PicoScope segfault on Ubuntu 16.04

Hi, I'm trying to run Picoscope 6.11.13.3, to connect to a DrDaq data logger.

I can never connect to the DrDAQ and I get a segfault with the log below.
The board works fine on windows, and the usbtest doesn't report any problem...

Any idea about how to make it work ?
Many thanks

Hi Ben,

This appears to be a software issue and has been reported to the Development Team.

Hi,

Thank you very much for your answer !
Is there a new release for linux scheduled ?

Many thanks,
Ben

Hi Ben,

There should be a new release but we do not have information on any timescales at this moment in time.

Regards,

Hello

I have the same problem on Ubuntu 16.04 and picoscope 2206A

Is there any news about a new release with a fix for this issue?

Is there an old version of the software that can work on Ubuntu 16.04?

Thanks
Nicolas.

Hi Nicolas,

Please e-mail support@picotech.com and we will see if we can provide you with an older version.

With regards to the segmentation fault, it would be useful to see the trace.xml corresponding to the session where this occurred.

Repeat the issue, then find the trace.xml file in the following location:

~/.local/share/Pico\ Technology/260a68f1-30f-0a5e01d65514

You can send this file by e-mail as well.

Regards,
