Today we will talk about an issue of USB devices that many users has encountered.
The symptom is when you connect a USB device to windows7 laptop, system will pop up a message “One of the USB device attached to this computer has malfunctioned, and Windows does not recognize it”.

In addition, you can find an error code 43 in device manager “Windows has stopped this device because it has reported problems. (Code 43)”.

This is a very common error code and the cause may not be determined easily. We provide some general troubleshooting steps, hope it's helpful.

Try the steps below:


1.    Make sure you update to latest BIOS.
2.    Reinstall USB controllers
First, please disconnect all USB devices and then perform the following steps:
a)    Click "Start" button, type “devmgmt.msc” (without quotation marks) in the “Search” bar and press "Enter". Click “Continue” if necessary.
b)    In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
c)    Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".
Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.


3.    If the above steps cannot resolve the problem, try the steps below:
a)    Turned the laptop off, unplugged it.
b)    Pulled out the battery for a few minutes.
c)    Then power on the laptop.

Make sure the USB device is working, try changing to another USB port.

5. Also, you can try in-place upgrade your system or system restore from the Windows Recovery Environment (WinRE)

At boot-up, Hit F8 --> Repair --> System Recovery Options Window --> System Restore.



  • Hello,

    1st of all i'm using Win7 on a hp530 laptop.

    I got a problem with my USB flash drive, and the symptoms are exacly the ones you described.

    Problem is that the cause of the error is (i believe) in the flash drive, because it has worked before, but after my home computer got atacked by a virus the flash drive never worked again,  it doesnt even work on any other computer (i tried my formatted winXP home pc, and a machintosh with unix based SO), i can connect other usb flash drives to my computer and they'll work fine, so i guess teh problem is not on the computer side.

    Main question is, is there any way i can restore the main structure of my pen drive so it can be recognizable again by the operating system?

  • None of these recomendations work for most cases. Just do an internet search and view all of the users having this same problem with laptops and desk top computers.

    Is it a coincidence that so many computers are all having USB failures? Stange that Device Manager always says the USB contollers are working but its the device plugged in that is not recognized and supposedly failed. Okay, but why do the same devices work when plugged into a different computer?

    Clean re-installation of Windows 7 does not fix the problem. Unplugging and taking out the battery also useless.  Sure seems to be an OS problem that simply fails to identify any USB device and then fails to apply the correct driver.  Hundeds of suggestions are on numerous threads addressing this issue but everything appears to be simply shots in the dark without any real definitive answer!

  • I think P O'ed got it right.  All this tinkering in the dark leads to an exorbitant waste of time and in some cases damage to computer systems.  Microsoft should acknowledge the problem and find the solution.

  • just got this tonight. Cant imagine what its like for the guy whos been putting up with this for over a year.

    Right out of the blue my podxt no longer recognised. Tried everything. uninstalling all usb devices/hubs/ports etc. Tried the power down solution. No luck. Tried sys restore, no luck. tried registry repair no luck. MS fix tool no luck. You get the idea. Just from what Ive read around the net in the last 8 hours solid leads me to believe this is a fundamental flaw in the MS OS.


  • Also wasted countless hours trying to fix this. I get the code 43 with a Seagate external drive. From what i read on forums, the problem has been reported since mid-2009 and still, no real solutions from Microsoft.

    And i'm sorry, but the turn it off, unplug and power back is not a solution. What the hell is Microsoft doing on that issue ? Why are'nt manufacturers like Seagate doing anything about it, while their products (supposedly windows 7 compatible) are useless on that system ? Windows 7 has been out for nearly 2 years, anybody about to wake up at Microsoft ?

    At least acknowledge the damn problem so  we'll stop wasting hours trying to understand it !!!

  • Yeah, I have followed the run around and have been given the codes.  Nothing works!! My Iomega  external drive works with our Macbook and our Lenovo laptop  Windows XP, but NOT with our Lenovo desktop Windows 7. My problem is I am trying to get my 104 Gigabytes of Itunes onto the Lenovo with WIndows 7 to a make space on the Macbook. I am P.O'ed also

  • I am having the same code 43 error with trying to hook up my printer....I am so aggrevated...what the devil...I bought this laptop to be up to date...instead i cannot even get my printer hooked up.....where is the help...and why does microsoft 7 charge you if you need real support......

  • I have the same problem, Windows 7 Home Premium, HP desktop A350N, not a laptop.  I am getting the same error message.

  • Make sure the USB device is working, install all latest drivers, firmware and bios, try changing to another USB port...

  • Also, you can try in-place upgrade your system or system restore from the Windows Recovery Environment (WinRE)

    At boot-up, Hit F8 --> Repair --> System Recovery Options Window --> System Restore.

  • i also have the same issue with my W7 ultimate 64 bit can anyone resolved this issue. Thanks

  • i m using windows 7 on compaq presario v3000. Drivers for hp m1005mfp are not been accepted loaded to my computer

  • seems I have joined a club with my iomega hard drive, windows 7 laptop error code 43 nightmare. I too have tried many many tricks to no avail. What is to be done, I am gutted all my photos, all my music  and some important documents hiding on my hard drive....

  • I only have this problem with a USB MIDI Device, that had been working for over 1 year, then bang no longer works, get error 43, have tried every suggestion and process I can find and it no longer works.  I an running win 7 64 bit but like i said it worked before, sure smells like a patch that was made in the last 30 days, or a piece of code that was encountered for the first time as I have seen people that have been fighting this for over a year.  Going to try and see if installing driver as 32 bit, dont know if I even can, but that is last option until MS bellies up with a driver patch seeing as their USB Driver dates back to 6/21/2006 which I think is prior to Win 7 64BIT OS?
