I am currently working on Cambridge's Baking Pi Lesson 10; My problem is that although all text is displayed correctly, none of the keyboards that I have tried have been compatible with Chadderz's Simple USB Driver. Is there a list of compatible keyboards?

In a previous post I've reported fixes to the driver for my keyboard - one issue was that the driver retrieves an array of keys that are pressed and the number of keys pressed, and assumes that if there's one key pressed its the first in the array, which was not the case for my keyboard. The other is an issue with the DMA buffer sizes causing memory overwrites. You could try applying the fixes to the driver or debugging your issue.
