Why there is no data acquisition devices available?

Hello

I´ve been working with USB 1208FS and appears a message, like this

"no data acquisition devices available"

I downloaded the additional software for USB 1208FS, such as:

-Data Acquisition Toolbox Support Package for Measurement Computing Hardware

-Matlab version 2018b

-Data Acquisition Toolbox version: Name: 'Data Acquisition Toolbox' Version: '3.14' Release: '(R2018b)'

-DAQami

-InstaCal

Despite that, I can´t get to measure voltage. Please help me!

I'm looking forward your comments and reply.

Thanks a lot!

What is the output if you enter the following commands into MATLAB? They check for installed drivers for vendors and available devices.

>>daq.getVendors() % you should be able to see Measurement Computing as a vendor if device driver is installed correctly

>>daq.getDevices()

Also, make sure you are able to get voltage reading from the device without MATLAB. Is there any software shipped with the device that allow you to read voltage to computer?
