ZX81 USB Keyboard Source
I started the code for the ZX81 USB keyboard, with the USBKeyboardDemo1 sample in the Arduino Version of the V-USB library. As stated in the original post, either change the config.h file in the library to set USB_CFG_DMINUS_BIT to 3 rather than 4 or wire up the circuit with 2 and 4.
