Unknown device in devmgmt

[tumppiw]

What driver am I missing?
Everything is working OK, at least i've found to try, and my internet
search hasn't told me anything..

In devmgmt.msc , under Other devieces, there's one Unknown device
This is what it says under Properties, but they're greek to me..

PCI\VEN_1022&DEV_780B&SUBSYS_84C71043&REV_13
PCI\VEN_1022&DEV_780B&SUBSYS_84C71043
PCI\VEN_1022&DEV_780B&CC_0C0500
PCI\VEN_1022&DEV_780B&CC_0C05

780b FCH SMBus Controller

You'll need the chipset driver for your motherboard. The SMBUS is
part of the Southbridge. The SMBUS reads the config serial PROM
on each DIMM module. It is a relatively low speed I2C bus.

*******

I think the "1043" stands for Asus, but I don't have an
official table to decode the SUBSYS with. In theory, the 84C7 could
be used to figure out what motherboard it is, but I have no web
site to do that with.

If your Asus motherboard is an OEM design, simply look for
a retail equivalent motherboard with the same chipset, go to the
site download section, and you can probably find a chipset
package for it there.

There is a 400MB (yikes!) chipset driver package.

The Asus site also names the motherboard as F1A75-M(CM1740).
So I can also look in there. I don't think this is materially
different. The chipset package is only 200MB in this case,
but that means some OS was severed from the package, making the
package smaller.

http://support.asus.com/Download.aspx?SLanguage=en&m=F1A75-M&p=1&s=41

400MB is a pretty big download, for a driver that might only
be about 10KB or so.

I can try the Asrock site, find another motherboard with A75
FCH and see if there is a chipset driver there. The driver
package here is only 50MB.

"52.35MB AMD all in 1 driver ver:8.86RC2"

Inside the Allin1_Win7-64_Win7_Vista64_Vista(8.86RC2).zip file,
I can find...

SMBUSamd.inf

and the line in there:

%AMD.DeviceDesc0% = AMDSMBus64, PCI\VEN_1022&DEV_780B

The problem I had with something like that the other day,
is my Windows 7 laptop refused to install from the INF file
directly. And I ended up having to use the installer code
to do the installation. On a 32 bit OS, it might have worked
to just right-click the unpacked SMBUSamd.inf and it would
have installed.

The package description calls it a "null driver", so it
really doesn't do anything except make Device Manager
look "pretty".

OK, thanks
I think I'll leave it "lookin un-clean"

(and wouldn't Catalyst 13.4 have this "driver", it's installed)

Catalyst 13.4 provides a driver for the GPU inside your CPU chip.
It does not handle the chipset.

If this is an off-the-shelf CM1740 computer, you would think
Asus would have installed all necessary drivers, inside the
OS shipped on the hard drive. Device Manager should have been
clean when you got the computer (with Windows 8 or whatever).

On some new PCs, you can burn recovery DVDs. And one of the
DVDs may contain the "driver package", which is a collection
of drivers. You may find a copy of the A75 chipset driver
in there. When the driver package is 400MB, that tends to
contain drivers for every chipset AMD ever made (A75 included).

Also, some manufacturers have a "driver updater" software
that can be installed, to clean up or update drivers. I used
that for an MSI product I bought once, then uninstalled the
updater software after the update was finished. So that's another
possible option. Look in the utilities section of the
CM1740 downloads, to see if any driver updater is hiding
in there. Or check the manual that came with the computer,
and read the description of the added software, to see
if such is the case.

In this case, it's still going to download that 400MB file,
so it does not necessarily save on download time. It's still
going to take a while, no matter how the file is downloaded.
These updater softwares, are not clever enough to just snip
out the 100KB or so section needed to get that null driver.

No, it's a homebuilt computer consisting of the following:
ASUS F1A75-M pro m/b (BIOS 2203) , AMD Llano A6-3650 boxed, 4*4096MB
(16GB) KHX1600C9D3/4GX,
Asus Radeon HD7790 DirectCU II OC 1GB,
HDs: 1TB+1.5GB (Samsung HD103UJ, Samsung HD154UI)
Opticals: HL-DT-ST DVDRAM GSA-H60N, ASUS DRW-24B3ST
Some cheap Renesas USB3 port card (leftover from old computer, to add
USB3 ports, as case doesn't have front USB3 ports)
WT KM06 case(3*5.25", 2*3.5" ext, 3*3.5" int), add'l Nexus 80mm case
fan, Antec Basiq430W
OS: Windows 7 HP

Then you can download the 200MB chipset driver. The SMBUS folder
will be inside it.

http://support.asus.com/Download.aspx?SLanguage=en&m=F1A75-M PRO&p=1&s=41

The chipset drivers should have been on the Asus motherboard CD,
which you would find in the box.
