ps2000Con unable to open device (Ubuntu 18.04)
Hi,
There was an earlier post on this, but it doesn't seem relevant since the drivers seem quite new.
I have a fresh install of Ubuntu 18.04.2 and a brand new PS2207B. I installed via apt. The /opt/picoscope/lib/ has a library version 2.0.0. The picoscope application seems to work fine, and shows me good traces. Running the usbtest script shows correct permissions: the device has group 'pico' and so does my account. I checked by hand and all appears well.
I've compiled the ps2000Con from a fresh checkout of the git repository (both compiled by hand and with the autogen script) and it compiles and runs ok, but...
Because the 'ps2000_open_unit' call is in the library, I can't get any farther: there's no source code or exported debugging symbols.
I've tried repeatedly opening the picoscope app, closing it, and running the command line. All the picoscope trials work, all the command-line ones don't.
What do I try next? Is this release buggy on this operating system?

For the 2207B you need to be using the ps2000a examples from our GitHub page the code you have is for the older 2000 series models.
