Symptom

Cause
This issue occurs because the USB audio 2.0 driver (usbaudio2.sys) isn't classified as a generic driver in Windows 10 Version 1703. Therefore, the system assumes that a compatible, nongeneric driver is installed for the device even though the driver is generic.
This issue also causes Windows 10 Version 1703 to postpone the search for other compatible drivers through Windows Update that typically occurs immediately after you install a new device.
Resolution

Download Standard SATA AHCI Controller Drivers Windows 10 All the storage drivers (Hard Disk) connected to your computer require a SATA AHCI Controller Driver. Without these drivers installed in Windows 10, you will start having issues while accessing the drives of your PC. And if the SATA AHCI drivers get corrupted or outdated, then you should update them right away. If you have a PC you can simply re-install the hard drive as a slave when you have finished swapping the controller. I currently don't have a PC and wanted to be able to interface the hard drive to my laptop so I procured a USB 2.0 to IDE / SATA adapter from Amazon for about $20. The adapter ended up working fine, but the power adapter that it came with did not work, so I used an old PC power. 
If installing from scratch, right-click the 'High Definition Audio' controller. If updating the driver, right-click the 'Intel Display Audio' controller. Click 'Update Driver Software.'
