No, USB does not work for tablets. At least not for Android tablets. This would
require root access. However, the next generation Android with the automotive
interface will probably make this possible even without root access.

The thing about CNC control or industrial automation is that there isn't
really that much data being passed. It is much more about latency and
consistency (jitter) if you want a high performance CNC tool.
