My only suggestion is to get diagnostics from sigrok. Try the following commands: sigrok-cli --driver fluke-45:conn=/dev/ttyUSB0:serialcomm=9600/8n1 --scan This should identify the fluke and confirm that communication is working properly. You can also try omitting the serialcomm option, the sigrok-cli example command for scan omits this for its serial based example. You can also increase the log level from 0 (None) to 5 (spew) using the --loglevel option, which may shed some light on the activity you observe.
