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

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


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!

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 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.

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..


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 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?

Not on the 9300s that use EIDE (parallel ATA) drives, no - the limit is 137G in BIOS setup.

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!

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

I have an 8GB sd card i used while traveling and upon trying to get the pictures from it the computer does not recognize the card at all, no prompts, nothing. I have tried it in multiple pcs and macs and no response. My Cannon Rebel XS camera says no images found. However, when I plug it into my brother's Cannon PowerShot it actually recognizes and shows all pictures on the card. Does anyone have any reason why this is happening and how I can recover the pictures? I am not willing to just format to make the card work again, I must have these pictures.

Have you tried leaving the card in the camera and attaching to the computer to d/l the pictures that way. I have an Olympus camera and the pictures will d/l fine with the card left in the camera.

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.

Hello, please let me know if I'm in the wrong place or you need more information. I did read the pinned topics, and I hope I'm able to give a clear enough account of my problems, but by all means let me know if I don't.

I am on an HP Pavilion dv6000, Windows Vista 32-bit. Again, I'll give any other info you need.

A few months ago 3 problems started, probably around the same time. I didn't really take note of it when it started, thinking they were one-offs. Two weeks or so ago I took it into BestBuy and had the GeekSquad there look at it. They vaguely told me that there were 365+ "traces," and that it was multiplying any time the computer is on. (It has not, however, gotten any worse since then, and I've continued using it.) They wanted $200 to fix it and it would take days, they said. I don't have that much money to blow, so I'm prepared to save some files on my uncle's external hard drive and just completely wipe this laptop to factory settings. Hopefully though, someone will be able to help find another solution. The people at the store thought the webcam and shutting off problem were virus-related, but that the freezing was overheating. I think all three are virus-related, and I'll go more into each problem here:

Hi there,
I've recently bought a "Trandscend StoreJet 2.5 Mobile" 160GB USB HDD.
The details of the product can be viewed on the following official link of the product.
Link: http://www.transcendusa.com/Products/ModDetail.asp?ModNo=198&LangNo=0

The problem i am facing is, the drive doesn't get detected.
As described in the manual its a "Plug & Play" device and doesn't need to be formatted.
Also, as i am using Windows XP professional it doesn't require to install any drivers.
I've also checked the Disk Management in the Computer management..but it doesn't show up even in there.
I've noticed that whenever i connect the HDD, it gives very low random beeps.
Sometimes after connecting it shows a bubble at the system tray,"USB device not recognized".
I've read the users manual thoroughly and also tried connecting both ends of the Y-cord USB cable in the computer for extra power..it still doesn't detect it.
When i tried connecting it on my friends' PCs it gets detected immediately and works perfectly.
Also, i don't have any issues connecting other USB devices like 4/8 GB pen drives or my mobile phone on my desktop computer..Kindly help.

System Specifications:
Desktop computer,
RAM: 256MB
OS: WIndows XP
Processor: Intel P4 (1.7GHz)

Thanx & Regards,
Saurabh Patil.

d. If any warnings appear, double click and follow prompts to repair.

3: Reinstall USB controller(s).
a. Type Device Manager in the start orb search field.
b. Click on Device Manager.
c. Expand Universal Serial Bus controllers.
d. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
e. Restart the computer.Windows will automatically install drivers for the controllers. See if this solves issue.

4: Set USB selective suspend to Disabled.
a. Go to Start, type Power Options in the start field and press Enter.

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.

I use a Dymo label printer to print shipping labels for my business. Earlier today, it was working fine. A few hours ago, I went to print a label...and nothing happened. So I checked the printer and it said "offline". In an attempt to try and bring it online, it then gave me the status of "not connected". Then, I uninstalled the printer thinking I could reinstall it and fix all my problems. So now, i've been trying to re-install my printer, but when I go through the steps for the Dymo software and I get to the spot that says, "now plug your printer into the USB port and Windows will complete the install process", I get an error message that says "USB device not recognized. The last USB device you connected to this computer malfunctioned and windows does not recognize it".  Please help! I need to be able to print labels!THanks in advance

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!

For a little while now I have been getting error msgs popping up on my desktop that say "USB Device not Recognized, one of the USB devices connected to this computer has malfunctioned, and Windows does not recognize it. Try reconnecting the device. If Windows still does not recognize it, replace the device."
There is nothing connected to my computer, and this error msg comes up ever 10 sec or so.
When I click on it, it shows 6 usb ports, all used except one that is in bold and says "Unknown USB Device" When I click on it nothing comes up.
Now my USBs are not working correctly, since it will pick up a memory stick that I plug in but will not pick up the wireless mouse that I connect.

This problem started last night when I had my printer cord (via an extension cable) USB, and the wireless mouse connected (plus a DVD in my computer). Everything that was plugged has been connceted before and working.
My system is a Vista-64 bit (faily new)

Any suggestions on how to fix this would be great.

I have a Compaq Presario CQ5306UK Desktop PC with windows 7, which I have had for over a year with no issues. I recently went travelling for 6 months and on my return have this issue. I can't say for certain but I think it was working for a few days on return but it may have been from when I first started using it again so I'm not sure if this is from lack of use for 6 months or what.

Whenever I try to connect USB devices I get the message "USB Device Not Recognized - One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it"

My USB mouse, keyboard and speakers still work fine. But whenever I try to connect my camera, my USB card reader, my Iphone or Ipod (So any other USB device I own) I get this message.

I have tried connecting my camera on a friends PC and this works fine.

Searching on the internet I have tried a few things, I have updated all my drivers, I have tried unplugging my PC for 30 minutes, none of these have any affect.

Another potential solution I have seen is to uninstall all USB devices using device manager and then to unplug for 30 minutes. I am unable to do this one as my mouse and keyboard are USB, and there annoyingly are no PS/2 ports on this computer, so can only get so far down the list before mouse and keyboard stop working.

I really hope someone has some idea how to fix this and it's not a sign that some vital part of my pc is dieing!

Thanks in advanced for any help with thi... Read more

First off i have to say i know VERY little about computers. this morning when i turned my computer on i couldn't get my external hard drive to work . I kept getting the message USB Device not Recognized.....One of the USB devices attached to this computer has malfunctioned and windows does not recognize it. I then unplugged everything from my usb ports and figured out that the only things that would be recognized were the mouse and the keyboard. I have tried the system restore but that has not helped. The Device Manager Just says No drivers are installed for this device even though i have (up until this morning) been useing these devices with no problems for months.

HI, I have a ThinkCentre A51 (8122). 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!

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

I've had an issue that has been driving me nuts for the past few hours. I have a Dell Inspiron 537s tower on which ive done a clean install of Windows 7 x64. Everytime I plug in a USB device it gives me a "usb device not recognized error". I've tried every solution ive found (uninstall all usb ports, unplug computer from outlet, updated the chipset drivers, etc). NOTHING has worked.

If I disable "USB2 Enchanced Controller" (USB 2.0) in device manager, all my usb devices magically begin to work and install, but only at USB 1.1 Speed. This is a big setback for me. The strange thing is though, that my keyboard and mouse work regardless. Only things such as my webcam and external hd are "not recognized" or "malfunctioned". I've even tried Vista x64 and Windows 7 x32.

Does anyone have any ideas???

I have a Lenovo Android phone which after it self-upgraded it's software (customized Android UI) does not get recognized when it's plugged into my Lenovo G50 notebook. When plugged in, Windows gives "USB device not recognized" and the phone cannot be accessed. I've tried different USB ports, cables, uninstall/reinstall the driver, nothing works. I also tried the Win10 hardware troubleshooter feature multiple times to no avail. I'm at a loss how I might resolve this problem - and Lenovo Support forum is of no help.

Leave your device unplugged, access device manager, select "show hidden devices" and see if you can find the old inactive device (greyed-out). Once found, delete it, reboot, plug your updated device back in and see if it is now properly recognized:

The app should have no effect on the phone being recognized by the PC.

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

Hello guys, i recently bought a laptop and bought a mouse, speakers, etc, but suddenly, windows asked to restart, i restarted the laptop and when i turned it back on the Mouse wouldn't work anymore, flash drives won't work either, i did system restore and it wouldn't fix, i had to re-install the OS to get it working again, it did, now i turned off the laptop at night to go to sleep, and when i wake up and turn the laptop on, the usb units won't work again.

I already did going to device manager, uninstall everything under usb and restarted, but nothing happened.

It sounds like the USB devices are going to "sleep" and not turning on again. Turn OFF selective suspend using this, and see if it helps.

Until recently my usb scanner, camera and thumb drives (1,2 and 4GB) worked fine...about two weeks ago I started receiving the error message "USB device found" then "Installing your USB device" followed by "USB device is working properly" and then immediately afterwards the error message "USB device not recognized".

Within Device Manager it shows one controller as "Enhanced" so I'm assuming from what I've read that that means USB 2.0 drivers are installed. I've Googled the error message and followed several how-to's but still to no avail.

SP2 Q - how do I tell if I have it installed...within Add/Remove it shows many updates but nothing that says specifically SP2. I've downloaded SP2 but not sure I should/want to open that can of worms (after reading about program compatibilty problems)....any thoughts/suggestions would be appreciated.

1) None of my USB devices work.
2) Do I have Service Pack 2 installed?

A:USB device not recognized and SP2 Q...

Not absolutely certain, but I believe most older motherboards require Service Pack 2 to enable USB 2 support. The older Socket 939 motherboard I had required SP 2 to enable that support. The P35 chipset motherboard I have now has the support built into the motherboard. Follow this link for instructions on how to determine the service pack you have. If you do not have service pack 2 installed, I strongly suggest you download and install it.

Greetings everybody,

I have a Removable Memory of over 200GB where I saved all my videos and photos plus other stuff. Recently, every time I go to My Computer, either I don't see any G or if there is, then all the items show empty folders. After I pluged and unpluged its USB and power cables, it usually worked. Today, however, I cannot make it work. Everytime, I plug it to the computer, I get a message saying:
"USB device not recognized. One of the USB devices attached to this computer has malfunctioned and windows dows not recognize it. For assistance in solving this problem click this message." I do click the msg but I don't get anywhere.

What do you think the problem could be? I am terrified of the possibility of losing years of photos and videos. This was supposed to work as my backup system!!

Your help is greately appreciatred,

A:USB Device not Recognized

Make sure your external drive is unplugged and go into device manage - scroll down to your usb ports and delete them. Reboot the computer and see if your OS, XP I assume, re-establishes your drivers for them. then plug in your HD and see if you can find your files. Luck Jazz

Hey guys. I'm trying to get my Cowon J3 MP3 player to work with my HP Elitebook 8440p. I know, I know- who uses MP3 players anymore right? Well I love this thing to death- it sounds great and has awesome battery life even after something like 7 years or more.

My problem is when I try to connect it to my Windows 10 laptop I get 'USB device not recognized." I've googled the problem as many ways as I can think to do so, and tried many solutions but nothing seems to work. the device is able to connect in both MTP and MSC mode, but neither will work.

I'm currently traveling, and before I left home I plugged it into my windows 10 desktop and interacted with it via windows media player no problem, so I find it unlikely to be a problem with the player itself. I'd try it on another computer but I'm surrounded by macs... (I did try plugging it into my roommates mac just cuz but no luck there either).

If anyone could suggest something that might get this gem of a legacy device to interact with my laptop I'd be extremely grateful
Thanks for reading!
