The WD My Passport 2TB will not work with a USB 3.0 Hub. It must be connected directly to the USB 3.0 port to work.
I have 32 External Hard Drives, 16 of them are USB 3.0 drives of 2TB & 3TB capacity made by either Western Digital or Seagate. All of them work through my two different kinds of USB 3.0 hubs without any problems. The only exception to this is my latest acquisition, the Western Digital 2TB My Passport 2 1/2" external hard drive. It seems to only want to work if connected directly to the USB 3.0 ports on my PC using the ridiculously short 12" ish cable. I’ve tried different cables to no avail. I tried powered hub, non-powered hub, still no go. To make matters worse, when I attach this drive to the same hub as my 1TB My Passbook purchased a year ago it drops the 1TB off the hub. Now these are the only things attached to the hub and it has a 2.5 amp switching PSU, which should be plenty of juice to drive two little hard drives.
To me, this drive is a FAIL and it is going back to Costco for an exchange to see if it is a lemon or of this is par for this drive. (Ooooh, bad pun).
