Hey John, Thanks for the input here!
In our recent prototype, our sensors were directly connected with some minor filtering. In the next iteration of our hardware design, we plan to have a driver in between (similar to your suggestion). Our software is communicating through a hardware server written in JS. The other half of our software is a UI server that interfaces with the user. We did have log files on the hardware server that allows us to see some of the commands, but that is helpful advice on using dmesg/syslog to check as well!
