I know from the brochure it says i have a 3 0 USB port but which one is it?I have a Western Digital 1TB USB 3.. As you have found, deleting an installed driver will simply reappear should the device be plugged in again.. This is because Win7 will store all drivers that have been introduced to the system.. 0 port (I had for some reason misremembered which side of the laptop had the 3 0 port and didn't check for blue).

My acer laptop model number is V5-573PG.. 0 drive to my Acer's USB 3 0 port It also works So, for some reason, the WD drive + my Acer = fail.

0 speeds I have tried disabling USB power management in the USB 3 0 Host Controller Utility..
