That byte I was getting on the ADB must be right

After careful consideration and analysis, I’ve concluded that those bytes the mouse returned to me were genuine.

For one, the mouse returned 2 bytes of data. According to the ADB specification (and this helpful signal diagram) a peripheral should return, at minimum, 2 bytes (max of 8).

Secondly, after many resets, I get consistent results.

Once I create a reliable method to decipher the ADB serial data, I’ll move onto another register in an attempt to extract location info.
