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.

Plugged USB into my MBP and it shut down. Doesn't restart, what to do?

I have a MacBook Pro (2009) with an OS Mountain Lion from Austria. Now im in the Philippines and plugged in an USB of a friend and my MacBook shut down.
First I thought I have no battery left, but it that wasn't the case.
Then I saw that the white light next to the Bluetooth thingy is on.
could it be that there is a virus on the USB?

Thanks for your fast respond! but I don't know how to do that intel restart when my macbook refuses to turn on.
I see the white light turning on, but I don't feel the hard drive turning on (if you know what I mean) I don't know how to explain it in a professional way, so thanks for bearing with me!

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

My phone was fully charged and suddenly shut down and wont turn back on iPhone 4

my phone was fully charged and suddenly shut down and wont turn back on
iPhone 4

Hi there,
I would recommend taking a look at the troubleshooting steps for unexpected power off issues found in the article below.
iPhone: Hardware troubleshooting
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Issue not resolved
My issue is still not resolved. What do I do next?
Contact Apple Support.

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.

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.

Itouch - USB device not recognized and Itouch now no longer works

I'm now on my 3rd Itouch since December all due to the same problem. All seemed to be going well with my 3rd replacement Itouch. Having loaded most of my cd collection into ITunes the night before I was going on holiday I synced my Itouch. Some sort of automatic download took place I think from Microsoft and suggested my drivers were being updated. Next thing I got message to restore my Itouch to factory settings. I did this and all the problems I had with my previou Itouch's started again.
When I now plug my Itouch into my laptop it says "USB device not recognized" and the Itouch will not switch on. I've done everything including reinstalling Itunes, holding down the power and home key but to no avail. Looks like I'm going to have to send my Itouch back again. I have a suspicion that a Microsoft download is corrupting the drivers. If anyone can help I would be very grateful. I really like my Itouch but the fact it keeps failing leads me to wonder if I should opt for something else.

I had success with the holding down the keys and connecting to usb and using itunes to restore firmware like they show here

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.

Same problem here, wondering if it has been caused by a recent OAD ?

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

USB Device Not recognised on XP Iphone 3G, but fine on win 7

I wonder if anyone can help me?
I plugged my Iphone 3G into my Work computer (win 7) yesterday and installed Itunes with no problems. I didn't sync or anything, I authorised my work computer as well.
I then went home and the second I plugged it in to me Dell d610 on Win XP is says USB device not recognised. I've looked at various forums and have unplugged and turned off laptop and then uninstalled USB root hubs but it will not work.
I then come into work today and find it works fine on my work Win 7 machine.
It's not the computer as I have 3 win xp machines at home and it's the same with all of them, 1 of them was patched a few days ago but the others havn't been patched since October.
I wonder if anyone knows what it could be?

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

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...
S
