2. The characters are stored using interrupts but the interrupts are re-enabled only when parse it. This may cause the keyboards internal buffer to be overwhelmed.
I did allow enough time for the keyboard to start. I see the LEDs flash, so I think that is not the issue.

I will follow you suggestion and look into the buffer situation. I will also order a 40mhz oscillator just to be sure.

I will report back on my progress.
