USB device not recognized on my laptop but recognized in other pcs/lap

Q: USB device not recognized on my laptop but recognized in other pcs/lap

Hello everyone..
Yesterday my laptop pushed a new Win 10 update, and all went fine, or at least I think so.
But today I see that my Sony WALKMAN - which I used with no problem until now, can't be recognized anymore.

Basically it just shows as (E or Usb Drive E: but when I click it it says "Please insert a disk into E:/" like there is nothing there.

Now the interesting part is.. if I go to Device Manager I see it and clicking on properties etc t says it's working fine.

But if I go to Disk Management, the Drive shows as 14 gb of unallocated space and it's greyed out.

However, if I put it on my brother's laptop, it works perfectly and it can be opened, music moved into it etc - it shows as Healthy - Primary Partition in Disk Management. So it doesn't seem broken...

It's the same on each of the 4 usb ports btw. But, other usb devices (2 phones, 1 tablet) don't have any issue and are detected.

What could have caused this? I tried the basic Disable/Enable in Device Manager and also Uninstall Driver.. It doesn't do anything, it appears back when I replug it in.

No change in Safe Mode and no change after sfc /scannow

If anyone has any idea I'd be happy to try anything to fix this..

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: USB device not recognized on my laptop but recognized in other pcs/lap

This problem is being reported by many forum members with many different USB devices. It seems that Windows 10 Anniversary is having problems properly recognizing certain USB drives and devices. So far, no one has come up with a clear fix for this issue but it sounds like it is clearly related to the Anniversary update. For the record, I did a clean install and have not had any issues but most of the people reporting this problem make reference to updating to Anniversary.

I have a PC which is having a lot of trouble recognizing a USB data acquisition device. Starting from a situation where the PC *does* recognize the device, here is the basic pattern:

1. PC shows device in Device Manager under "Data Acquisition Devices".

2. If the PC is power-cycled via the power plug itself, the device is no longer recognized under Device Manager ("Unknown Device").

3. If the PC is power-cycled via Start Menu --> Turn Off, same results as above, no longer recognized.

4. If the PC is power-cycled via Start Menu --> Restart, no problems, device recognized.

When the device is not recognized, unplugging and replugging the USB cable makes no difference to the situation. In order to correct the issue, I disable and then enable via Device Manager (which also involves a restart).

This pattern is extremely repeatable.

I am working with WinXP SP2, Pentium, 2.8 GHz, 504 MB RAM.

This PC was returned from a customer site - the PC and USB device are used in a machine my company manufactures. Apparently this issue just started happening one day. We want not only to correct the issue, but in fact to understand the root cause and ensure it will not happen again in the future.

Any suggestions would be greatly appreciated - thanks!

A:USB Device Recognized / Not Recognized based on shut-down method

You could try reinstalling the usb drivers.
JohnWill has fix that is worth a try

Johnwill's solution

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

I'm using an Acer Aspire 5100 with Windows XP installed. Due to malware or some other problem, and because I was due, I formatted my hard drive and installed XP. This is the first time I've done so with this laptop. I downloaded and installed drivers that appeared to be missing - my display drivers for my monitor, and for the wireless card.

Problem: I can hear no sound. The only sound that has played is a PC Beep. Windows does not recognize my sound card; the drivers are not installed properly. It seems that I cannot install them.

The PDF containing the list of drivers is here: http://www.acerpanam.com/synapse/forms/acerdrivers.cfm ; scroll down to Aspire 5100.

My sound is not working. Volume Control tells me there is no mixer, and everything dealing with my sound settings is faded out (there are no devices to select), and no options.

Here's my device mananger: http://i31.photobucket.com/albums/c395/-FLCL-/DeviceManager-1.jpg

I have only updated drivers for the BroadCom Adapter and my Monitor/Display.

The driver I should have installed for sound, according to the PDF, is the Realtek Audio Driver v5.10.0.5257. I downloaded this, but cannot install it. Under my device manager, I have 'Audio Codecs' and 'Legacy Audio Drivers', but those don't seem to work. I cannot uninstall them, and windows will not let me override the drivers with my own.

Thanks in advance.

I tried replacing the hard drive on my Inspiron 9300 with a 200G drive.  The administrative computer tools in Windows XP recognized it, but the BIOS showed it as 130G or so.  I finally had to replace the drive with a smaller one.  I had the latest BIOS version.  Is there a BIOS fix that will allow the larger hard drive to be used?

I just rebuilt an old system using Windows 7 Home Premium after using WinXP pro for many years. The primary hard drive is WDC 150 Mg and Win7 is installed and updated to current with SP1. I dropped a second WDC hard drive in, formatted and was going to use it for a 2nd backup unit. Both of these are sata. Both hard drives are recognized by Disk Management but when I select Computer on the start menu ONLY the primary 150 Mg drive is recognized. If I plug in an external drive, both Computer and Disk Management recognizes the external drive. How do I have Win7 recognize my backup WDC drive so I can use it.

Thank you

Had similarities on my pc.

Goto BIOS, there you have 4 options.

Primary Master
Secondary Master

Primary Slave
Secondary Slave

Set it as follows:

Primary Master -----> Main Boot HDD
Secondary Master -----> EMPTY

Primary Slave -----> CD/DVD RAM
Secondary Slave -----> Secondary backup HDD
Hpe it helps!

I have a Fujitsu P1510D, XP Pro w/ SP2. Just received my NU USB2.0 DVD drive. When I first plugged it in it wasn't recognized, a little fiddling and it was... and Nero started to install. I stopped the installation and ran AVG to check for viruses. AVG ran fine, but when it stopped, seems the drive went *poof*. Nero's install screen was still up, but it couldn't find anything.

I've tried plugging it into both of the laptop's USB ports and into the hub, not recognized. Reboots with and without it plugged in. Removed "unknown device" in Dev Manager, plugged back in. Nothing. It doesn't show up as a drive, and each time I plug it back in it says the drive "malfunctioned". Tried going into Administrative Tools/Drive Management, but only the hd is there..

Tried System Restore. Interestingly, in going through the prompts, it said that no changes would be made to Device D:, though that drive letter wasn't there.

I've tried it on another laptop too, it says installing, ready to use, malfunctioning. Does this mean it's completely hosed and I should send it back, or is there something else I can try before I box it back up?


A:Solved: "usb device not recognized" on laptop

The fact that it failed the same way on two systems doesn't bode well for the health of the drive. I'd send it back.

Hello everyone,
i hope you can help me sorting out this issue that is causing me a hard headache at the moment.

I've bought this new Lenovo Z50-70 laptop with windows 8.1 preinstalled on it. Fresh new.

I'm trying to connect via usb a guitar audio interface (Line6 POD HD500) so i installed the drivers via the .exe setup file i downloaded from Line6's site.
The device worked fine on my previous HP pavilion with windows 7.

Now when i completed the installation, i connected it and i had this error:Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.
I used slimdrivers to update all the other drivers, in case it was a conflict causing the error.
I checked via command prompt with command "pnputil -e" and i saw a driver from the vendor of the device listed, so it is installed correctly i think.
I tried all USB ports i have, 3.0 and 2.0 on one side of laptop and 2.0 on other side.

When on device manager, if i click update drivers and choose the "let me pick from a list of device drivers.." i don't see the company name of the device.

i saw that another guy posted a really similar problem on SevenForum and he figured out how to force windows to use the drivers but he didn't post the solution.. Here is the post: Can't get Windows 7 x64 to use the drivers I've installed repeatedly Solved - Windows 7 Help Forums

Hello all. It has been a while since I've needed help but my run of luck has hit an ugly downturn. Moved my computer three weeks ago and had not plugged it all back together till last night. All these years I had used it without a password to log in but a few months back a tech friend expressed horror at this so I started using one. Last night no matter what I did it wouldn't let me log in, saying incorrect password. Today as I messed around again I went through the steps of asking it to reset password (even though I didn't have disc for reset) and realized it does not seem to be recognizing my internal drive. If one of my externals are on they come up but if I turn off externals I get a bubble that says 'No Drive. This feature requires removable media etc.' My drive seems to be running and the Windows logos do appear during boot. My keyboard seems to be functioning to type password, but when I hit F8 while rebooting I get no reaction, so cannot boot to safe mode, just goes right back to log in page. I have had mold/moisture issues in this new house but have had a dehumidifier running since just a few days after computer arrived here. However I do see some evidence of mold or dust in the case, not a lot but some. Not sure what the root of this problem is but I am trying hard not to panic. Any ideas?

A:Internal drive not recognized/password not recognized

Your tech. friend may have mis-understood when you need a password.
If you are at home and only you and you trusted family have access to you computer, there is no need whatsoever for a logon password.
The only time I have ever needed one is when I was using my own laptop on clients site when I was contracting and I would leave it on the desk over lunch.

Then I have to do it again. All the usb devices (usb cam, speakers, usb3 drive, mouse & keyboard, usb2 extender with wifi dongle on it) work. Please help me!

I plugged my external hard drive into a computer at work and it was not recognized. So I tried another computer at work and it still had the problem. Now it happens on my home computer also. I tried it with a flash drive and it also happened. I suspect that the first computer at work did something to cause this.

I have tried rebooting and unplugging my computer with the device attached. Troubleshoot hasn't helped. I tried uninstalling it and updating software/drivers but it doesn't do anything.

Any advice is appreciated.

Here is my problem. Every Mass Storage device I put in the USB slots, came with the message USB not recognized...

It happened yesterday, when I plugged in the external hard disk into back USB slots. Hard disk works at other computer normally. Then I powered on my front USB slots (ther were turned off for couple of monts), put the phone, and it normally showed memory storage. Then I plugged hard disk into front slots, and it came with error. Then I again plugged phone in, but now I get the USB Device not recognizad, which is really weird, cause it worked a minute ago.

I tried every possible solution I googled, uninstalling SMS Bus Controllers, reinstalling chipset drivers and so on.

Weird thing is that Mass Storage devices aren't working on Windows 8 which is on the other partition within the same hard disk.

To mention, that all USB slots have normal power, hard disk is getting the power, phone is charging, Wireless Adapter is also working normally. I really don't know what could be the problem.

Is it possible that this hard disk could somehow insert some wrong data, because he is the source of this plague

Thanks in advance, waiting for suggestions

A:USB Device not recognized

Couple of questions. Does the external hard drive have its own power supply? Have you tried plugging the drive in without the phone charging? You may be drawing too much current from the 5 volt supply in your computer charging a phone and plugging in am external hard drive without a separate power supply.

Hi guys-

I just bought a new mobile phone and tried to connect it to my PC using a USB cable (which came as an accessory with the phone), Windows XP SP3 gave me the following error: "USB Device not recognized". But the phone is charging and I checked Device Manager->Universal Serial Bus Controllers and there were no yellow exclamation marks either.

In total I have 6 physical USB Ports, 4 in the back & 2 in the front. On one of the ports on the back I have my HP Printer connected (the device is in power off mode).

The error message displayed is consistent for the 2 ports in the front, but for 2 out of the 4 ports in the back the phone connects perfectly displaying the internal & external memory in 2 separate drives, as for 1 port in the back it says "High speed usb device attached to non high speed hub"

What is going on??

This has been a problem for some time now, and one by one all of my flash drives seem to be malfunctioning. When I insert the devices into the USB port it comes up with the message on the bottom right side of the screen saying "USB device not recognized" and when I click on it it says to "reconnect the device, if Windows still does not recognize it, then please replace the device".

I have tried various methods on the internet and I have also tried inserting it onto other computers but it seems to be the actual device and not the USB port that is the problem. What annoys me the most is that I was about to make a backup of the data on another flash drive, and I am really hoping I can recover it (about 13 years of photos etc. on there).

It must be the connecter as when I insert the device it vibrates and I can hear the disc (or whatever it is) spin and it even makes the sound on the computer (at least its picking it up) yet when I access My Computer there is nothing there. Intrestingly when I unplug it for a short period of time a folder comes up titled something along the lines of "General drive" (I forget what it is called and will check later when I have it with me). When I click on this it comes up with an error message saying "J: Drive refers to a location that is unavailable.."

I hope this can get fixed eventually,
thanks in advance.

I have an HP Pavilion zv6000 laptop running XP Home and a Toshiba E335 PDA. Up until a few weeks ago I was able to sync the two using Active Sync 4.5. Suddenly, the laptop is not reconizing the pda. I get an error message saying that "one of the devices connected has malfunctioned and Windows does not recognize it." When I click on the annoying bubble I get an unknown device which eventually states that there are no drivers for the device. So reinstalled the drivers and I still get the same error. I've uninstalled the device and tried to reinstall in addition to visiting the Toshiba site and downloading the drivers from there. I can't rollback the drivers because it claims there are no drivers installed. It is extremely frustrating since it worked fine. I'm wondering if a Microsoft update might have screwed up things. Does anyone have any suggestions?

"USB Device not recognized: One of the devices attached to this computer has malfunctioned and Windows does not recognize it."

This happens when I try to connect either of my smartphones (iPhone 4s, Galaxy s3) to my computer. The computer pretends like it's noticed that there's something there, then either chooses to ignore it or informs me that it doesn't recognize it. The phones think they're connected then disconnected then reconnected, ad infinitum. It's not the phones, I can connect them to a different computer with no problems. I can also connect and use a printer with my USB ports, so I don't think it's the ports either. Thus, some computer issue which I am too nooby to fix myself.

I've tried absolutely everything the Internet has to offer with this problem (uninstall USB driver and restart computer with device still attached, for example) but the problem stubbornly persists. Any further ideas about what to do would be fantastic. Thanks

What is the brand and model of the printer. This series of errors is a known, and common problem, with HP officejet and multifunction printers. If it is one of the many bad models, you have no chance of fixing it without replacing the system board of the printer. Easier to buy a new one.
Problem is also common in some Canon and Lexmark multifunction printers.

I just noticed that the USB ports are not working properly.  The mouse/keyboard/printer work correctly but when I plug a camera or memory stick I get a USB device not recognized error.  If I plug my mouse into one of those other USB ports it works correctly.  My guess is that somehow all the USB ports have reverted back to USB 1.1 configuration.  I don't know when the problem occurred,  but I recently installed the latest MSOFT security updates, etc..,  a new version of Norton Internet Security.  When I check BIOS for USB, there is no setting to 'enable hi-speed USB'  that Intel website suggests for chipset 915G.  Any thoughts on how to recover/enable USB 2.0?  Thanks for any suggestions!

A:USB Device Not Recognized

Hi jmg290, just a small hint, maybe won't help but still...I faced exactly the same problem on another system - first my camera was not recognized, few months later I had problems with USB mouse - intermittent problems..Finally I found a capacitor on the motherboard which was almost "blown up". After replacing it, mouse and other USB devices started functioning properly I think it is worth to have a look... Good luck ! Tomi

Every time I plug in any USB device into my Acer Aspire 5100 laptop, I get the dreaded USB device not recognized pop up message. I have been trying for months to fix this, but cannot find any solution.

some info:
Vista home edition 32bit
AMD Turion 64 x2 mobile TL-52
Acer Navarro MOBO, ATI Xpress 200 chipset

I have tried unplugging the computer and letting the battery drain, updating drivers, system restore... nothing helps.

the problem started about a week after I reinstalled windows on my machine after a power outage caused my computer to cease booting at all. I plugged in my new ipod nano, and updated it one time, and then my USB ports never worked again after that first time plugging in my nano. No devices work, no mouses, no printers, no flash drives.

please help! Thank you!

Hi guys!!

I've been meaning to ask some help regarding the issue that I am having however I was reluctant because of the fact that I fix computers for a living(I'm not that good at it though..).

I need help!!

I've been getting "USB device not recognized". I got the issue after purchasing a new power supply. I think my motherboard is fried. But I need your opinion guys. Here are the things that I did.

- went to device manager and uninstalled everything under USB controllers
- dismantled my computer to the very last piece and put everything back after an hour of waiting. (i made sure that the power was drained)
- put back my old power supply thinking that the new PSU that I bought was damaged

When I plug it in, it just says "USB device not recognized". I tried plugging my usb to a different computer and it was not working anymore. I did a little experiment and tried a good USB device on another computer. It worked well, for sure. I plugged it in mine, it said "USB device not recognized". Plugged it back in the computer that detected it earlier and BAM! It won't detect it anymore. Power surge I guess??? I am not sure...

Please Please Please.. I need your help on this guys..

1. Is my motherboard fried?
2. Is there a way for me to fix the devices that I plugged in my computer?

Many Thanks!!!

The only USB port being used is for an optical mouse, which I have replaced and the error keeps occuring. Any ideas?

thanks in advance!

Hmmmmm... Sounds like a call to Dell might be the answer to this one. Un less you have had other things in the past pluged into any of the USB ports then that is the only thing I can think of that would cause that problem or it could be that the computer was part of a net work and reading it from there but that Idea is very far fetched. I would call dell or look on ther site in the FAQ section and see if anyone else has had the same problem. This sounds like a dell thing to me. I could be wrong though Its a thought

I have an issue with the USB ports on my computer. They were working ok and suddenly they started causing problems. When i plug in a device into one of the usb ports it seems as though there is power going into the device but the device is not showing up as working. Even in device manager it appears as though there is nothing plugged in at all as it is saying 'unused port' for all the usb ports. The usb controller are all enabled in bios and windows.
Also, the usb ports are onboard the motherboard along with the network card. When i plug a ethernet cable into the network port a error box appears in the toolbar saying 'usb device not recognized'. I cannot understand the problem and connot resolve it.
I have a feeling i may have had a power surge but not sure the symptoms i am describing would suggest a power surge had caused the problem?
Any help much appreciated...

I'm recieving the following error "USB device not recognized". I have attempted many fix recommendations I have seen posted aroun the internet with no luck. My usb ports were working fine previously with xp and vista installed on my system. I installed windows 7 and they were working fine until the very first update for windows 7 was installed. Since the update I have been unable to use any usb products(printer, iphone, etc...) other than my mouse and keyboard. I have attempted to uninstall the update. I have also attempted to install windows xp, vista, and windows 7 and have had no luck with any version.

I don't know what information I could provide that would assist anyone in helping me. If I need more info posted, please let me know. I would greatly appreciate any help provided.

A:USB device not recognized ???

My USB flash drive is suddenly stop working, when I insert in the slot it detects but it says Windows is not recognized the device and in the device manager it shows Unknown Device. I have tried this USB on many computers and on different operating systems but the problem is same. I think its builtin plug and play driver is corrupted. I have my important data on it and I have to recover it. Please help me!!!!!

A:USB device not recognized

"I have my important data on it and I have to recover it"

Never, ever store important & irreplaceable data on just one drive, and especially if it's a flash drive as they are more prone to failure than hard drives (and unlike hard drives you don't get any warning). Flash drives are designed for short-term storage only (such as transferring files between computers).

It's not a driver issue if the same thing happens on other computers, because the driver is built-in to Windows (Windows XP and later) and they can't all be corrupted. The fact that the fault is constant on all computers proves that it's a faulty flash drive or it's simply worn out and needs replacing. Buy a well-known, reputable brand (Integral, SanDisk etc).

Normally I would recommend using some file recovery software to retrieve the data on it, but that requires the system to recognise the drive.
I can't think of any other way.

This is getting irritating enough I am tempted to go back to XP. Every time I plug in a USB device to charge it, for example my GoPro helmet cam, or just have an empty USB cable plugged in to one of the PC's ports and leave it on my desk so its ready to
plug something else  - I get that P.I.T.A. message popping up every couple of seconds.It won't go away either, it just keeps popping up again and again.
I have the all the latest updates, including the latest service pack. I powered off the CPU by unplugging it for 5 minutes and it still pops up whenever I plug in a cable or a device like one of my pocket video cams just to charge it.
Is there a fix for this or not?

A:USB device not recognized will NOT go away



I really understand how frustrating this is for you.  I would like to assist you to solve this problem.


According the issue, I suggest that you may try to upgrade your BIOS and reinstall the USB controller driver.



Download the driver from the manufacture’s website.


Go to control panel>administrative tools>computer management>device manager.

In device manager, expand the "universal serial bus controllers" tree, and delete things from the bottom first, one by one, going upwards. Root hubs
and then host controllers. Reboot.

Install the driver you download manually.              

If the issue persists, please copy usbstor.inf and usbstor.pnf (c:\windows\inf) from another known Windows 7 computer to problem computer.


Also I want to know some information about the power supply of your machine, for example the voltage your power-supply device, the quantity of your disk and CD-ROM.
If you use several HDDs or CD-ROMs, I suggest that you may try to uninstall some device and try again. Since I suspect this problem is caused by power supply.


In addition, please collect the hardware installation log file in the path of %WINDIR%\... Read more

I just purchased a game controller, specifically a thrustmaster firestorm dual analog 3, and it is supposed to be automatically recognized by windows 98se, as an "HID compliant Game Device" however, nothing happens when i plug it in to one of my computer's usb ports. The LED on the controller lights up when i plug it in, so its getting power, but it is not being recognized. My usb ports are on a pci card, so i'm not totally convinced that they are working, but they show up in the device manager. I'm wondering how I can be sure that my usb ports are functioning correctly, and if they are, what can i do to get my computer to recognize the game controller when i plug it in.

A:usb device not recognized

The easiest way to check them is to find a USB device that you know to be functional and try it on your system.

I have an Inspiron 600M. I have had it about 6 weeks now and for the most part, I love it. About 2 weeks ago, however, I started getting a ?USB Device Not Recognized? message. The problem is there is not a USB device, or any other device, plugged in when it does this. The message comes up and goes away about 5 to 10 times, then it stops for awhile and starts it all over again. Getting to be very annoying. Help.
