Looking for SM bus Controller driver for Prodesk 400 G1 running Windows 7

[bobmdi]

I have an error indication in Device Manager. Under "Other Devices" SM buss Controller has the yellow mark and in the "drivers" tap the driver is "unavailable".  The PC seems to run fine, though the USB 3.O ports only run at 2.0 speed. Maybe that;s related?  I 'm guessing this means a missing or corrupted driver, but I don't know how to identify and find the driver this system requires. The motherboard info is:

Manufacturer Hewlett-Packard
Model 198E (SOCKET 0)
Chipset Vendor Intel
Chipset Model Haswell
Chipset Revision 06
Southbridge Vendor Intel
Southbridge Model H81
Southbridge Revision C1

The OS is Windows 7 pro 64bit SP1 and the PC is an HP ProDesk400 GT Microtower

I can get to the intel driver and support assistant page which correctly identifies this PC, but has the message "No supported drivers or software updates are available for this system". I guess I'm not not looking for an update, I'm looking to install the original(?) driver but I can't seem to locate the link to it. If I don't use the support assistant and go directly to the "Chipset" section,  If offers multiple choices, none of which appear to correspond to what I heed.

Any help in identifying and locating the driver for my system would be much appreciated!

Also, what would the consequences of not having the SM bus Controller driver installed properly be?

Below is the link to the driver you need to install the smbus controller.

sp71260.exe

If you installed the W7 USB 3 drivers, I doubt that installing the driver for the smbus controller will make any difference.

Thank you. That file did fix the SM bus issue. It no longer appears as on "other" device with no driver.

I'm still working on some USB 3 driver issues, but that's another story!

Thanks again
