How would I even begin doing this? I have the appropriate resistors to set up a 5v to 3.3v interface (47ohm and 47kohm), from attempting a similar interface (prop to usb keyboard), so that shouldn’t be an issue.
Should I attempt to bit bang the protocol or is there an existing library for this? Following that, is there a chip I can buy that would convert the usb commands to address/read/write commands in a way that the prop will easily pick it up? Or should I not even worry about this?
Sometimes I wonder if reality is big enough for my dreams...
Edit: I am digging through the usb specs for the usb mass storage class and usb 2.0. I must say I am very much in over my head! I will likely be building a usb library, then a mass storage class library, then emulating a usb drive. What fun!
