Thanks mwall for the insight & help! I was struggling to get my Acurite 01536 running on an Odroid C1 (Ubuntu). I was having a problem similar to Steve's, however for me weewx was able to consistently find the station on the usb port but also consistently gave a Broken Pipe error. The solution was a powered usb hub. Thanks again!
