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. 

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
