Unknown Device - on PCI Bus - ACPI\SMO8800 / ~SMO8800 - IRQ 0x00000017 (23)

do you have Win 10 Driver Link to download the driver for the same issue....

The drivers works like a charm under Win10, used the latest link to the driver.

Thank you so much! I've been working on this for 2 days now. The original problem was that I couldn't format my SD cards though it can be read by the slot. I tried diskpart, minitool partition wizard as well as chkflsh. It always says it was on read-only on on minitool and diskpart says it isn't. I stopped working on it and focused on my other problem is was the bang on the device manager, have tried updating drivers, no go until I came about your link and it not only removed the bang but also let me format my SD cards!!! I didn't know that the problems were connected all along! Thank so much!

Thanks - this worked perfectly on my M6600, Win 10 Pro x64. Finally a clean Device Manager!

How does one go about installing it?  Just click the.exe once it's dl'd? Does any/everything else need to be closed?

I just don't want to mess anything else up.  I have an L502X and the switch to Win10 is (STILL) killing me.  I didn't realize it but apparently the driver had an issue Sep 16 last year and I just saw it, so I am trying to remedy it (when I click on "FreeFall Protection" explorer pops-up with "application not found")..

I still haven't found a fix for my Waves MaxxAudio or Creative SoundBlaster X-Fi programs/apps to work right and I gave up waiting for Dell to issue any driver(s) for the "Dell Stage", it's sad.

I used for Dell Latitude E6510 and had a good result, thanks .

Thanks, worked for Latitude E6220 after updated to Windows Version 10.0.15063 Build 15063.

Getting Error while intalling this file, for L E6420

First class solution on Dell Vostro 3560 after reinstallation Windows 10

Worked for a vostro using Windows 10 Pro

Thanks!!

I have installed an SSD on my E6320.  How will this driver (or lack thereof) affect the operation of an SSD drive?  Should I just disable it in Device Manager?

Thanks in advance.
