    Unknown Device - WinXP SP2

    I'm rebuilding a Toshiba Tecra M2 with WinXP SP2 and have all drivers installed except one listed as Unknown Device:

    Location: on Intel(R) 82801DBM LPC Interface Controller.

    Details:
    Device Instance Id: ACPI\SMCF030\4&32D50C2&0

    Any idea what driver I need to clear this up? Let me know what other details I can provide. Thanks!

    What resources does it occupy?

    In case that board has a super-IO chip by SMSC, it might be something like an infrared port controller, a smart card reader or somesuch. The part number of the super-IO chip might also help.

    edit: Ah, it's a notebook. Skip the part number thing

    This device isn't using any resources because it has a problem.

    The SD reader's driver is installed. It may be infrared though, or a few other possibilities on Toshiba's website. Hopefully this link works:

    First link is to the driver for the Intel Chip set you listed

    Next link is Toshiba Infrared Port Driver (but not your specific model listed)

    Googling for SMCF030 seems to indicate it is infrared. I'll post back with results tomorrow at work.

    It was indeed the infrared! Thanks for the clues.

    Now, I got one other unknown device I hope you can help me with. It's for an HP nc6400 laptop. The Device Instance Id is ACP\IFX0102\4&28738126&0, and it is using the following resources:

    I/O Range: 0560 - 056F
    I/O Range: 0570 - 057F
    Memory Range: FED40000 - FED44FFF

    It is located on Intel(R) 82801GBM (ICH7-M) LPC Interface Co...

    It was the Infineon TPM.

    I recently completed a lean re-install of XP Pro on my new HP nc8430 notebook and was wondering the same. Thanks for the info. I have NOT (knowingly) installed drivers for the TPM, Modem, or SD/SC card reader.

    I am wondering how to locate drivers for this device: PCI Simple Communications Controller. Device Instance Id: PCI\VEN_104C&DEV_803D&SUBSYS_30A3103C&REV_00\4&2EC 2339 . It appears in Device Manager under "Other devices".

    Thanks!

    A PCI Simple Communications Controller is usually a modem.

    Next time, do not hijack someone elses thread. Create a new thread for your problem.

    Thanks for your prompt reply. I had wondered about that possibility.

    It seems I got scolded on my very first posting here...not sure if I will be back, but thanks anyway to everyone.

    Please don't mind Sterling. He's a grouch, but he means well. And I don't mind if you hijack any of my threads, especially those over two months old and having to do with some place I don't work at any more In any case I'm here to help.

    I Googled part of the string you posted and it seems to indicate that it is the Texas Instruments Smart Card Controller: http://tinyurl.com/yeveme

    I may be a grouch, but I am also one of the Mods here and we play by the rules or we take the ball and go home.

    If I don't scold you, then one of the other Mods will.

    Tip: PnP devices have a 3-character vendor specific device ID. Some devices within Device Manager are unknown by the yellow symbol exclamation mark. Navigating to the subkey:

    HKLM\SYSTEM\CurrentControlSet\Enum
    HKLM\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1000&DE V_0030&SUBSYS_10101000&REV_07
    HKLM\SYSTEM\CurrentControlSet\Enum\PCI\VEN_1000&DE V_0030&SUBSYS_10101000&REV_07\4&1f7dbc9f&0&38F0

    In the right panel is a key called: DeviceDesc: LSI Logic 1020/1030 Ultra320 SCSI Adapter, and other useful information, such a Vendor ID Device ID.

    VEN_1000&DEV_0030&SUBSYS_10101000&REV_07\4&1f7dbc9 f&0&38F0

    The hexadecimal information of important is consists of four digits each:

    Vendor ID: VEN_1000&DEV_0030&SUBSYS_10101000&REV_07\4&1f7dbc9 f&0&38F0
    Device ID: VEN_1000&DEV_0030&SUBSYS_10101000&REV_07\4&1f7dbc9 f&0&38F0

    The same principle can be used to ascertain an unknown PCI device by searching the PCI Vendor and Device Lists.
