I've had good luck with an old-school ethernet<->serial interface from Intelligent Instrumentation: http://www.edasce.com/rs232-ethernet-interface.html It's not USB, but does do the job you describe. I'm able to plop a hub out there on the detector and control multiple RS232 devices through an ethernet connection. They provide C networking libraries which compile fine under linux. -- Alec Habig, University of Minnesota Duluth Physics Dept. [log in to unmask] http://neutrino.d.umn.edu/~habig/
