Full pulseview log

Quite likely a duplication of bug #1049 but on linux also.

Unable to connect to DSLogic Basic when using PulseView on Ubuntu 16.04. Using latest git versions of libsigrok, pulseview, libsigrok-utils, etc.

Latest firmware versions downloaded and renamed using sigrok-fwextract-dreamsourcelab-dslogic from libsigrok-utils. Here is the relevant output of pulseview with log level set to 5; initial start then attempted to connect manually a couple of times (full log attached):

Firmware appears to load however pulseview cannot connect due to the reported firmware not matching the expected response. Reported firmware number changes with each attempt to connect, although 160.0 on the first attempt does seem to be quite consistent.
There is no change to lsusb pre or post firmware upload.

Cheers
Wayne

Yup, it's a duplicate of #1049, marking as such. I can reproduce the issue on Linux and Windows with DSLogic (original) and Basic and Pro as well. At the moment I seem to be getting "Expected firmware version 1.x, got 0.0." consistently. Could be something timing-related, or some upstream change we have yet to identify and account for.

Anyway, we should continue this at #1049.

Correction, when I said "Pro" I meant "Plus".
