I've read a number of other users' problems with USB 3.0 not working, but mine is different!
I have an ASUS CM6870-us012s desktop, currently running Windows 8.1 (originally downloaded from the Store, but I recently purchased a retail full-install version to see if I could correct the many problems). It has several USB 2.0 and USB 3.0 ports in front - the USB 2.0 ports work fine, but the USB 3.0 ports SORT OF WORK (but they don't).....
When I plug in a USB 3.0 external drive (Western Digital My Passport), I hear the brief music indicating Plug-n-Play connection occurred (the USB 3.0 end was inserted into the USB 3.0 port). However, I don't get a drive letter assigned, nor do I see it in File Explorer, nor do I see it registered in ASUS's AI Suite II/System Information/Disk......but I DO see it in Disk Management (without a drive letter - just Disk 5)!
There are no problems appearing in Device Manager, nor in any item related to USB (none anywhere, nadda, zip, zero) - everthing is working, so when I look for hardware errors (running Hardware Troubleshooter), none are found. When I look at AI Suite II software to un-install Boost 3.0, there is no Boost 3.0 shown that I can disable or un-install, as others have done to correct their problems.
I tried a full install of Windows 8.1 and have the exact same result, yet when the system was originally running Windows 8.0 (that came on the PC), everything worked perfectly!
Any suggestions would be greatly appreciated!
