Description Bert Vermeulen 2014-10-27 12:24:19 CET 
On selecting the device found by the hantek-dso driver in the dropdown:

When I do 'continue' in gdb and click the 'Run' button:

Comment 1 Soeren Apel 2016-11-04 23:03:48 CET 
Is this still an issue?
Comment 2 Uwe Hermann 2016-11-04 23:41:38 CET 
Created attachment 269 [details]
gdb log
Comment 3 Uwe Hermann 2016-11-04 23:42:09 CET 
Yup, still reproducible with git HEAD as of today. Updated gdb log attached.
Comment 4 Uwe Hermann 2017-12-27 20:35:21 CET 
OK, this one seems to have been "accidentally" fixed along the way, no longer reproducible on two different boxes, with or without the firmware being accessible by libsigrok.
