Lenovo B50-10 80QR WIN10 USB 3.0 works as USB 2.0

Hi

in my new Lenovo B50-10 80QR I installed WIN10 and after install all available drivers from System Update utility.

The only thing that doesn't work correctly is the one USB 3.0 port where every device attached work but as USB 2.0 port speed. I connected two different 3.0 external hard disks and both go in "white light" as USB 2.0 and not "blue light" as USB 3.0.

I tried with USB Legacy Disable in BIOS and to set off Power management in device management but nothing changed.

 

Someone can help me?

Thank you and bye

Hi parabinho,

 

Thanks for posting and welcome to the forum!

 

Have you attempted to update your unit with the latest BIOS and Chipset drivers from the Lenovo Support page and then retry the steps you previously mentioned? You could also find the relevant drivers in Device Manager, uninstall them, restart Windows then let the drivers automatically reinstall.

 

Hope this helps and let us know how you get on

Ryan,
I had already upgraded the system to the last BIOS and chipset drivers from Lenovo support site.
I tried to disinstall and reinstall USB drivers from WIN10.
The problem happen again.. The extenal USB 3.0 drives (i tried with two different drives) work fine but as USB 2.0.

I wait any other comment or action to do.

Thank you in advance

Hi Paolo,

 

Do you know the speeds you're getting when transfering data using both 3.0 and 2.0? Could you provide some info on the drives you're using?

Ryan

in attachment the data required.

There are two performance runs with CrystalDiskMark for the same external disk Toshiba USB 3.0, one with a Thinkpad T430 through the USB 3.0 port (and blue light on the Toshiba disk controller) and the second one with the Lenovo B50-10 through the USB 3.0 port but that seems to works in USB 2.0 mode (white light on the Toshiba disk controller).

The other file is the driver list with the driverquery /V windows command.

 

Thank you and bye
