Description f 2013-04-30 15:44:40 CEST
Using the following command under sigrok-cli starts the dso2250 but the scope fails to trigger (as seen in the log file). The input signal can be any range from 1vpp to 9vpp and the scope still will not trigger. This applies to both channel 1 and channel 2.

/usr/local/bin/sigrok-cli --driver hantek-dso --probes CH1 --frames 1 --device timebase=100us vdiv=500mV triggersource=CH1 coupling=DC -o mytest.txt -O analog -l 5 &> log.txt

mytest.txt is empty. log.txt is attached. The input signal for the log is the 2Vpp @ 1khz calibration signal coming out the scope. Same signal triggers on the opendso software using the same .sys file for extracting the firmware.

all libraries are updated at the time of the bug filing.
 sigrok-cli -V
sigrok-cli 0.3.1
Using libsigrok 0.2.0 (lib version 2:0:0).
Using libsigrokdecode 0.1.1 (lib version 0:1:0).
