This may be an odd issue, but I have a Labwindows application that runs with the cDAQ-9174 over USB. It works on a 2 year old Dell Inspiron laptop (Windows 10) and a Dell OptiPlex desktop (also Windows 10). But it does not work on a new Lenovo Thinkpad T480 (Windows 10). If I run NI MAX on the T480 it self tests OK. But when I run the Labwindows application on the Thinkpad T480 it executes function DAQmxCreateAIVoltageChan without errors but generates an error when it reaches the DAQmxCfgSampClkTiming (error = Specified operation cannot be performed when there are no devices in the task).
Again the Labwindows application runs with NO errors on the older dell computers.
Any ideas?
