Device Manager Error – SM Bus Controller

Product Name: Pavilion p6-2022uk
Operating System: Microsoft Windows 7 Home Premium (64-bit)
Motherboard: H-Cupertino 2-H61-uATX (Cupertino2)

Hi,
Your Computing Net Forum has had a high recommendation on Gizmo’s website and so I hope that you will be able to guide me in a right direction in solving my issue. This is my first post here.
I’m helping a friend to get his Pavilion p6-2022uk desktop PC working again so that he can install his brand new Epson printer via USB.

During the printer installation I found out that 4 out of the existing 6 USB ports on his desktop PC were no longer working and numerous attempts to revive them just did not succeed. The first working USB connects to his keyboard and the second USB to his mouse.

And then we noticed in Device Manager the following error:

SM Bus Controller

Reinstall the drivers for this device (Code 18)

After searching for suitable driver on HP website for HP Pavilion p6-2022uk model.I decided to install HP Driver SP56697.exe
I hope the driver we were attempting to install is the correct one for this PC and Windows 7 version.
It did not fix the problem. As right after the restart we were seeing an exclamation mark error in Device Manager:

Unknown Device
error code 28

hardware IDs
PCI\VEN_8086&DEV;_1C22&SUBSYS;_2ABF103C&REV;_05
PCI\VEN_8086&DEV;_1C22&SUBSYS;_2ABF103C
PCI\VEN_8086&DEV;_1C22&CC;_0C0500
PCI\VEN_8086&DEV;_1C22&CC;_0C05

Can you please shine a light and help us in installation of the correct driver and getting rid off this error.

a, If the automatic installation failed, what would be the correct way to install driver manually?

b, Is there anything else apart from usual switching off of the antivirus software that can block or prevent installation of the correct driver?

I would really welcome any pointers and steps to be taken to resolve this issue.
Many thanks,
Arkeyone

      What was that driver listed as being on HP’s site IE. Bus Controller Driver, etc? Did you also install the chipset drivers for that motherboard? When you chose those drivers, did you get the correct bit version for the OS, 32 vs. 64 bit?

      When you run the driver package from HP, it will unpack them in a folder on your hard drive. You can go into the Device Manager and select to update the driver, then point it to the driver folder that was created. However, the HP driver install is pretty good at figuring things out. I doubt a manual install will do anything that the automatic install didn’t.
