I have a Dell Inspiron 3847 with 2 USB 3 ports (that is: supposedly USB 3) and run Win 7 64bit. Recently bought a WD Passport USB 3 HDD. Can read/wirte to device fine but sometimes when I boot up (with HDD connected) get a Win 'error' that a USB 3 device could run faster if connected to an USB 3 port.

 

The Device Manager claims that there are 2 USB 3 ports, but is therte any way to determine the real truth?

USB 3.0 ports are blue ones.WD Passport is USB 3.0.Did you install the drivers from here:

Especially under Chipset - Intel USB 3.0 eXtensible Host Controller Driver?

Thank you for the response

 

Yes, all connections are blue ... on CPU and connector from HDD.

 

Had installed the WD SES Driver software and as stated, HDD is working fine - just the Windows recognition is sometimes suspect.

 

The chipset drivers did not show "Chipset - Intel USB 3.0 eXtensible Host Controller Driver". Analyzed CPU (and added intel chipset).

So you have installed the USB 3.0 driver and was accepted or?Connectors are placed on motherboard.I don`t understand why you are talking about CPU.Does the problem still exist?

Problem is VERY intermittent ... from last updates looks to be a Windows error.

All USB 3 entiries in  Device Mabnager say: This device is working properly.

 

Thus Windows problem.
