Definitely I'll stick with 12Mb/s USB to start (for sure on our
wire-wrapped prototype board) but I'd love to boost that to 480Mb/s

to high-speed but also whether the FPGA without special serial hardware
can go that fast. If it can, fantastic. I'll take all the pointers I
can get.

that the one I use a lot...
You use container files in fat16, or simply 1:1 block mapping?
1:1 block mapping. I'm going to have enough fun with trying to
implement the USB stack in the FPGA without doing FAT16 too.
Yikes ;-)
Please do yourself a favor, and put a small micr0controller in the FPGA.
Get it working, then you can optimize and write HDL for it.
What FPGAs are you using?
I agree some how with your approach, but it leads to debugging of
issues, you wouldn't have on real boards ...
No doubt. It's been a learning experience and we still have a long ways
to go.
You will learn a lot on this way ...
