Device not recognized via USB

Hi, i have iPad1 fw4.3 that is out of warranty now. It worked fine.
Suddenly neither windows 7 nor lion would recognize it when connected with usb.
Windows 7 throws "USB device not recognized" message, Lion does nothing.
Im aware of many threads on this subject but nothing helped.
As i'm a game developer i need ipad to test my games, and without usb connection it is useless to me.
I cant afford another one so it's quite important to me.
I'm also form a country not supporded by apple so there is no place where i could take it for service.
iPad is charging fine and works fine.
It shows like "Unknown device" under windows device manager.
Not detected even in Recovery mode, so i cant restore. Any other way to update fw ?
Tried with 3 different cables that work with two ipods on every usb port.
Tried on 3 different windows 7 pcs.
Tried with a fresh install of lion.
Tried leaving all devices unplugged for some time.
Tried disabling network adapters everywhere.
Tried reinstalling itunes, deleting plists and kexts multiple times.
Any thoughts ? Thanks

Update for those interested with similar problem.
Tried DFU, wasnt detected in it also.
Not sure but it seams it is detected when i do a settings reset > connect to a wifi network > do a settings reset
But when its detected it always disconnect itself after 5-10 second unless i do something with it. Its like it disconnects after a 5sec idle.
So, as soon its detected and itunes shows up i start backup to give the device something to do.
That gave me enough time to select ios5 ipsw, itunes to unack it and start the update.
The update went fine, ipad didnt disconnect itself during the procedure.
Unfortunately even though im on ios5 and did full erase the problem persists :/

IPOD not recognized via USB - A lot of trouble shooting already done.

I got a new 80GB iPOD to replace the 4th gen 40GB that just died (HDD issue). I cannot get the computer to recognize it via USB. I had the same problem with my 40GB via USB, however it would usually work via firewire. This new one will not let me use firewire, so I am forced to try to resolve the issue. I know this has come up before on here and I spent about 3 hours last night going through old 'USB Device Not Recognized' posts, but could never find anything similar. This is where I stand. Any help would REALLY be appreciated, because I am pulling my hair out over this.
All previous Itunes have been deleted and Itunes 7 has been installed. This is on WIndows XP Pro.
1. I know it is not a defective IPOD or USB cable because I brought them to work (a non Itunes machine) and plugged it up. IPOD was immediately recognized as IPOD /USB Mass Storage Device.
2. I know it is not the USB port at home because I plugged other devices (Klipsch Promedia speakers / Mouse / Keyboard) into the same port and they worked. Incidentally, this is a front USB port, however, I get the same result if I use a rear port.
3. It is not recognized in Itunes or in 'My Computer'. Only recognized as 'unknown device' in Device manager.
When I plug it up at home, it goes through all the 'new hardware detected' crap and then 'you new hardware is ready to use', but then after about 3 seconds, I get the 'USB Device Not Recognized....USB device has malfunctioned ....'. message. If I go to device manager and uninstall it and then retry. I get the same thing. Even f I reboot between tries.
So, I have pretty much ruled out a hardware problem. I think I read on here somewhere (or a link from Apple) that there was a Microsoft hotfix issued for this issue last year sometime (I think it was a SP2 compatability issue), however, I cannot find the fix. The link I had talks about the hotfix, but there is no file. Also, since the issue first appeared last year, I would think it has been resolved in one of the updates since then.
PLEASE help me out if you can. Thanks!

Here is what worked for me:
My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

Running Windows 7 via Bootcamp - USB Device Not recognized.

I am running Windows 7 64 bit via Bootcamp on my MacBook Pro (2012 non-retina display). USB devices are not being recognized within Windows 7 (USB Device Not Recognized error).
I have done some research and tried a few possible solutions but nothing has worked so far. Here is what I have tried:
- Uninstalling all USB drivers within windows and then restarting to let Windows re-install the drivers.
- Uninstalling Intel 3.0 USB Host Contoller and restarting Windows.
- Repairing the drivers using Bootcamp setup.
- Uninstalling bootcamp and re-installing bootcamp services.
The USB drives are working fine within OS X, just having issues in Windows.
Any suggestions?
Thanks in advance.

3.0 is on your OS X DVD. Clearly spelled out in the guide in Boot Camp Assistant, and here -
www.apple.com/support/bootcamp : manuals, look for 10.6 pdf version.
3.0 is pre-requisite for any other
OS X comes with Boot Camp Assistant and you access 3.0 drivers while in Windows.

80gb Classic won't sync or charge; "USB Device Not Recognized"

I have an 80gb classic, and a 5th gen. 30gb ipod both with the same issue. I recently rebuilt mine and my husband's computers with new MB's and Processors. I reformatted the HDD's and then installed all necessary drivers and the like along with the newest itunes 9. My ipods had no previous problems and worked like a charm 5 mins earlier.
I hooked them up to my computer and windows came up with an error message saying "USB Device Not Recognized...one of the usb devices has malfunctioned and windows does not recognize it." I put in my other ipod, same error message.
I have tried everything to fix this including, unplugging all usb's but ipod and trying all usb ports, reinstalling usb drivers, switching to 1.1, uninstalling itunes completely and using older versions 5-8, wiping OS and installing vista instead of XP, putting ipod into disk mode, resetting ipod numerous times, among some other things. This error message comes up on all computers in the house (4) including ones that have not been wiped or upgraded.
In addition to windows and itunes not seeing it, it will not charge via USB or wall AC power. The Ipods are devoid of charge now, but when they were full on battery life they still played music through headphones and stereo with no issues, they just won't do anything computer related it seems.
I have not given up hope because I have about 20gb of music and vids I foolishly didn't back up and I want it back. How is this possible that 2 ipods were fine one second then broken the next? Please, Please, Please need help.

I have a Dell Laptop that I've been synching my iPhone with for six months. Now all of the sudden the connection has been lost. I'm having the same problem as you describe and have tried everything I have seen on this forum and elsewhere to fix it, but nothing is working.
I think it is an issue with the driver, but I have confirmed that usbaapl.sys driver is installed in "Program Files," "Common Files," "Apple," "Mobile Device Support" folder. I tried copying the driver and putting it in the main Apple folder, but that doesn't help either. I have tried removing and reinstalling iTunes multiple times, rebooting my iPhone and computer (many, many times). I've tried updating the driver and pointing the USB device directly to the driver, but it does not see it. The strange thing is that when my iPhone is plugged in, it charges just fine. It just won't connect to iTunes or synch with my outlook anymore.
Does anyone have any suggestions? This is a major issue for me as I have to synch calendars to be able to function between work and home. Doubly frustrating that it used to work and now it does not. The only thing that has changed is that I installed printer software and updated iTunes. No other changes to my computer that I am aware of between when it worked and now.

Shuffle 2 - device not recognized... USB Driver?

I got the Shuffle 2nd Gen, plugged it into my PC, and it blinks orange with no install box on Windows, and a "device not recognized" error. Nano works fine on my computer, and my Shuffle works fine on a Mac laptop, so customer service told me it must be a problem with an outdated USB driver.
Here's the problem: I don't know where to get the USB driver update, because my PC is custom made, and I don't know who the manufacturer is. The customer service guy says to find the maker of the motherboard, but I'm not 100% sure how. My Device Manager says "VIA USB Enhanced Host Controller" is the only listed Enhanced (2.0) USB Port. I used a program to find the motherboard manufacturer, and I think it's a "Chaintech 7VJL APOGEE."
Can anyone help me find a USB driver? Might something ELSE be the problem?
(I'm reposting this from a reply I wrote to a different thread)
iPod Shuffle 2nd Generation Windows XP Custom PC

Hey 655micha,
I'm sorry you're having an issue with a USB device. Do you get an error window that pops up? If so what does it say? Have you checked Device Manager? Is is just one device that isn't working? Has it ever worked before? Is it just one USB port in particular that isn't recognizing devices?
What model do you have? Here are the steps to find your product number. FN + ESC is the easiest way to find that information.

IPad mini USB device not recognized

Trying to get my laptop pc with Windows 7 to recognize my iPad mini on iTunes v11. Actually, trying to get it recognized by my pc at all. It shows up as an Unkown Device when i plug it in, as well as in my Device Manager. I've gone through Apple's online Troubleshooting guide (http://support.apple.com/kb/TS1538), but when I click Hardware IDs in the Devices tab as requested, it shows up as Unrecognized (USB/UNKNOWN) still -- the Troubleshooting guide does not adress this scenario. I've been connecting it to several funcitoning USB ports (that recognize my iPhone 4S just fine) via the "lighting" cable that came with the iPad mini, with the same result.
This is a very simple Windows 7 laptop so it strikes me as very odd that this wouldn't work simply. I've checked around the net and seen people with similar dilemmas without any known solution yet, as far as I can tell. Please advise, Thanks.

I tried the method mentioned and it didn't resolve my problem.
After much frustration, I opened Device Manager on my PC with my iPad Mini conected in one USB Port, I located it as Another Device (Not Recognized) / iPad. Double Clicked iPad and manually Reinstall the Driver.
It wasn't recognized as Apple Mobile Device in Universal Serial Bus Controllers before.

USB device not recognized when in Win XP

When I plug my Ipod touch into the computer via the cable, I get an error message
"USB device not recognized". I've tried to delete and reload Itunes, I've reset the Ipod and reset all the original settings. I've tried several of the USB ports and also tried 3 different cords for the Ipod. Can anyone help me??? I can get it to plug into my daughter's computer at her house, but not on my computer... this is getting frustrating!

Thanks for welcoming me... wish I didn't have to come on here though... I wish the IPod(1st gen) was working well. I just downloaded the new Itunes 8.2.1 on my computer when this started. My son-in-law's IPod (2nd gen)plugs in and is acknowledged just fine, for mine, even when I bit the bullet and decided to erase the whole thing and start anew, is still telling me "USB device not recognized". Very frustrating. So it's not only not connecting to my computer, it's now erased. Before I could at least play games, can't do anything now... (sigh)

USB Device not recognized by windows

When I first plugged my iPod into my computer, it went through the whole recognizing new hardware thing. Installed the drivers, then said that the new device was ready to use. But then I get a message that says "Device malfunction, device not recognized by windows" or something to that effect. I only have 3 days to return this iPod...anyone have any ideas? Thanks.

I'm not very familiar with the Windows OS but try this tip I picked on the forum up a while back, hopefully it might help.
1. On the Start menu, click Control Panel.
2. Double-click the System icon.
3. Click the Hardware tab.
4. Click Device Manager.
5. Scroll down the list of devices to the Universal Serial Bus controllers
6. Click the plus icon next to the Universal Serial Bus controllers.
7. Double-click one of the indented USB Root Hub entries.
8. Click the Power Management tab.
9. Deselect the "Allow the computer to turn off this device to save power" option.
10. Click the OK button at the bottom of the window.
11. Restart the computer.

USB Device Not Recognized

Operating system: Windows Vista
Error: USB Device not recognized
While actively on the computer, we suddenly got a message stating that the USB Device was not recognized. The only thing plugged in to the USB port was a mouse. Tried all the ports, same message. Tried another mouse, same thing. Tried a thumb drive, and low and behold, 2 of the 3 USB ports worked. Tried a URL from MS which is supposed to help with this exact problem and possibly fix it: http://windows.microsoft.com/en-us/windows-vista/Tips-for-solving-problems-with-USB-devices
This didn't work.
Contacted HP support and they wanted me to restore back to a restore point as well as updating my BIOS. After searching the issue more extensively using Google, I found that several people said to do this:
Shut down the computer
Remove the power plug
Remove the battery
Put the battery back in
Power up the computer (without the power plug)
This forces a hard reset.
Almost as if by magic, the problem disappeared. A much simpler and less technical solution to the problem than what HP recommended!!!!

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
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".

USB Device Not Recognized on Windows 7 - USB mouse

I have a 4 week old Inspiron 1545 with Windows 7 Home premium that has developed an error: USB errors while trying to install a Microsoft USB mouse on this Laptop. Interestingly, my Microsoft USB Mouse installed perfectly first time and worked for about 2 weeks, and then failed. In looking at the system restore points, it tells me that there have been two driver updates to the USB environment since the unit was shipped from Dell. I wonder if an automatic update from Microsoft has somehow inadvertently updated or replaced a Dell factory driver.
Two nights ago I spent 45 minutes with Dell tech support doing remote control bug fixing on this laptop. They werent able to fix it (in the time allowed). They downloaded at least one of their newest drivers onto this machine and rebooted it - and they seemed pretty savvy - but still not working. So I went ahead a did a system restore to a point about 10 days back because I could see that a USB driver would be affected (as shown in the system restore menus), and I would like to compliment Microsoft on this very cool functionality!
At this point, I've unplugged the USB mouse , used the Device Manager to delete the 'unknown device', and done a system restore back to what I suspected was a working point. But still getting a 'Device not recognized' warning every few minutes, and still don't have a working mouse. I don't want to have to do system restores back to pprevious dates, although I suspect this is one solution.

Hello,
I just wanted to let u know, I had this same issue for about 2 weeks. Basically what happened was a bad install of my AMD Chipset drivers. When I attempted to upgrade, the install didn't go all the way through.
I then restarted my system, and BAM! No Mouse or Keyboard functionality thru USB.
Even when I went into SAFE MODE the Mouse and Keyboard were not functional. The only time they worked was when the computer first attempted to start, BEFORE windows loaded.
So, this means that your issue is a software problem.
I thought it was some other software that I installed, and ran a restore session, but that wasn't the issue. Still no functionality.
I even tried removing my CMOS battery, to reset it, since some people said that had solved their problems...Still nothing.
I then read other forums around the web using my Android phone to try and find a solution, only those solutions were no help.
I was also advised to run: MSCONFIG and Hide all Windows programs and then stop every other driver, source from loading (of course if my mouse and kb worked, I would have tried that).
I had even read that because I was using USB, that I should try using a PS/2 Mouse and Keyboard connection.
It took me 2 weeks to get the correct PS2 adapter that worked, which would essentially allow me access to my system again...
I Purchased a USB A Female to PS2 (MDIN6) Male Adapter (for Mouse) from http://www.SFCable.com
This my friends, was a lifesaver. I only have one PS2 port on my system, so I used my mouse to try every option I had previously read about. Of course you cannot type because the keyboard doesn't work, so you need to know the location of the folder where
the programs you are trying to run are.
So, a little after I got back into my system, and I closed down all programs, the warning screen came up that ALL of my USB Ports failed and could not be updated. I even Uninstalled every last USB port from the System Properties and restarted, and still
that didn't work.
I had forgotten that during the time when this problem arose, there was a failed install of my AMD chipset drivers, so luckily I had not deleted the source file and I tried to reinstall, and VIOLA! I'm back up and running and my USB ports are restored
and everything is working!
I hope this solution is able to help other people out there.
Thanks,

USB Device Not Recognized issues

I have a Qosmio X505-Q860 and I've been getting the 'USB Device Not Recognized' error constantly for several months. I've never plugged anything into any of my USBs and the error is now causing a nice Blue Screen (which happened about 4 times yesterday within 1 hour). I've tried uninstalling the problem USB hub but it keeps telling me that it failed to uninstall (I'm on my administrator account when doing this). How in the world do I get rid of this so my computer stops crashing and driving me crazy!?
Edit: I should also mention that everything is up to date (I check often and checked just now).
"A stopped clock is still right twice a day."

I suggest trying another USB cable. If you are positive that your cable is not the issue then try resetting the iPod and booting into disk mode (Hold menu+select down until Apple logo appears. Then hold menu+play/pause down and the iPod will go into disk mode, see if the computer recognizes it then. If that works then their is either a software issue on the computer or a firmware issue. Worth trying to restore but backup all your iPod's files first!

"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

Try a different port and a different USB cable.
