Using the function
visadev('TCPIP0::127.0.0.1::inst0::INSTR')
Gives the error
Unable to get VISA installation information from shared library.
And
visadevlist
returns
Unable to find any VISA resources during the specified timeout period. Open the vendor's control software to search for available
VISA resources.

I am also getting this error when connecting to Keysight instruments. It is particularly frustrating because there appears to be no change in the hardware or connectivity setup parameters. I didn't run into this issue using the original 'visa'

Hello,
I had the exact same problem and fixed it as follows:
- Open your Keysight Connection Expert
- In the top right hand corner, click the little gear symbol to open the settings dialogue
- Go to "Tools"
- Got to "VISA Conflict Manager"
- In the tab "General VISA Settings", no implmentations were enabled when I first opened it. I have multiple implementations installed and now enabled "Keysight VISA" and "Keysight VISA.NET". Also, I selected them as the "Preferred Implementation".
- Press "Apply" and "OK"
After this, the
visadev
command worked again for me.

This can be fixed in the vendor's VISA Conflict Manager utility. Refer to https://www.mathworks.com/matlabcentral/answers/1684554-why-do-i-get-an-error-with-visadev-and-visadevlist
