WD My Passport Ultra is not showing anywhere

It is the second time I am posting this
I am using win 8.1
My Passport Ultra is not showing up anywhere. Not in device manager nor my computer.
It shows up on other devices though and works perfectly fine. Help!
note: the little led thing is lit and the USB port is not faulty. I am pretty sure it is a software problem.

Hi,

Is your My Passport connected directly to the USB port in computer and did you try connecting it to another USB port?

Also, try using a different USB cable or a different computer for testing purpose.
