USB 3.0 Port is Connecting at 2.0

HP Recommended

HP 8540w

Win 7 x64

Latest Renesas firmware and drivers (sp54511, sp54705) installed

 

I plug in my LG Bl-Ray writer (BE14NU40) and it reports that the port is running at 2.0 not 3.0.

 

How do I fix this?

 

Thanks for the help,

Greg

Are you plugging the writer's usb connector to a usb port with the SS (usb 3.0) on on the right hand side of your mobile workstation?

 

The usb ports on the left hand side are usb 2.0

Yes.  The SS ports are on the right side of my laptop.

Verify the transfer bandwidth with another device such as a USB 3.0 flashdrive. Open two seperate explorer windows. One opened to the usb flashdrive and the other to the folder where you are transferring data to.

The previous troubleshooting scenario suggestion is made in order to isolate the issue to either the usb 3.0 port or the device.

Morning,

 Another thing you can check is to make sure that the device you are using is USB 3 and that you are using USB 3 cables

The device (LG Blu-Ray writer) is USB 3.0 certified as is the cable.  When I plug it in I receive the notification windown saying that the device will run faster if I plug it into a USB 3.0 port.

 

And, yes, the port into which it is plugged (my fifth grade English teacher would be happy with that phrasing) is a blue, SS-marked port.

 

I believe I have a USB 3.0 flash drive by Corsair in my briefcase.  I'll test with it.  Otherwise, I'll have to brave the Black Friday shoppers and go out to get one.

Thinking about this could it be that the main USB host controller is not loading the XHCI driver when a USB device is detected.

 

you could try updating the chipset (sp48432.exe) before getting squashed by the black friday shoppers

I'm already running sp48432 but will reload just to be safe.  Is there a way to check for the presence of the XHCI driver in Device Manager?

I believe the Root Hub is where you look, if you have a look in the device manager, find the Root Hub (there are probably more than 1) and go to the properties, then click on Advnaced it will tell you what speed the hub is running at. USB2 is High Speed and USB 3 is Super Speed

1. I plugged a Corsair 32GB USB 3.0 stick into the SS port and it loaded fine. I didn't get the Windows message saying to plug into a USB 3 port so I believe it is running at Super Speed.

2. In Device Mangler (!) I see two USB Root Hubs which are tied to Intel Series/3400 Enhanced Host Controllers (running at High Speed) and then my Renesas USB 3.0 Root Hub. The Renesas does not have an Advanced tab in Properties but it is running the nusb3hub.sys driver. 

 

One thing I wonder is it shows the Location as 0 where the other USB Root Hubs show their locations tied into the controller.  Shouldn't its location tie into the Renesas  USB 3.0 Host Controller?

 

Thanks for all of the help.
