ENVY of HP dv7 Notebook PC: USB-error if HI USB Controller 31 on Windows 8.1 for the HP ENVY laptop PC

My computer has been contiually gel and very slow on all programs.  It seems that it is a USB - IF HI USB COntroller with error 31.  I have all sorts of problems ever since I downloaded to 8.1 with the gel and the slow sometimes, but it has gottne so badly at that time that the computer is sometimes unnecessary.

Hi @wyndeway,

Thank you for your request!

I understand that your computer has been constantly icy and very slow. When you have verified the device displays error 31 on a USB controller Manager.  It started after the Windows 8.1 classification.  To help you more effectively, I need the Envy DV7 specific model do you have? Computers laptops HP - how can I find my model number, serial number or product?.

Do you have a rear roll of 10 Windows to Windows or did you reinstall from a retail copy or perform a recovery?  Have you done all your Windows updates, after the downgrade?  You ran the HP Support Assistant?

Try this for USB:

  • Go to the Device Manager
  • Right click on the USB controller with the error
  • Choose uninstall and remove.
  • Restart your computer.
  • Open the Device Manager and click on Action
  • Click scan for hardware changes.

Please let me know the results.
