Re: Intel USB 3.0 eXtensible Host Controller driver for 7720 inspiron 17r special edition

Hi Logan,

I apologize for the inconvenience caused. The driver for USB 3.0 is not available as Windows 8 includes native support for USB 3.0.I will recommend you to  re-install chipset drivers:

  • Click on 'Start ‘and right click on 'My Computer'.
  • Click on 'Manage' and click on 'Device Manager'.
  • Expand 'Universal Bus Controller' and right click on each entry named as 'USB Root Hub' and click on 'uninstall'.
  • Once done, restart the system and install Chipset drivers from both the links: 

INTEL Intel Management Engine Interface:
Dell Intel HM77 Chipset:
Card reader:

Steps to install a driver:

  • Click on 'Download File'.
  • Select 'Single-file download' and click on 'Continue'.
  • Click on 'Save' and save the driver on the desktop.
  • Right click on the driver from the desktop and select 'Run as administrator'.
  • Install the driver following the on screen instructions.
  • Restart the system after the installation is done.
Once the chipset drivers are installed, make sure you install all the Windows updates and restart the system.

 Update the BIOS in case the issue is not resolved:

  • Click on the link:
  • Click on 'Download Now'.
  • Select 'Single-file Download' and click on 'Continue'.
  • Click on 'Run' and follow the on screen instructions.

Keep me posted. Please reply for any further questions.

Thanks and Regards,
Vikram M
