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

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

Hello,

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!

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

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 --------------------------------
REGEDIT4

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

"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"
-------------------------- 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..

Thanks!

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?

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.

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.

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,

While working on my laptop yesterday evening, my mouse & external hdd stopped responding. On ejecting & re-inserting them both started getting this message 'USB Device Not Recognized'.

Now none of my three USB ports are working. Though on cross checking, the devices are working on other machine.

The message is getting flashed repeatedly. Also, observed that my battery got drained while it was switched off throughout the night. Have never faced either of these issues with almost 20months of working with W7 Pro.

Pls assist.

A:USB Device Not Recognized

Welcome Parry,

I'm sorry to hear about your problems your having!

Have you unplugged the power cord/charger and then remove the battery completely with the PC off. Give it a good minute or so then reconnect both and reboot

Also check the device manager for any devices (esp. USB related) that have yellow or red symbols on their icon, when nothing is plugged in the usb ports

additionally if you have media card slots check them since they are merely a usb channel, just like the others. - I'm not too sure if the battery has usb connect, i don't think Ive ever heard of that (you know to sense and adjust the power required)

Many internal wireless network cards run off a usb channel so check and see if you have wireless support (assuming you have a wireless transmitter)

Although there are other possible scenarios, that other members will surely offer in time, from the symptoms you described there is, in my opinion:
almost certainly a hardware issue.
it probably involves 1 of 3 things.
A loose or bad contact (corroded over time) or wire connecting the USB ports to the MOB
A problem with at least one of the rails in the power supply, (may also account for battery issue) [Check power levels in bios setup if possible - although sensors aren't always correct either]
a "burnt-out" USB controller IC, or similar issue with a piece literally soldered on the MOB. [albeit, a worst case scenario]

Hello everyone,

So, two days ago I was rendering a video on an editing program, and a notice came up saying I was out of memory. My external HD was in the computer at the time, because I put clips from there into the videos that I render.

Since then, USB devices that previously worked are working anymore (external HD; printer), besides my mouse. Whenever I plug one into the USB port, it comes up with a yellow triangle with an exclamation mark on the bottom right of my screen saying, "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it."

Does anyone know how I should go about fixing this?

I have a Dell Inspiron E1705 laptop.

I have heard of people with this exact problem. Many of them simply unplug their computer and it is fixed. I have tried doing that, but I feel it may be different, since I have a laptop. I will try taking my battery out and leaving it out overnight (again) and will follow up tomorrow.

I have tried reinstalling drivers, and uninstalling the hubs in device manager as well. When I contacted Dell, they came to the conclusion that I need to reinstall the operating system...
Thanks,

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 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.

Anyhow, the mainboard has 1 PCI slot which has my 56K Motorola modem into it. The modem has a jack for a microphone (which is the only reason I need it, to use my mic).

I haven't used the modem in over 1.5 years since I have cable internet, so I don't know when my the modem became inactive.

Anyhow, when I went to Control Panel -> Systems -> Device Manager, I am told the PCI Communication Device is unknown, so I clicked the remove button (to remove the PCI device, hoping that the next time I reboot, Windows will notice the device and tell me to install it).

When I reboot, windows didnt' recognize it, so how can I get windows to recognize it? I opened up my PC and made sure the modem card is plugged into the slot correctly already.

Thanks in advance.

Well, just a couple days ago, I went to plug in my PSP system to put music on it. I have done this many times in the past, and I do it quite frequently, so I expected it to be like every other time, but, to my surprise, in the lower right of my computer screen, an error message pop'd up reading,

"USB Device Not Recognized
One of the USB devices attached to this computer Has
malfunctioned, and Windows does not recognize it.
For assistance in solving this problem, click this message"

When I click the message, all it shows is my USB ports, with my PSP as a not recognized USB device... What happened? I'm stumped.... Keyboard USB's, and Bluetooth USB's still work, just not the PSP. I've formated, and un-installed and re-installed, and nothing works... >.<

during hp printer installation, whenever i connect printer USB cable, it says "USB device not recognised". how to overcome this problem?

A:usb device not recognized

Go to start/programs/accessories/system tools/ system information/ problem devices check for any problems. If the drivers are not there for the usb, they won't work. you might go to hardware manager, select whatever is missing,and then update the driver.
Have you installed the printer drivers with a cd or downloaded the drivers from the internet? If not, you must install it in order for the printer to work.

Hi,

I am trying my darndest to set up a home network. I finally got done with the main computer last night, and it's working fine with the wireless router - Linksys G Speedbooster, after spending hours on the phone with Link tech support and then the DSL company to get them to see each other.

The problem is now I can't get the older computer to "recognize" the USB wireless adapter I'm plugging in. The computer is an older model HP Brio running XP Pro, and the tech guy from Linksys is telling me that the USB port (there's only 2 on the back of this machine) is too old/slow, and that's why I'm getting the error message in the title of this thread. He said I should contact HP to "update the USB drivers." Is that even possible? Based on what I'm reading, it sounds like I need either a wireless adapter "card" as opposed to the USB type (to avoid the whole USB issue?), or get a new card for the USB to get it to work faster and see the newer stuff I'm plugging in there.

Your thoughts are much appreciated...this is exhausting!

At this point,

Clueless

Hello

If I opened the topic in wrong section, please sorry...

Sorry if bad english. Please read the whole text so you could fully understand what is the point

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

Hi,
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.
Your English is good.

This is staggering! I'm on the phone with Lenovo Canada and am being informed that the USB port on the right side is underpowered as a result of poor motherboard design! The two on the left side get full power, but the one on the right does not. They have informed the mobo manufacturer who is trying to come up with a workaround, but until then printers, wireless mice, etc., may experience the "USB Device not recognized" error warning on the port. My issue is with a Logitech VX Revolution mouse. I really want to get the USB wireless transmitter up out of the way as it's plugged in all the time, but it won't run up there . . . I've got a flawed machine, and Lenovo knows it. What do I do?![edit]: 43 minutes later (I need a speaker-phone!) the problem has been "escalated to level 2 techs" to see if they can reproduce the problem (case number 00060S9).

Unless they replace the motherboard, there is not much else you can do, except use the other 2 USB ports (up to 147 items per port, should be enough for everybody!).

Hi guys, first time on the SevenForums so go easy on me I consider my self pretty savvy when it comes to computers, but this problem made me question myself. Today while I was repairing my friend's virus-infested laptop, I've made a terrible mistake - I used my very own USB flash drive on his laptop. I was a bit too late when I came to realize this, and his laptop could no longer identify my flash drive.

First off, I thought that this might be his computer's problem, but it wasn't. I tried plugging it into my own computer when I get home, and the computer would not recognize it.

For troubleshooting, I did the following.Plugging it into different USB ports on my computer.
Restarting the computer
Plugging it into another computer
Plug a different USB drive.
I've come to a conclusion that only the flash drive that I used to plug into my friend's computer was not working. Of course I did a virus scan after the troubleshooting - it gave me 5 infections from Trojan Generic and 2 from Trojan Downloader.

My first guess is that the viruses made my flash drive went kaput, and that I will need to reformat it. But now the computer could not even recognize the drive.

I will appreciate you guys' help.

Welcome!

Is the drive displayed in Device Manager and/or disk managment?

I recently posted here about a USB problem. The thread is located here: Unkown Device - Usb - Tech Support Forum

Please read my initial post and the responses before you post to this thread.

The solution in that thread worked for a few days until the problem was back all of a sudden. So i uninstalled all USB devices and re installed all under the n7110 drivers in the chipset section. This again worked for a few days until the problem returned. But now, the problem seems to be there no matter what even if I do an entire reinstall of my drivers. Any help?

My problem is can be understood by reading this windows xp article. Im running xp with SP1A. The dll s in question on my PC are not at the recommended version even though I have the SP s installed . Anyone have any ideas? Is it possible to just obtain the latest dll s and copy them to the correct location?

http://support.microsoft.com/default.aspx?scid=kb;en-us;318773&Product=winxp
 

A:usb device not recognized

If you can find the dll's and download them, yes you can replace them.

You will likely need to do it in "safe mode" or access will be denied.

Rename the old ones to dllname.old for safety sake so you can revert if needed.

Hey all,
I'm running win 7 64bit on a P6X58D premium mobo

I just build the computer and had a brand new SSD that i loaded windows onto. now none of my USB stuff will work
mouse/keyboard/thumbdrives/anything
none of them work, but when I plug them in windows detects them and just goes right away and says that they dont work usb device not recognized)

I've tried updating windows, disabling usb in the bios, turning off and unplugging and waiting a few minutes, installing all the drivers I can find for usb, nothing seems to work.

Please let me know if anyone knows whats going on and how I can fix it! thanks!!!!

A:USB Device not recognized

Brand new install of M/board etc

Double check front (& rear) usb peripheral leads/connections. Could be wrong way around or connector misplaced & missing pins.

Did win 7 update all its drivers over the internet - not off your motherboard cd?

Are there any malfunctioned drivers in 'device manager' Try clicking on the very top icon and "scan for hardware changes" one or two drivers may be lurking and not loaded properly at first install.

I honestly dont know what to do. I dislike Apple products generally. And am at a complete loss as to what to do.
Any and all help is appreciated.

If you dont have iTunes installed, the driver to recognize it may be missing, else is the cable or the iPods jack.
