After upgrading my Inspiron 5748 laptop from Windows 7 to Windows 10, I have 3 entries in the Device Manager listed as "Unknown Device". I've tried deleting them, letting the system "discover" them, & installing the driver(s) but to no avail.

I've attached a synopsis of my system & the error messages. any help would be greatly appreciated.
