I hope I have the required understanding. At least the Flex USB
adapter seems to work! The firmware is only a couple of hundred of
lines of 8051 assembly code, but probably not very useful for your
project. Instead of people having to decipher my code (or the parallel
port code in PowerSDR), it would be better if someone wrote a short
document describing the I/O sequences. Maybe I can do that.

I checked this. It's "only" about 5000 operations!
