I have a SX38P2 Pro Shuttle PC with Windows 7 RTM installed, and I'm experiencing an odd problem with the onboard IEEE 1394 controller. I don't have any firewire devices attached to the PC (it has one mini-connector on front and a regular size on in the back), but the entry for the host controller itself looks REALLY strange in Device Manager. There are 4 entries for 'IEEE 1394 Controller' showing up under an 'Other devices' node, and 28(!) 'Texas Instruments 1394 OHCI Compliant Host Controller' entries showing up under a 'IEEE 1394 Bus host controllers' node.
If I view by connection, all 32 entries show under Intel(R) 82801 PCI Bridge - 244E. The four 'Other devices' entries all have a status of 'No drivers are installed for this device' and give the location as PCI bus 4, device 28, 29, 30 and 31.
Under resources it says 'This device isn't using any resources because it has a problem' The 28 other entries show with one of 3 errors: Device 0 through 9 show code 12 (This device cannot find enough free resources that it can use) Device 10 shows code 10 (This device cannot start) Device 11-27 show code 31 (This device is not working properly because Windows cannot load the drivers required for this device) All of these 28 show the driver as 'Texas Instruments 1394 OHCI Compliant Host Controller'. Driver provider = Microsoft, Driver date = 6/21/2006, Driver version = 6.1.7600.16385, Digital Signer = Microsoft Windows. Driver details contain one file, 1394ohci.sys.
Windows 7 startup should proceed, but a message box is displayed informing you that the ohci1394 service has failed to start. Restore Default Startup Type for 1394 OHCI Compliant Host Controller (Legacy) Automated Restore. Select your Windows 7 edition and Service Pack, and then click on the Download button below. In this article. Windows 7 includes 1394ohci.sys, a new IEEE 1394 bus driver that supports faster speeds and alternative media as defined in the IEEE-1394b specification. The 1394ohci.sys bus driver is a single (monolithic) device driver, implemented by using the kernel-mode driver framework (KMDF).
This is driving me crazy since everything else on my Win7 installation is working so well. Any clues as what could be wrong and how to fix it would be greatly appreciated, and I will happily supply any additional troubleshooting information. Wow, this is very weird!

Please try uninstalling each of these nodes. When you get the last one uninstalled, reboot your PC. (Normally you don't have to reboot to reinstall drivers, but you're also getting a resource allocation issue. When the PC restarts and all of these devices get reinstalled, hopefully that will resolve this).
Have you installed any other drivers on this machine besides the ones that came with Windows 7? What other software have you installed?Want to know if your hardware will work on Windows 7? Check out these links:.
I uninstalled all 32 instances and rebooted, then let the PC sit for a bit to see if the new hardware wiz would kick off. It hasn't so far, and in Device Manager I now show only one instance, listed under IEEE 1394 Bus host controllers.
It is identified as 'Texas Instruments 1394 OHCI Compliant Host Controller' with a yellow bang. Device status shows a code 10, this device cannot start, and the location is PCI bus 4, device 10, function 0. That location, device 10, was the only one that showed with a Code 10 even when I had all the 32 instances listed.
HW/Compat IDs are the same as before: PCIVEN104C&DEV8023&SUBSYS51061297&REV00 PCIVEN104C&DEV8023&SUBSYS51061297 PCIVEN104C&DEV8023&CC0C0010 PCIVEN104C&DEV8023&CC0C00 PCIVEN104C&DEV8023&REV00 PCIVEN104C&DEV8023 PCIVEN104C&CC0C0010 PCIVEN104C&CC0C00 PCIVEN104C PCICC0C0010 PCICC0C00 It is a pretty clean machine - I did a fresh Win7 RTM install, adding Office 2007 Enterprise, Live Mesh, the Windows Live suite, Skype and the Zune desktop client. Last night, in an attempt to troubleshoot this, I did run the latest Intel's Chipset Device Software (infinst911autol.exe) but it didn't appear to make any difference. The only other potential oddity - and I think this is just my poor understanding of the intricacies of HID - is that I have two entries under keyboards - both named 'HID Keyboard Device', three entries under mice - all named 'HID-compliant mouse', and A LOT of entries under the Human Interface Devices grouping (9 x HID-compliant consumer control device, 2 x HID-compliant device, 4 x USB input device). In terms of actual physical hardware, I have one keyboard, one mouse, a LifeCam, a smart card reader, speakers and a printer. Thanks for looking at this! Please go to c:Windowsinfsetupapi.dev.log.
Go to the bottom of the log, and scroll up. Please copy all of the sections with a timestamp from today and paste them here.
The HID thing having multiple devices is pretty normal. The 'normal' keys appear as one device, and the 'special' keys (like power, calculator or keys that launch apps) appear as one or more nodes. If you view 'by connection' in device manager, you can see which devices are associated with each of those HID instances.Want to know if your hardware will work on Windows 7? Check out these links:.
