russeree:
You might be interested in my fast USB 2.0 High Speed keyboard design too! It's open source. It doesn't work like yours though since you wire everything directly into the MCU and have some noise suppression tech. Mine instead has to be wired through and FPGA that handles all of the keys, then a MCU receives the digitally filtered output of key interface. It might actually even be a little faster with my latest firmware because now the FPGA just sends a command as the spi master updating the MCU that a key has changed.
