Windows won't install USB device...infinite loop of connect and disconnect

I've been very happy with my Ipod purchases over the years but this one is the worst problem I have ever had. Purchased an 8gb Ipod Nano 3rd gen for the wife as a Xmas present and went to install it on my PC today but no luck whatsoever. The PNP manager seems to go into an infinite loop of connect and disconnect with the odd "Itunes has found a corrupt player ...." message but the device won't stay on the PC long enough as it promptly disconnects from the PC again!
My other 3 Ipods all connect and work quite happily on this PC, I've tried a few of the other "solutions" that seem to fix other "problems" but as the device does not stay connected for long enough I can't do anything with it!
Has anyone else had this problem and been able to fix it? If so, what did you do to correct the problem?
thanks
Marty

Thanks, tried that and much more - a very frustrating process.
I've just posted this on another thread...
I've tried unplugging everything and it still didn't work (I only have a USB printer, USB 1.1 hub and a USB phone connected). Funnily enough though connecting it to the USB 1.1 hub it works OK - go figure. Connecting directly to a USB 2 connector either on the front or rear panel and my PC goes into the connect/disconnect loop! My 1st and 2nd gen Ipod nano's and my Shuffle all happily connect to the USB 2 connectors on the front panel but the 3rd gen one does not want to know.
I think that Apple have got something seriously wrong here and it would be nice if it was acknowledged and a proper fix applied.

WHY, when I have nothing plugged in does Windows flag up a USB device that is does not recognise?

WHY, when I have nothing plugged in does Windows flag up a USB device that is does not recognise? When I check it a box comes up which offers a diagram that does not tell me which port it is? How do I check which port/outlet it actually is? Could

Recovery = Windows won't install from recovery discs

I have a dv6, performed recovery off the purchased 2 discs, and it says Windows won't install. Also, will not let me log into administrator...says my account has been disabled. Need help asap, on roomies pc.

I also tried using a HP Windows Recovery Disk from HP for my HP G71-340US Notebook Computer, but it repeatedly fails the installation with the message:
"No OS Flag Set on Unit. Please use EEPROM to set OS SKU value = 2. Error RStone S Update SRU option configuration is invalid, Loc # cound not be found in product #. Next step: Please use EEPROM to set Loc # in either SKU # or CTO localization code".
This occurs repeatedly when trying to run the Recovery Disk from HP.
I believe there is an EEPROM problem, but I do not know what to try next. I have backed up all my persoal data, but everything is wipped off the hard disk, currently. I can get into the BIOS, but that does not seem to be of any help. HP tech support is of no help.
Thanks for any help or recommendations.

Android / USB devices keep connecting and disconnecting on R7

My daughter has an R7, and she is having a weird problem with the USB ports on it.No android device can stay connected. As soon as you plug it, it makes the connect sound then the disconnect sound and keeps cycling between connecting and disconnecting. It is not related to the device as I have tried two different phones and one tablet all with different cables, all work fine on other computers. And I tried on the three available USB ports of the laptop, all behave the same. Searching online I found a lot of people with similar issues mostly unresolved. I did disable the USB suspend option in the power options without any results, as well as uninstall all USB hub so they would be reinstalled at boot time, and installed all optional windows updates. She is also experiencing another issue on her USB ports, we have a Samsung slim external DVD player that uses a Y USB cable for data and power that also works fine on any other machine. On her R7, when playing a Video, the video keeps making blocks at regular intervals like something is preventing the full data stream. Wondering if this is related. Apart from that, USB mouse, USB keys or external USB drives appear to work fine. Anyone with a similar issue and a definitive fix?

Thanks, but I seem to have found a solution to both issues. 1) Regarding the android devices that kept disconnecting and reconnecting, after readiong this threadhttps://support.microsoft.com/en-us/kb/2900614 I checked what registry keys were present on my wife's surface pro3 for
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_XXXX&PID_XXXX\YYYY\Device Parameters and found that there was three DWORD values in there that were not present on the R7SelectiveSuspendEnabled
EnhancedPowerManagementEnabled
DeviceSelectiveSuspended So I added these 3 DWORD and set them all to zero, and the issue is gone. You may not need the three of them, but I have not tested them one at a time yet. 2) For the External DVD blocky playback, it turned out to be quite trivial. Someone had enabled hardware acceleration in the VLC player settings. I reset all the VLC settings, and it worked fine from there. Hope this can help others

Obviously, syncing an iOS device with iTunes over USB is still supported in Mavericks. Calendar and contact syncing with iTunes is no longer supported. That has nothing to do with your problem.

IPhone 4s connects and disconnects from Windows 8

Apologies if this has been asked before as i'm sure it has but I can't find a solution.
I have a new HP Compaq laptop using USB 3.0, when I connect my IPhone 4s to my laptop it connects and disconnects every seconds, I've looked in the device manager and can't find anything to do with Apple in there.
Has anyone found a solution to this?

I have a set of 3 USB disk connected to my TC via a USB hud. I usually swithc the TC at night. When I restart the next day it stucks in amber state. when I disconnect the USB hub where my discs connects and restart, it start properly. Any hints?

I have a set of 3 USB disks connected to my Time capsule (TC) via a USB hub. I usually switch the TC at night. When I restart the next day it stucks in amber state. When I disconnect the USB hub where my discs connects and restart, the TC will start properly. Any hints?

LOL.. don't switch off the TC.. this is fairly typical behaviour..
Or try a different usb hub.. but you could well and truly run out of hubs before you fix the problem.
Are you running latest firmware for your TC?
What error message is coming up in the airport utility.. amber led is a fault indicator.. look up what the actual fault is and see if it is for instance overloading the usb. You are using a powered hub??
Get one bigger USB hard disk instead of 3 smaller ones.

Every time I connect and disconnect my iphone/ipad windows vista opens windows media player in the background. It then hogs all of my cpu. Does this happen to anyone else?

I am running iOS 4.3.5 and this has been going on for months now. I need to keep my task manager open to kill the task when I connect and disconnect my iphone or ipad. It hogs all of my cpu, sometimes opening 2 or 3 windows media players.

Sorry, just to confirm, I DID NOT ACTUALLY ANSWER MY OWN QUESTION!
I replied to the previous message from my iphone and I managed to hit the link to "This has answered my question" by accident!
I AM STILL LOOKING FOR A RESOLUTION TO MY ORIGINAL PROBLEM. CAN SOMEONE ALSO NIW TELL ME HOW TO GET RID OF THE GREEN TEXT TGAT SAYS TGAT MY QUESTION IS ANSWERED? That is a pain! It should at least ask you to confirm that your question is actually answered and you didn't hit it by mistake, like I did!

My iOS 6.1.4 is updated. i have other devices connected to wifi hotspot of my iphone5. Though my other devices appeared to be connected and shows an excellent cignal strength, i cannot access internet. hope this will be fixed.

I hope so too. So what have you actually done to fix your issue?

i have recently been issued a new laptop (lenovo thinkpad X230i, windows 7) and want to sync my existing iPod Classic to it. i set up iTunes (11) without any problems, however my ipod t appear in My Computer or in my iTunes library.
I've tried everything suggested in 'iPod troubleshooting' but nothing seems to work.

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.

Upgraded to Windows 7 - iPod touch - 'USB device not recognised'

Hi
I upgraded my laptop to windows 7 a couple of days ago (was XP). worked fine in XP. Just connected it expecting it to install the driver itself or something, but the 'USB device is not recognised'
Any ideas?
Thanks

Make sure you have the newest version of iTunes, that should fix the issue.

Boot Camp - Windows won't install

Hi,
I'm running OS X 10.10.2 on my iMac 7.1 (2.4 GHz Intel Core 2 Duo, 4 GB 667 MHz DDR2 SDRAM). On completion of Boot Camp partition Windows 7 DVD won't install - I get a black screen prompting me to select boot mode. However, keyboard and mouse are disconnected at this stage leaving me powerless to do anything. There's nothing wrong with the Windows 7 DVD, I might add - installs perfectly when running Parallels Desktop 10/Parallels virtual machine. Can anyone tell me, how to resolve this annoying issue?

Hi CellarDwellr,
Thanks for your answer.
Although my install DVD does indeed bear the "OEM" mark, I don't think the "OEM" is the root of the problem, as the DVD installed perfectly on my iMac by means of Parallels Desktop 10. Furthermore, I made a perfect and smooth installation of Windows Vista (OEM DVD) on my iMac some years ago by means of Boot Camp (running Snow Leopard at that time).
Hence, I'm inclined to suspect this to be an OS X issue rather than anything else.
Finally, I did comply with the Boot Camp manual on both occasions.
Regards missil1
You can't just compare your windows 7 oem to your old windows vista oem. There are many - probably hundreds - of oem versions out there. You probably have a limited notion of what "oem" stands for. An OEM version of Windows is a special version for a specific computer or models of computers and none of them are for Apple. Dell or HP might sell OEM versions of windows, tailor made to work with their models of computer. Which means they preinstall drivers specific for, say, a Dell Studio laptop. Often they will also force a partitioning scheme on a computer's harddrive as well. If it worked in Parallels, you were lucky.
If you want to try Boot Camp again, use Boot Camp-assistant to delete your Boot Camp partition and start over.
