I have Knoppix 9.1 installed on two flash drives and a DVD.
They all work on my work machine. (16 years old)

I have been building a new desktop machine.

One flash drive stops at the second line.
The second boots up but doesn't recognise the wired keyboard.
The graphical keyboard that comes up refuses accept my key sequences and certainly cannot pass them anywhere.
I have never had problems before.

Any suggestions?
