what am i looking at is to interface (hardware level) with usb thumb drive, without a computer, obviously one wire is data in, and one is data out,
I am mostly interested in the basic functions, how to access a specific memory block, save a bit(or byte), and read that bit(byte)
im obviously looking at serial data, is it 8 bit + parity?
cant use micro-controllers, I am going to import the data parallel using simple switches, then convert it to serial to input to the drive,
a good example is a circuit that can go through the drive blocks, write some 1's, then go back through and read back those 1's, maybe with a counter or 2to see how many ones it read/wrote.
any help would be great, even what this code type is called could help, so far i can't find anything on accessing these things.
also i may want to hack the clock to make it run on external(to slow it down)
