I just got the 2205A and have managed to run it on Ubuntu 16.04.
When the application starts the default resolution is 50us/div with 16kS.
Everything works ok up to 5s/div 16kS, however switching to 10s/div or higher
stops the graphing.
The application itself is still responsive so going to File->Connect device enables reselecting the device,
some relays in the scope click, and it's working again with 50us/div with 16kS.
The software and hardware versions in use are:
PicoScope® 6 - PC Oscilloscope software version: 188.8.131.52
Copyright © 1995-2016, Pico Technology Ltd.

USB Version: 20.0
Calibration Date: Thursday, May 19, 2016

Anybody has a workaround for this situation?
