I have a new Keithley DQ6510 that I would like to connect to my PC (Windows 11) with the USB interface.

I installed the Keithley I/O Layer program (version C10).

As you can see from the image attached, I see the device in the Windows Device Manager in the folder Other devices, rather than the expected Universal serial bus controllers.

I tried to communicate with the DAQ6510 with the Keithley Communicator and with the Keithley Configuration Panel, but I cannot find the USB instrument.

The PC I have been working on had already installed LabVIEW 2020 and LabVIEW 2023. I cannot see the device also in NI MAX.
Any ideas on how to solve the issue? A fresh install of LabVIEW and Keithley I/O Layer?
Thanks,
Davide

It seems Windows has not properly associated the DAQ as a USBTMC device.
Until that is resolved, all the NI VISA based communications will not succeed.

In Device Manager, can you have it update the driver for the entry?
Or delete that entry and scan for changes.
You need Windows to associate the detected USB device as USB Test and Measurement device.

Sometimes, if a driver is not present when the plug-n-play device is first connected to Windows, Windows will make generic other device association.  With driver installed, need Windows to take a fresh look and make proper associations.

Thank you for the answer. 
After downloading and installing the drivers I found at
https://www.tek.com/en/support/software/driver/keithley-ivi-com-ivi-c-driver-models-dmm6500-and-daq6510
and telling manually Windows to look for the drivers in the Program Files folder, it installed successfully the device.
