Please excuse me if this is the not the right area to post this question, this is my first post. I have been using my Cary 303T SACD as a DAC to listen to digital music stored on my computer running WIndows Vista. This worked fine till my laptop died, and I ended up with a new Windows 10 laptop. The Cary USB drivers seem to install correctly: install completes without errors, and the Cary Audio USB Driver is listed under control panel - installed programs. But when I plug the laptop to the Cary with the USB: The Cary does not recognize the PC, the display shows: PC/USB D-IN: NONE Windows 10 beeps (so it recognized something was attached) but does not recognize the device, Device Manager displays: Unknown Device, and when I check the driver details for the unknown device it says that No driver files are required or have been loaded for this device. The drivers are the latest ones available from the Cary web site. I tried re-installing this multiple times, with different combinations of installing in Compatibility mode for Windows 7 or Vista, as administrator, etc. I tried the Windows compatibility troubleshooter. I tried disabling driver signature enforcement following this video. I tried disabling USB selective suspend setting following this advice, and forbid WIndows to turn off the device to save power based on this site. The cable is OK (it is the same one I was using previously), but I also tried another one just in case, and tried all the laptop's USB connectors just in case. No luck. Has anyone else run into this ? Any suggestions to solve the issue ? Thanks in advance, Christiaan
