Hi All,

 

Very strange problem, has been happening for a while now, my passport is no longer recognisable in my USB 3 ports on my machine, used to work fine, then stopped, suddenly!? Now I can’t see it anywhere when plugged into USB 3, nothing in device manager nor diskpart. Works fine on USB 2 ports and works fine in any other PC i plug into. Has anyone had this trouble before?

 

Thanks,

 

Chris

I had this problem.  The 3.0 USB controller power option was enabled which allowed only 2.0 to work.  I disabled and it allowed  the usb to work with 3.0.  The problem occurred when I upgraded to 8.1.
