PARTIAL FIXED: USB 3.0 External SSD not showing up in Disk Management XHCI

Symptom: Connecting an external USB 3.0 drive, in Windows, does not display in Disk Management. The only thing you see is the device is displayed in connected USB devices.

This happened to me with an Asus Zenbook UX series laptop. Attempts to connect a Samsung T3 drive failed. The drive would not show up in Disk Management, nor in the BIOS. Disabling XHCI in the BIOS allowed the drive to show in Windows 8.1, but this would revert the drive to USB 2.0 which is not what we want.

Re-enabling XHCI in the BIOS allowed for USB 3.0, but again, the Samsung T3 drive was still not displaying.

Solution: The Windows XHCI driver needs to be updated. Go to Device Manager, USB Controllers, then right click the Intel USB 3 XHCI device and select Update Driver Software.

NOTE: Not all External USB 3.0 drives will be compatible with the Windows driver and same goes with the Intel driver. The Samsung T3 works fine with the Windows driver, but another external drive randomly disconnects after copying files.

The driver will update with a Microsoft XHCI driver, and you should be able to see your drive in My Computer as well as Disk Management.
