My Windows 10 device manager states the my Renesas USB 3.0 eXtensible Host Controller is working properly. I have 2 new (1 Seagate and 1 Western Digital), just out of the box USB 3.0 external drives. I have a front and rear USB 3.0 ports. If the device controller is working properly why won't Windows 10 see them? I am afraid if I delete the drivers I may not be able to get them back. I am looking for suggestions. Windows 10 recognizes my 2 internal drives with no problem. Windows 10 has been a bit of a learning curve. Recognizing the USB 3.0 drives is the only exception to my experience thus far. Any suggestions would be greatly appreciated.
