cannt find Analog discovery2 DAQ device

I tried using Analog Discovery2 DAQ device in matlab to acquire data. I have installed support package for it and all versions of waveform softwares as a driver. After that, I still can't get matlab talk with AD2 DAQ.

This command works: s=daq.createSession('digilent');

but this command didn't work: ch1=addAnalogInputChannel(s,'AD1',1,'Voltage');

When type in this command: daq.getDevices

ans =

No data acquisition devices available.

///// daq.getVendors()

ans =

Number of vendors: 2

Hej there,

I have the same problem. The Hardware is working well with WaveForms.

Data Acquistion Toolbox for Digilent Analog Discovery Hardware has been reinstalled, Matlab R2018a is updated, FTDI Driver is latest version.

daq.getVendors()

-> index ID Operational Comment

1 digilent true Digilent Inc.

daq.getDevices()

-> No data acquisition devices available.

Are there any ideas how to solve this problem?

Best regards

Thomas

Problem solved:

A colleague mentioned to deinstall other FTDI / CH340 USB Drivers (Arduino). After a system reboot the Digilent Discovery 2 was listed in the daq.Devices() in Matlab.
