After ejecting WD My Passport HDD it comes back again after 1 second

**After ejecting** (using safely remove hardware windows feature) **WD My passport external hard drive** , it comes back again after 1 second (it disappears from my computer and then appears again). This doesn't happen when plugged directly into computer, only when plugged through usb hub. It's Anker USB hub. I have 5 other external hard drives, which work fine with it. Only WD My Passport is giving me this problem. (Laptop, Windows 10)
