I have a samsung laptop, model number NP350E7C-A01US. Every time I insert anything into one of my four USB ports, I get the error: "USB Device not recognized".

You can see the laptop here: https://www.samsung.com/us/support/owners/product/NP350E7C-A01US

    I don't believe they said anything about that. 

    Here is the reliability history: 

    Language packs...just the default I think.

    It might have been SWUpdate, but usually if it fails once, it just gives up. I usually give up too because it takes too long lol.

    It literally won't let me ask the question. When I click on it, it asks me to create a profile. However, no matter how many times I press "Continue", the webpage just sits there. I've refreshed the page like 30 times.  The cancel button works but not the continue button.

    I actually don't have a "Write-Caching" option. 

    And yes I did use that tool. Here is what I see:

    Here is a link to the file in OneDrive: https://onedrive.live.com/redir?resid=C8ED24747F2675B2!160&authkey=!AG9UHAo-EeG3os0&ithint=file%2c.log

    I haven't gotten around to creating a new partition yet so I'll have to hold off on that last step.

    Does it make any difference to your problem if you uninstall (via Deview) the device that you have highlighted?

    Sounds good. You can make it on an external drive too. You should be fine without the backup but you had so many issue I don't want to stir something up and not be able to easily go back.

    Are you able to perform a refresh?

    Does the USB program you have contain the ability to monitor USB traffic?

    This may be usefull, http://msdn.microsoft.com/en-us/library/windows/hardware/hh451296(v=vs.85).aspx If you can watch the data from that port you can see what it does and doesn't do.

    I already have an profile with TechNet from some other stuff and I never posted to there so I assumed since it auto logged me in they used the same profile. But I guess not :)

    I am still waiting for a response

    I looked at the WU and CBS logs haven't found anything exciting. When did you fix the task scheduler? It looks like it went out on 7/13/2014 because there was a huge spike in Windows Update Errors. It looks like it couldn't figure out if it was allowed to do an update while on battery power had issues with an internet connection and it paused on 28 updates that ended up failing because it couldn't set a property. 

    What is SWUpdate? Is that a Samsung updater? It looks like something is manually trying to update but the items being updated don't need it. The last ones I say were You may want to disable it to see if things improve on your computer. There is a good chance that it keeps updating things with drivers that don't work. Windows update doesn't always download the newest driver because it only uses ones that are best for you computer. So if knows of an issue or isn't sure it will work then it will reject it

    I don't know why I didn't suggest this earlier but try cleaning the port out. IT seems like it is getting power but it can't send data correctly. It could just be a lose connection on the mother board or something, When you plug in a device does it tell you how much power it requires in the power tab in Device Manager

    You could create a driver.log to see if it is trying to install a driver but failing, however I don't think it is even getting that far
