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

    Funny now I can't do it. Ill have to look around and see how I did it before.

    What was the power total power available and power used in the USB hub. It might only list both if the hub is in use,

    Daemon tools could cause that. I would try updating it. If you don't need it go ahead and uninstall it. You can always install it if you need it. And it could be causing the error. After you uninstall restart then update the USB Drivers.

    Make sure windows update is set to get updates for all products then run an update check and install all the current ones if you don't have them and the optional ones. Of course you can ignore the programs like bing bar if you want

    Check you startup programs in task manager and see if there are any programs that start that don't need too.

    It looks like there is a USB failure because a driver fails to load. It says ROOT\SYSTEM\0004

    Do you have anything in c:\windows\system\0004 ? Drivers are usually stored in c:\windows\system32\drivers so that is interesting but I am not an expert on that subject so that could be normal

    EDITed-- HA HA! That is a Daemon tools driver. I am an idiot. Guess posting something makes me smarter for a few seconds.

    Still looking around let me know the answers to those questions and I will get back to you when I figure more out.

    The first error

    Log Name:      System

    Source:        Service Control Manager

    Date:          7/16/2014 1:11:06 AM

    Event ID:      7000

    Task Category: None

    Level:         Error

    Keywords:      Classic

    This is an older version of windows but maybe it will help

    If you go into all of the USB devices in device manager can you go to the power management and turn off the option to allow the computer to disable the device.

    Also in the device manager do you see more USB hubs if you go to View > show hidden devices?

    Get a screen shot of before and after I am curious if a USB is turned off for some reasaon

    And Here is a more deatailed troubleshooting method let me know if you need help with it

    Our computers must have some sort of cybernetic link. My computer must have informed your computer about its situation and now your computer must want to join in. Technology is a blast!

    The total power avavilable was 500 mA per port.

    I think i'll just uninstall Daemon tools, I can do the same thing it does with winrar...sort of lol.

    Actually, yesterday I changed it so windows update gets updates for all my products.

    I have absolutely nothing in that folder except another folder called "Speech" with 3 XML files inside, very werid.

    Haha, way ahead of you. I unchecked that option yesterday when researching this issue. No effect unforunately. 

    I'm not completely sure what you mean by a before and after. Do you mean before I click on show hidden devices and then after I click on it? Or before i plug it in screenshot, and then screenshot after?

    I'll do the 2nd option I listed.

    Before:

    After: 

    Also, here is something random that I just saw, I don't have the slightest clue what this is:

    You know what, I think I'm going to let you in on another problem I can't seem to fix while you are here. This program USED to work perfectly, but then I stopped using it. But now, ever since like 4 months ago, it literally won't run. It crashes every time, but it never used to. I can't figure out why. First it says there is a .dll missing, so I get the dll and put it places and etc. Then it gives me some error, something about an endpoint and in a dynamic library. i might have a screenshot, let me see....I can't seem to find it, but I found another error:

    Yeah I know I did it before because it listed every instance of that error. The Speech is a MS thing not sure what.

    I added some stuff on to the last post. Double check you may have missed it because I just did it.

    Also,

    This error could be the issue we need to fix the USB.  

    Log Name:      System

    Here is the older article about it http://support.microsoft.com/kb/899965/en-us This also points to a registry issue which would fit the other issues.

    I would follow that article to see if the regedit they have works for yours but make sure you can reverse it since it was for XP. There maybe an article for 8 somewhere. Just haven't found it

    You may want to post that error in a new thread to see if someone can give you an exact fix. I would post it here too, http://social.technet.microsoft.com/Forums/en-US/home They are the systems experts. That is all the do.
