Hi Myles,

Sorry if my short answer sounded abrupt. I just looked through your output 
and it looks like it's mostly working for you since I can see that it 
retrieved the product ID (LEGO) and the type (SONAR) from the sensor.

Try doing a for() loop that spits out distances and you will see that it 
gives good readings most of the time.

There's also a temporary workaround someone mentioned that if you use 
NXTCommand.setVerify(true) before calling methods on the Ultrasonic sensor 
it will become pretty much 100% reliable, except for the getDistances() 
method. Hopefully everything will be fixed up for iCommand 0.6.

All the best,

- Brian
