Ipod showing up as "unknown usb device"

I'm betting this is the same problem as "windows doesn't recognize my ipod" but I wanted to make sure. I got the nano for christmas, successfully uploaded happilly to it for a few weeks and lately my computer keeps saying "the usb device has malfunctioned" and it can't identify it as an ipod. An apple store already restored the thing, it works on other computers, but still not on mine. I followed the instructions for turning iff power saving on the usb hub when using a laptop and that fixed the problem for exactly one day. Now it's useless again.
Anyone got a suggestion?

i've encountered the same..try reseting your ipod...discon it..then hold both menu and center button until ipod turns off and the apple logo appears...wait for 5 sec... then insert it again..see what happens...or transfer it to another port...u should have 2 ports there..or are you using a 1.1 usb port? naturally most pc does not recognize if it is a 1.1 usb port..try installing the suggested 2.0 card installer...good luck!..

"Unknown USB Device"

I got my 2GB nano last Monday. I could successfuly install it on my laptop and upload some songs to it. That done, I wrapped it again and gave it to my wife, so she and the kids could "surprise" me for my Birthday. Yesterday I got it,listened to the "sample songs that came with it", and today I tried to upload some more songs, but to no avail. Everytime I plug it in, all I get is an error message from windows, stating "Unknown USB Device". I tried everything from the iPod support site and from Windows help, but the nano simply won't be recognized. Oh, I tried to hook it up to my desktop at home as well, but nada as well. Same message.
Is my cable fried? Is my iPod connector fried? Can someone pinpoint the problem?
To worsen things even further, I live in Brazil, where the first nanos won't be around until Christmas, and support is but a dream...
Help!

These steps should help you with the 'Unknown USB Device' issue, Ruy:
First, make hidden folders visible. Open My Computer and choose Tools/Folder Options/View tab. Click on 'Show hidden files and folders' and click OK.
In the Add New Hardware Wizard, have it search in C:\windows\inf for usbstor.inf. This file is required for windows to properly configure the driver. If Windows finds the driver there, you're done.
If Windows does not find the proper driver there, copy usbstor.sys from C:\windows\servicepack\i386 to C:\windows\system32\drivers.
If you can't find the usbstor.inf file on your system, you can get it here: usbstor.inf
After copying the usbstor.inf driver file to C:\Windows\inf, right-click on My Computer and choose Manage.'
Click on the button labeled 'Device Manager.'
Click to open the list under 'Universal Serial Bus Controllers.'
Right click on any mass storage devices with the exclamation icon next to them and select 'Update Driver.'
Check the option 'Install from a list or a specific location' and then click to continue.
Check next to 'Include this location in the search' and enter 'C:\windows\inf'.
Click on 'Next' and follow the steps to complete the driver installation wizard.

Disk won't mount - Unknown USB Device (Link in Compliance Mode)

I have an HP Envy DV7 (dv7-7243cl ) with Windows 8 Pro x64. My Western Digital 2 terabyte My Book USB3.0 external drive periodically won't mount ( sometimes it will, sometimes it won't). The drive has its own power source.
When this happens Windows device manager shows - Unknown USB Device (Link in Compliance Mode). This can happen if the system is up and running and I plug the drive into the USB port or on system startup where the drive is already plugged in.
Any clue how to fix this?

Well, the problem is that - as outlined in one of the articles I linked to - some USB devices will not work in Safe Mode; that may have to do with the fact the Safe Mode is only meant to be a troubleshooting tool, not a regular way of booting up. Did you have the USB devices attached while upgrading to 10.6? That would also be a problem - I unplug everything except keyboard and mouse.And, did you repair permissions after the upgrade? If not, do it now.
And, the other problem is the fact that you wait 1 - 2 years before addressing the issue; when you had it in for the last repair and it still exhibited the same problems afterwards, you should would have taken it back, possibly with some screenshots, exact notes of how/when/error messages, etc. and insisted on having it fixed or replaced.
So, I'd run the Apple Hardware Test (after you make sure that you have a complete backup) - instructions here:

when i attach my iphone 4 with computer it shows one of the USB devices attached to this computer has malfunctioned and windows does not recognize it,now what can i do ..plz help me

I would first try unplugging All the USB devices plugged into your computer, and then plug back in just the iPhone and see if that is recognized. Also, do you have the latest version of iTunes for Windows installed on your PC, as you need to?
Hope this helps

Unknown USB Device when MuVo TX plugged in USB P

The following message came up when I plugged in my MuVo TX in a USB Port
Using WIndows XP
USB attached has malfunctioned
Windows does not recognize it
Unknown USB Device
Does this mean that I have a faulty player? When I first bought it on January 2 2005
I installed approx 25 songs and it works perfect. Now that I want to change these songs
to new ones, my MuVo TX is not recognized by Windows XP. Tried several other
computers with same results.
Can any one suggest a fix?
Thanks

If other PCs are giving the same error, then I think you can be sure the player is at fault somehow.
Have you tried the recovery process? Download the latest driver (if required) and firmware from http://www.nomadworld.com/downloads/drivers. Install the driver file (if required). After you have installed the driver, press and hold the PLAY button, continue holding the button while inserting the player into the USB port for about 0-5 sec. Run the firmware update file and check/tick the 'Format Data Area' check box and click on 'Start'.
If this doesn't help then I think you can be sure the player is faulty.

Presario V5094EA, usb device malfunctioned, unknown usb device

product: presario V5094EA running win XP,
hi am having a roblem with the usb ports on my laptop they were working fine up untill two weeks ago when they just decided to stop working,
now every time i plug something in they first find new hardware then it reports back a device has malfunctioned, unknown usb device, whether its a memory stick or my usb modem
i have formatted the hard drive reinstalled all the drivers from the recovery discs,
i even tried the information in an earlier post about disconnecting the battery for a period which i did for half an hour, but got the same response when i connected it all back up.
am beginning to think this could be hardware related does any one have any ideas before i go buy a new motherboard,
the laptop is about 6 years old now so well out of warranty,
thanks in advance

It should do a progress reading with percentages. If it ran all the way through and did not say anything was corrupt then I am afraid you have a hardware issue going.

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

IPod Nano: Error Message "The USB device has malfunctioned and Windows does not recognise it"

Hi everyone, I just received 2 brand new iPod Nanos for my kids for Christmas, thought I'd be smart and sync them both now before wrapping them so I don't have to be messing around with them on the day. One synced without a problem, then using the same cable, same computer, same USB port, the 2nd one came up with "The USB device has malfunctioned and Windows does not recognise it" I've tried restarting my computer, unplugging and reinserting the USB. Is there anthing else I can try before returning it? Thanking you for any help.

I have solved my problem, I ended up ringing Apple and got an awesome lady who told me to reset it by pressing the sleep button and menu button together for about 10 seconds and once it actually turned on for the first time the computer then recognised it, so it's all good, :-) Thank you lovely lady!

IPod nano no longer recognized USB device - after almost 2 perfect years

Okay, so I ran about 5 miles last night using my nike+ipod. The ipod worked flawlessly as usual. When I went to plug it in to my computer, instead of acting normal I got "unrecognized USB device" or something similar. iTunes didn't recognize it either. It was charging however. The ipod still plays music, but without being recognized I won't be able to get any music changed on it.
I already tried a couple of things. I rebooted the computer. I plugged it in to another computer (with same results). I switched the hold switch and then held down the top two buttons for 6 seconds, etc. It turns off and back on fine. It plays music fine. The computer seems to know it's there b/c it charges and respondes "USB device not recognized". It just doesn't recognize it anymore.
Please help! Did I sweat too much on it?
iPod nano 1Gb (1st Gen I think) Windows Vista

I got my ipod in May for my birthday and its worked pretty fine up until now. I went on holiday for two weeks to France where I went running everyday with my ipod and it worked fine but on the journey home in the car it wouldnt work and froze. Now it wont charge and is unrecognised on my pc and says that there are no drivers installed for this Device when it before worked fine. I have tried everything that has been mentioned on every discussion I could find and it still isn't working. It's driving me crazy! Could any1 help please? All suggestions appreciated.
Out of curiousity could it be a faulty wire?

How SCCM 2012 compliance function find unknown usb device

As we all know the SCCM get its own compliance DB and can monitor the all device information.
So my scenario is I want to set the USB device with known(permit) and unknown(still permit, but as the admin, I need to know who are using the unknown device).
Any one could give me some advice or procedure what should I do next ?
Asuka from ITECN

Do you want to restrict USB drives? If yes, there is a list of recently connected USB drives available in
HKLM\SYSTEM\CurrentControlSet\Enum\USBSTOR
You can write a Powershell script that enumerates the subkeys there, filters out allowed USB keys (i.e. company provided encrypted ones) and puts the computer into noncompliant state if a nonapproved drive was connected.
If this is about general USB hardware, you can get the list of connected hardware with
gwmi win32_pnpentity | select Name, DeviceID
Of course, there will be thousands of different devices even in a small company, so while you could quite easily blacklist certain devices, building a whitelist will be pretty much an impossible task.

Ipod disconnects when too many usb devices are connected?

i have a gigabyte 7VTXE motherboard, the right via drivers and XP sp3
usb devices where it works:
keyboard, mouse, ipod
if i connect a hauppauge USB tv box or my speedtouch ADSL modem, it disconnects sometime soon after
has anyone else heard of this? annoying isn't the word....

You may be exceeding the total power available on the USB bus. If that is the case, one solution may be to get a self-powered USB hub. Connect the iPod and other devices that are frequently connected and disconnected on-the-fly to the hub. This will also reduce wear-and-tear on the more valuable USB ports on the computer. You can always get another $20 USB hub. Make sure it is the type that has its own power supply.

Unknown USB Device in Windows - VISA does not see it

Hello,
I'm trying to connect my STM microcontroller to my computer using USB protocol and VISA software. When I plug STM USB device into USB port Windows sees it as unknown device and can not find any driver for it. I assume that this is situation VISA was created for. So I want to use a driver wizard to create driver for this device, but VISA does not display it in a device list. I tried to create and install driver for my device as if it was not connected, and installed created driver manually but it did not work.
Is it possible that Windows detects a USB device and VISA can't see it?

It actually depends what sort of USB device it should be. If it is a COMM USB class device, Windows should be able to pick it up directly as serial port, if it is some proprietary USB class, then you either have to get a driver installed and access that driver somehow, or create an INF file with the VISA driver wizard for it and write the driver yourself in LabVIEW using the VISA USB Raw interface. Without a very good description of the low level USB protocol however this last option is a complete no go.
If the VISA driver wizard doesn't display the device in the list then Windows has already claimed it somehow.
