Description Daniel Elstner 2014-03-04 20:02:01 CET
Pasted report from the mailing list:

I tried run sigrok (and pulseview) on win7 with lwla1034 analyser, but I can't get any captured data.
lwla initialization was OK, but after starting capture lwla not answered.

Running log:

Confirmed, happens for me as well (Win7, 64bit, sigrok-cli/PulseView as of today).
Comment 2 Martin Ling 2015-03-22 12:24:32 CET
This might be related to #343.
Comment 3 Uwe Hermann 2015-03-24 20:19:51 CET
Yep, indeed. This *seems* to fix the issue for now (did a quick test on LWLA1034).

Some more in-depth testing and checking may be in order (once the "full" issue in #343 has been fixed).

For now, this one is fixed in f6c30de4b031ab9a8d838c1ad6ff4118b03c0dc4.

More testing of other users would be great. Please let us know if you experience any further issues.
