The VID and PID, etc are not read from the device. On the recently upgraded machine, the soundcard will not enumerate in Windows. Works fine today on a different Windows 10 machine (x86). The U7 had been working on my Windows 7 Pro system for about 15 months without incident. All is well except my external USB soundcard, an ASUS Xonar U7.
I upgraded from Windows 7 Pro 圆4 to Windows 10 Pro 圆4 this week, build 10586.164.
