USB Device Not Recognized - Caused by iTunes Update???

I have been reviewing the posts associated with USB Device Not Recognized and many persons have had this problem, but most are within the past 10-12 days. My problem started after installing an iTunes update.
Can Apple please advise if the latest iTunes update interacts with Windows to cause this problem (which remains even after iTunes is uninstalled).

Check if any of the tips in this thread can help you.

My 6th generation nano isn't recognized by my computer. When I plug it in an error message pops up, which says "USB Device Not Recognized". Does anyone know how to start trouble shooting this. I updated both windows and iTunes.

Work through all the suggestions in this Apple support document first.

TS1369 Hello! I have an Ipod Shuffle 2nd Generation and it is not recognized by my Windows 8 based laptop. An error message of 'USB device not recognized' is shown. I have the latest ITunes version installed, and tested the dock in other pc's.

Hello!
I have a problem connecting my Ipod Shuffle 2nd generation to my Windows 8 based laptop. The computer doesn't recognize the Ipod and issues an error message saying 'USB device not recognized'. I tried uninstaling ITunes(latest version) and all other Apple software and reinstaling it back again, checked my USB hubs in the 'Device Manager' section of the Control Panel, you name it.
I could really use some help solving this.
I've turned to the troubleshooting section in Apple Support but it has nothing concerning situations in wich the device isn't even shown in the 'My Computer' folder.
Help a brother out, will you???

Found a solution in another forum http://en.kioskea.net/forum/affich-63733-ipod-not-detected-on-computer (a few posts down).
It was for an IPOD so you can see those details in the link.
Found how to reset a shuffle and inserted it into these instructions - did not have to follow his last steps.
- Turn off computer.
- Plug Shuffle into usb.
- Then you must reset your shuffle
To reset iPod shuffle:
Disconnect iPod shuffle from the computer (if connected).
Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible

- Start computer and it should install the usb driver for the ipod automatically.
- Your i pod will say do not unplug so don't. then open itunes and it will be there.
I did not have to do these thing below – did not get error message and shuffle was displayed in Itunes. / LMc
Just remember to not only eject ipod from itunes but stop usb.
Go to the program icons near the clock and right click the usb icon and "safely remove hardware" will appear and click it.
Stop it and select "apple ipod".

HP G60-630US Notebook - Webcam is unknown device + USB device not recognized pop ups [update]

My webcam and everything was working fine last night. I even used my webcam on the new yahoo I had installed a few days before. When I got up this morning and turned on my laptop, I kept getting pop ups every 3 minutes stating USB device not recognized despite not having anything plugged. I check out device manager and see an unknown device and Imaging Devices missing. When I try to go into youcam, it tells me that the cam isn't detected.
My laptop is HP G60-630US Notebook PC, Windows 7 Home Premium 64 Bit.
There were no changes made last night. Although after all this I tried removing all of the usb and rebooting, but nothing worked. I am still getting the frequent pop ups. PLEASE any help would be appreciated.
Update: I just ran the Bios update and instead of unknown device, it says USB composite device
This question was solved.
View Solution.

Try this
Use device manager to manually install the webcam driver, Open Device Manager, right click on the unknown image device and select "Update Driver" then "Browse my computer for driver software", then "let me pick from a list of device drivers on my computer" then click the "Have Disk" button, then click the "browse" button, browse to "C:\Windows\inf" folder and find "usbvideo.inf" and select it , then hit OK, drivers should load.

My ipad is not connecting the computer when i plug in, USB device not recognized pops up. I uninstalled and reinstalled itunes without any improvement.

I cannot get my ipad to sync with the computer, the message USB device not recognized keeps popping up. I've uninstalled and reinstalled itunes without an improvement.

Do you have firewall or anti-virus software running? If you do, it helps to turn it off. Otherwise, click on this link and see if it helps: http://www.apple.com/support/ipad/assistant/itunes/

USB device not recognized with 160G ipod

I did absolutely nothing different, no updates, no hardware upgrades, didn't drop my ipod, suddenly when I plug my 160g classic into my computer vista just says "usb device not recognized" and I cant do anything. I can charge my ipod on my radio dock but that's it. I've tried plugging it into 2 32bit vista desktops, 1 32bit vista laptop, 1 XP laptop, and 1 64bit vista laptop and they all give me the same message. I've tried many different usb ports, and 2 different cables, nothing works. Help please!

I don't know if this will help you, but I was having the same problem and when I sent it off for repair...they sent it back saying it was not under warranty b/c it had liquid damage, etc...bunch of BS! Anyway, I called tech support to do a little venting and the technician said i should try uninstalling itunes, Apple updates, and quicktime which will not mess up your library, etc. Restart and then download newest version of itunes from apple website which i did. I restarted again and then connected IPOD 160G to it and to his credit...Ipod started to connect and be recognized in itunes. I had to restart one more time w/ ipod connected so it would all sync, but bottom line...it worked. Apparently, the itunes/quicktime updates can screw w/ these new ipods causing problems. Why they just don't come out and say that or at least suggest this line of solution when they send an ipod back unrepaired...i don't know....very poor cust service on that end of it. Hope that helps.

Windows won't recognize my iPod - USB device not recognized

This is really frustrating. So I got a 4gb iPod nano on Saturday, took it home, set it up and everything was going just fine, no worry's. About 4 hours later I went to adjust my songs and it would not come up in iTunes. A little pop-up box said that the "USB device not recognized - one of the USB devices attached to this computer has malfunctioned and windows does not recognize it." After owning my iPod for less than an afternoon, I now have an ipod that I can do nothing to including change the music, charge it, etc. It works normally otherwise, it just won't connect to my computer. I then plugged in my older 256mb usb stick, and the same message, it too does not get recognized by windows. So I then tried a brand new 1gb usb stick that I had and the same result, not recognized by windows. I updated my itunes to the latest one after purchasing my ipod (version 7.4.3.1) and have looked up everything that I can and tried everything I saw to try, but nothing, absolutely nothing, worked. However my usb mouse, usb joystick, and usb printer all still work, but my moniter that has four usb outlets on it causes the same message, if I plug in the cable that connects one usb on my computer to the four on my moniter, windows can not recognize it. When I look in my device manager at the "unknown device" under the usb controller list it says that there is not driver for it, however I know that the drivers are either on my computer or built into windows. Any help? Anybody have an idea about what to do? Is it something in my windows registry has changed because of the new itunes, etc.?

Now that I've had some sleep, I realise I didn't really provide information that may lead to some specific help. Here goes - when I first plugged in the ipod nano (8gb), It displayed the screen it was supposed to - I could see the lightning bolt through the battery icon and knew it was charging. The icon for the ipod also appeared in the left-hand listing in itunes (in the section that existed under Library, before the sections Store and Playlists). This section now does not appear (I can't remember the title of this section, but it might have been 'devices'). In fact, I'm pretty sure this problem started when I clicked on this icon - nothing happened and it disappeared - so did the display on the ipod, which is not just the apple. This means itunes has only Library, Store and Playlist in the left-hand colunm. While I accept that computers do not work on normal logic, this seems to me to indicate that the drivers are fine, the system is fine, my laptop is fine - its the ipod or the usb cord. This morning as I tried again, this time my laptop gave me the option to 'click on the balloon to solve the problem' - let me quote: "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it. Try reconnecting the device. If Windows still does not recognise it, replace the device". Come on folks - one of you will surely know how to fix this (short of me taking the ipod back to the store to get my money back).

USB device not recognized for iphone

My iphone 4S had an issue and was sent away for repair and in the end it was replaced. I backed all my Apps up to ITunes before sending it away.
I tried plugging my new Iphone into my laptop and it comes up with the error "USB device not recognized", although it worked fine before I sent the phone away.
I went to my device manager and found the device, however it says Unknown device and when I try to update it is says that this is the most up to date version.
I uninstalled ITunes and reinstalled it which made no difference. ITunes also does not find the phone.
I also removed all the Apple programs on my laptop and then tried to connect the phone again but this made no difference.
I have restarted the laptop and this also made no difference.
I called the Apple help line and they can not work it out and suggest I take the phone back to the shop to be checked.
Does anyone have any other suggestions?

DId you uninstall iTunes and all it's components? Or just the iTunes program? Apple Mobile Device would be the main cause more than likely. So it is important whether you uninstalled all the programs or just iTunes. If so what I would try next is putting the device into recovery mode and seeing if it detects it like that.

"USB Device Not Recognized" Bubble/ Ipod won't connect to Windows

Whenever i connect my ipod to my computer the ipod goes to "do not disconnect" and a bubble pops up on my computer saying "USB DEvice Not Recognized" i have switched it to all of my usb ports and unplugged all usbs except for my mouse at the same time. this happens 95% of the time. my ipod does charge while connected and it has only connected to itunes once in the past 2 weeks. im not sure if it is itunes because it started around the time i updated to itunes 7. since it is a windows bubble though i think it is a windows or ipod problem and not itunes. i have a dell that isnt great but works fine.
thanks for any help.
... Go TTU!

Make that two idiots. My roommate got a Sansa and I decided to try out the cable. Nothing happened. Now suddenly my nano isn't recognized by my computer. I'm glad I read your post, now I can stop looking high and low for a solution. Until this happened it worked good as new.

"USB device not recognized" when ipod plugged in???

(ipod mini 4gb)
When I plug my ipod into my laptop I get the message: "USB device not recognized." It says the device has malfunctioned!!! If I click on this error message it says my ipod is an unknown device and no drivers are installed for it???
It was working fine until a few days ago. If i reset it I can charge it up but that's all, it still does not appear in itunes or on my computer.
I've tried eveything on the help website but nothing works! Can anyone help?!
patriot 3050 Windows XP

ok my question is do you have a mac or windows based laptop
here is why and what happened to my ipod mini
my ipod mini was connected to my macintosh charging while i was using my imac and it came up with a system update 10.4.3 i installed it and finished installing it and afterwards my apple wouldn't recongnize my ipod mini or even display it one the screen i found out by myself that when the apple update got to the end of the update it installed new hard drive drivers but also installed the drivers on the ipod mini which locked out the mini's internal hard drive and my mini then stop responding it would play music and charge but wouldn't connect to the computer
so what i did to fix it was this
i went into utilites in mac os x tiger or any version of os x has this and selected disk utility you will notice that the ipod will appesr in disk utility but not on the desktop this is due to a recent system update driver that isn't compatible with the internal drive on the ipod mini so in disk utility just select format the drive in a mac os partition standard works the best it will then format the ipod and the ipod will apear in the desktop again but not as a ipod let me explain when you format the ipod using the disk utility it formats and even erases the firmware of of the hard drive on the mini so when you are done formating the ipod run the ipod updater to reinstall the ipod's operating system and presto your ipod will now work again
warning: i don't know how to fix this on a ipod in windows so if this is a windows based laptop you need to find someone witha macintosh to do this with sorry

Usb device not recognized on shuffle

i have a belkin usb 2.0 device with 2 ports. it is plugged into my ibm thinkpad laptop. the mouse works fine in both ports -as does a photo scanner. but for some reason, the ipod shuffle is not recognized - i keep getting a green blinking lite and a message that says "usb device not recognized". funny, because the shuffle worked fine the other week when i installed all the software after purchase. i've updated windows software and reset the ipod. i've read elsewhere that some people have had the same problem - and that it was a malfunctioning usb port on the ipod shuffle. if so, what a piece of junk. maybe i just need to call tech support and ask for a new shuffle - i don't think that downloading the updater, etc. will help. any suggestions? thanks.

If it's working with other computers (using the same USB cable to connect the shuffle), then the problem is probably related to your computer.
If you connect something else to the same USB port (like a USB flash drive if you have one), does it work?
If you are using a USB hub to connect the shuffle, be sure to try a port that is directly on the computer. And try more than one port that is on the computer.
Also, it may be helpful to know some other details, such as type of computer (Windows or Mac) and the version of OS.
Since this is a laptop, if it has a main battery that can be removed, you may want to try disconnecting it from power and removing the battery. Leave it that way for a new minutes. Then, put the battery back, start it up, run iTunes first, and try the shuffle again. If there was a problem with your USB ports, that may correct it.

Computer says usb/device not recognized when plugged in??

When I plug in my sons ipod nano 7th generation, just recently says usb/device not recognized and doesn't light up when plugged into the wall either??? Any suggestions??

This came from another thread, but worked for me. Problem is with newest iTunes 4.62. Unistall iTunes, as well as its helper programs (Apple Application Support, Apple Mobile Divice Support, and Apple Software Update). Reboot, and reinstall iTunes. It will reinstall all the other ones and you should be able to connect your nano. Good luck.

USB Device Not Recognized - is my iPod toast?

Got a new computer recently with Win XP. When I try to connect my iPod with a USB adapter I keep getting "USB Device not Recognized" and if I click that I get "Try reconnecting the device. If Windows still does not recognize it, replace the device."
I can connect other USB devices like my compact flash cards etc. The iPod was working on my old computer.
Any ideas??
Thanks in advance for any help!!!

I had a new ipod and windows wasnt recognizing it or giving me the message "new hardware found" and then telling me the drivers were missing... this is what I did and it fixed my problem.
1. go to www.driverguide.com and sign up (for free)
2. download usbstor.sys & usbstor.inf (and take note of where you download them to)
3. update drivers by selecting folder you downloaded the two files to
4. restart computer
5. open itunes and then connect ipod
good luck

"USB Device Not Recognized. One of the USB devices has malfunctioned..."

I'm running Windows XP with external hard drive. When hard drive is connected, iPod will not sync and I get message stating "USB Device Not Recognized. One of the USB devices has malfunctioned..."
When disconnect the external drive, he iPod appears in My Computer. However, iTunes is on external drive; therefore music is not syncing onto iPod. I've attempted the 5 R's as well as searching for iPod in Device Mananger. When iPod is conncected, it is listed in Devce Manage as "Unknown Device."
I've changed drive letters on boh iPod and external drive and get the same message. Please help.

QRe: Zen MX Causes "USB Hardware has Malfunctioned" Msg from Windows XpyUhh, Yes.
I used to same cable to attach my Motorola Razr and the computer correctly found it and identified it as such.
I also tried another cable (brand new) same thing.
I went to recovery mode and did a "CLEAN UP" but no dice.
I also got my I.S. tech guy to look into it and on the USB page it say "UNKNOWN DEVICE"? when he tried to delete it it did not help, it just reappears as "UDVC"? Also in looking into it it seems to have no drivers.
He came to this site and tried to do somethinm through here but it did'nt work.
Now in listening to it last night it began to 'skip' or what I call 'HICCUP" terribly. Where a song starts and stops, during the middle of it. ? It's always done it a little but it has been getting more and more common and now? It's WAY worse about it.
It has never been dropped, or nishandled in any way. I bought the clear hard case to protect it. And only has about 300 songs on it. Never used for anything else. No vids no pics, nothing.
