USB Connection Not Recognised

Up until a recent upgrade to Windows XP, iPod Nano has been working fine.
The last few weeks I had intermittent success connecting often involving relodaing iPod or iTunes software.
Now nothing all i am getting when i connect the iPod is USB Device Not Recognised, I have tried all the USB ports, resetting, hard disk mode, obtaining the drivers usbstor which I found mentioned in another thread.
Is there something i have not tried?
I have followed the list in the Apple Tech Pages regarding the iPod not appearing in Windows or iTunes however this seems to be a problem ocurring before that step is even reached.
ideas?

Not sure if Time Zones are delaying any responses but I thought I'd add that I have just tried all the old favourites with my Laptop and I am getting the same deal.
Currently the iPod is working and playing music so is it possible my Cable is stuffed and needs replacing? has this happened to others?

USB Device Not Recognised - unable to connect

I am having a serious issue! My ipod was working perfectly, then for no reason i got the error message 'USB device not recognised' from my PC when plugged into a 2.0 port. I am unable to mount to restore to factory settings - definitely isn't a USB connection issue - I have tested the same port with my printer and it works perfectly! When I troubleshoot, The PC tells me that it is an unknown device, and that 'No drivers are installed for this device.' Where can I get Drivers for an IPOD 4th Gen?

This is a shocker! I've now tried the following:
- re-setting iPOD to factory settings
- re-formatting iPOD
- removing then re-installing Itunes, both old and new
version
- resetting the COM thingy
- re-installing iPODservice.exe
- deleting all systems drivers and re-installing
- re-setting iPOD whilst connected
- using old Ipod updater 2004-08-06 and the later 2004-11- 15 version
All I have now is an empty iPOD and a music library with 30gig of tunes within it, with no way of marrying the 2 together. It's been 2 months now and I've really got the hump!
I think that there is a serious defect with either the iPOD or the software - we are not isolated cases! (have you seen how many discussion strings there are on the same subject?)
If you manage to find any other possible fixes, please let us know! In the mean time, I'm off to see about getting one of those new Sony thingys!

Ipod "usb device not recognised" on one computer but works with another!

I have a 60GB ipod video and a 2GB ipod nano. Both connect fine to itunes on my work laptop but will not connect to my home laptop. They have previously worked fine with the home laptop but now when conected the message "usb device not recognised one of the usb devices connected to the computrt has malfunctioned". I have tried reinstalling itunes several times and tried the usual reset of the ipods etc but nothing seems to work.

If you have more then one USB port, try the other port.

Updater - ipod usb interface not recognised at PC

I have a a 15GB ipod with dock connector. It was working fine playing songs and was visible from my Windows XP PC via the single USB cable. I could see ipod files.
I downloaded ipod updater 2005-09-23 and selected update.
Thereafter :-
Ipod is no longer recognised by the PC, it gives - "usb device not recognised" when the menu button is pressed.
The ipod screen is blank. Reset gives the apple logo then the icon asking to connect the cable ( which is already connected).
Other usb interfaces on the PC give the same message.
Other devices connect OK to these USB interfaces.
The cable was working prior to the update.
Another PC ( compaq laptop ) gives the same "usb interface error message" when the ipod is connected.
the problem is within the ipod usb interface.
The updater appears to have corrupted/changed the ipod "usb interface"
I am unable to update again or restore as no connection available to the PC.
How can I restore the ipod's usb connectivity?

I went out and bought a firewire cable today.
The ipod was immediately recognised and ITUNES updated. I then connected the USB cable. It now works OK as well. I am so relieved.
On the updater screen, if you right click on the top bar, it drops down the "ipod models" updated by this version.
For my model it shows a firewire icon on the ipod. Is this co-incidence? I expect so.

USB device not recognised - comes up when I plug i-pod into PC

When I plug an ipod (have tried 2) into my PC I get the message
USB device not recognised
One of the USB devices connected to this computer has malfunctioned and Windows does not recognise it
I have tried several USB ports and 2 different connecting cables
Help!!
Thanks

Try to restart your computer?
If you have one of the newer iPod's it could mean the service pack is not up to date on Vista/XP
To check your service pack, right click on My Computer and click on Properties.
Vista should be service pack 2, and XP service pack 3
iTunes HAS to be updated to iTunes 10 or later
If it is not a new iPod, you could have to update your USB drivers
http://support.apple.com/kb/TS1538 follow that and it should work
If none of those resolve the issue, try uninstalling and reinstalling iTunes

6610, dku-5, usb device not recognised

Hi...
Have a 6610 and Windows XP (SP 3) and need to save all my data... so trying to use PC Suite. Bought a DKU-5 cable:
1. Installed driver from the accompany DKU-5 CD and installed suite... when asked, connected cable and phone. Not recognised
2. Uninstalled all the above, including registry settings
3. Installed latest downloaded driver from the Nokia website. Connected cable and phone to PC. Not recognised - sometimes the system just stays quiet, and sometimes i get an error message that the device has failed or not been recognised
4. Tried running PC Suite from the original CD... doesn't find the phone
Grateful for any suggestions?
TIA

Hi aspergerguy...
First, thanks for the response and sorry for the delay in replying... but have been trying out various routes.
1. Your suggestion does not even come up in the interface options i get...
2. Have also bought a CA-42 cable and tried that.
3. Have downloaded the latest drivers from the Nokia site and the latest PC Suite...
4. Have aggressively uninstalled by removing even registry entries
5. Have tried installing and rebooting in various configurations
Nothing works. The CA-42 cable goes as far as saying "New hardware detected" but then gives the "USB device not recognised" error. Just doesn't seem to recognise the driver.
Regarding the COM port suggestion... if i go through the Nokia Connection Manager and click the DKW-5/CA-42 options which are listed under Serial cables, alli get is a COM1 option...
Any other ideas?
Cheers...

Usb device not recognised for ipod touch

Just bought new ipod touch. Connected ok to start with and managed to set up but I know keep ketting the message 'USB device not recognised'. Says something about no drivers installed, but then system says no updated drivers available. Have followed all the help tips, reset the ipod and the only thing I haven't done is reinstall itunes. Is that likely to help? Is the problem likely to be the ipod itself? Any help much appreciated.

have a look at this support article.

Usb device not recognised and sudden shut down. iphone doesn't appear itune

Hi everyone.
New to these forums.
I am travelling atm. Just received a new white iphone 3gs 16gb 6 weeks ago as a replacement on insurance from uk.
No previous problems. Yesterday phone suddenly powered off.
completely dead with around 30% baterry charge remaining.
now briefly shows charge icon when pressing on off button.
connect usb charger shows charging icon, disconnect shows not charged.
have left on for several hours and no more charge stored.
connect to pc and sound denotes usb connection, however message appears (vista)"usb device not recognised".
iphone does not appear in my computer or on itunes.
am travelling down through africa for the next 4 months so cannot visit store or post to apple or receive replacemant until return to uk in april.
is this issue fixable?
moved to iphone from ipod 2 click wheel as that was extremely unreliable and crashed constantly.
have had 2 ipods, 1 iphone 3G and this 3Gs. only 3G worked without problems for a year. All other items failed repeatedly within weeks or months.
are apple going to produce a reliable product one day? functionality is great, reliability is less than 3rd rate.
can anyone help as i face 4 months overlanding with no music, translator apps or phone!!!!
desperation creeping in.

Hello iphonephan,
Try following the steps in these articles (try them in the order listed below):
http://support.apple.com/kb/TS1495
http://support.apple.com/kb/HT1925
http://support.apple.com/kb/HT1926
Another thing you can try is to import the pictures when that prompt comes up and then delete the pictures on the iPhone (you can also email them to yourself from the iPhone before deleting them). Once the camera roll is empty on the iPhone try connecting to the computer to test.

Ipod not recognised by Windows, USB device not recognised

Hi hope someone can help
I have recently received my ipod back from Applecare who have sent the ipod back in ' working order ' but it will no longer be recognised by my windows. It says USB device not recognised and i cant find, nor will it install drivers that i located on the ipod updater etc.
I have tried several methods on this forum but none seem to work.
The letter from mycare says the iPod is formatted for a computer operating Mac OS X. Although i stated wi use Windows. But the leter states this can be changed bu installing the updater, but this wont make a diff as comp still wont regonise the device after i have followed there instructions. Any advice?
Thanks

I'm not really up on the complexities of the Windows OS but try this tip I picked up a while back, hopefully it might help.
"USB Device not Recognized in Windows".
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 recognised by windows 7 on hp pavillion dv5094ea

Im having problems since ive updated my HP dv5094ea from windows xp up to windows 7,
Since the upgrade my usb ports arent functioning, i keep getting an error bubble saying
"Usb device not recognised" - device has malfunctioned
ive tried several trouble shooters including going into device manager and deleting the INFCACHE.1 with no luck, im starting to assume its a driver update issue...
can anyone help?

Hi:
W7 should have had the USB 2 drivers native to its driver database.
The only suggestion I can offer is to manually install the Vista graphics driver for your model which may have some motherboard drivers included.
Download and run the file below. You will probably get an unsupported operating system error.
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-48969-1&cc=us&dlc=en&lc=en&...
Close out of any error windows. Go to the device manager. Click to expand the display adapters category.
Click on the display adapter listed there. Click on the driver tab. Click on Update Driver. Select the Browse my computer for driver software and browse to the driver folder that was created when you ran the file.
That folder will be located in C:\SWSetup\sp35203. Make sure the Include Subfolders box is checked and the driver should install.
After you reboot, see if the USB ports are working.

Usb device not recognised

hi i have a problem when plugging in my ipod touch, it says in a little speech bubble at the bottom corner "usb device not recognised, one of the usb devices attached to this computer has malfunctioned, and windows does not recognise it"
ive tryed everything, ive updated the driver, ive uninstalled the driver, and nothing comes up in itunes. the ipod does nothing when plugged in, it does not charge as well when plugged in. ived tryed in itunes the diagnostic test but when i click it it says "itunes has encountered a problem and needs to close"
please help me!!!!
thanks, calpol55

I am having the same problem. I went through all of the steps already listed (updating drivers, uninstalling drivers, uninstalling iTunes and all related software, reinstalling) and still no luck. I also tried syncing to a new computer, but am having the same problems. My Touch does at least charge when plugged into either computer, but is not recognized by either computer in iTunes to actually sync. The problem seemed to start after I updated iTunes on both computers, so I tried going back to the previous version of iTunes, but then I couldn't get iTunes to open because my library had been updated by a newer version of iTunes, so the old version wouldn't work anymore.
My Touch is not yet completely worthless since I can still charge and download apps and music straight to my Touch, but I can't organize anything very well and can't easily make new playlists or add new playlists from iTunes.

Libretto - USB Device Not Recognised error message

Hi there
I have a workaround for this problem which ocassionally happens. It is just to reconnect the USB hub(as recommended by Windows). I was just wondering if someone knows why this happens and how to fix it. The error is :--
"USB device not recognised. One of the USB devices attached to this computer has malfunctioned, and windows does not recognise it.
USB Roob Hub (2 ports) - Unused Port, Unknown Device.
Recommendation: try reconnecting the device. If Windows still does not recognise it, replace the device. "
I look forward to hearing back from you.
Kind regards
Julia.

Hello Julia
It is always advantageous to mention which model you have exactly. Obviously the external device is not recognized correctly. Check if there is some driver that must be installed before you can use it properly.
