Timeout error NI DAQ recording encoder Position or EdgeCount using clock

I wish to record timestamped data from a quadrature encoder using an NI DAQ USB-6341 but I receive the "timeout" error below. Thank you for your help.

>>[data, time] = s.startForeground()
Timeout expired before operation could complete.

This script works correctly (Analog channel only, third line commented-out):

s = daq.createSession('ni');
addAnalogInputChannel(s,'Dev1', 0, 'Voltage');
%addCounterInputChannel(s,'Dev1', 0, 'EdgeCount');
s.DurationInSeconds = 0.25;
[data, time] = s.startForeground();
plot(time, data);

This script gives the timeout error mentioned above (third line active):

s = daq.createSession('ni');
addAnalogInputChannel(s,'Dev1', 0, 'Voltage');
addCounterInputChannel(s,'Dev1', 0, 'EdgeCount');
s.DurationInSeconds = 0.25;
[data, time] = s.startForeground();
plot(time, data);

This script (analog and digital single scans) works correctly too:

s = daq.createSession('ni');
addAnalogInputChannel(s,'Dev1', 0, 'Voltage');
addCounterInputChannel(s, 'Dev1', 0, 'EdgeCount');
data = inputSingleScan(s)

I based those scripts on the examples which I cannot run fully (timeout error above) from:

Thank you,

I am having the same issue, same daq. Hopefully someone can help.
