No it is an actual USB audio device locally connected (USB 2). I am using an older Lenovo X240 for the test.

It is possible you installed this driver using "devcon install"? That would do it, too.  Such a driver would not have any connection to the hardware.

This is an odd one.  The hardware ID is shown as USB\VID_1395&PID_0089&MI_03\7&137947F4&0&0003, and the MI_03 identifiers are created by usbccgp.sys.  It's possible this is a test failure covered by a filter.
