After Anniversary upgrade I couldn't manage to have an USB external device to be recognized (the Device management saw it as RAW) . But, after last nights new "Update for Windows 10 Version 1607 for x64-based Systems (KB3176936)" and "Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3176934)" the USB driver problem was SOLVED at last!! Microsoft had a lot of complaints about non-recognition of external USB drives and fixed it..Next time it would be wise to check everything before presenting an upgrade to Windows 10..

(Windows version 1607 OS build 14393.82)
