Appear then Disappearing USB Hub
Posted on 2012-04-05
I bought a USB Hub with power adapter which has multiple ports.
After connecting it to my pc, plugged my USB external hard disk into the USB Hub, the USB drive letter that is linked to the USB external hard disk, appears as drive F then suddenly disappears. WHY is that?
But, if I unplug the USB Hub, then connect my USB external hard disk to the pc, the drive F appears permanently. Further, from computer management, the USB Hub is present under the USB controllers .
I'm running Windows 7.
Appreciate any help.
