My ipodshuffle g2 recognized as unknown device

when i connect my ipod with my pc(win7) ,the shuffle(G2,1g)is not recognized by itunes or windows,An error box states :usb device not recognized"

You may need to reinstall iTunes. iTunes installs the drivers and other software needed to have an iPod recognized as an iPod. You can get the latest iTunes here

If simply reinstalling iTunes does not resolve the problem, you may need to uninstall first, then reinstall

HP G60-630US Notebook - Webcam is unknown device + USB device not recognized pop ups [update]

My webcam and everything was working fine last night. I even used my webcam on the new yahoo I had installed a few days before. When I got up this morning and turned on my laptop, I kept getting pop ups every 3 minutes stating USB device not recognized despite not having anything plugged. I check out device manager and see an unknown device and Imaging Devices missing. When I try to go into youcam, it tells me that the cam isn't detected.
My laptop is HP G60-630US Notebook PC, Windows 7 Home Premium 64 Bit.
There were no changes made last night. Although after all this I tried removing all of the usb and rebooting, but nothing worked. I am still getting the frequent pop ups. PLEASE any help would be appreciated.
Update: I just ran the Bios update and instead of unknown device, it says USB composite device
This question was solved.
View Solution.

Try this
Use device manager to manually install the webcam driver, Open Device Manager, right click on the unknown image device and select "Update Driver" then "Browse my computer for driver software", then "let me pick from a list of device drivers on my computer" then click the "Have Disk" button, then click the "browse" button, browse to "C:\Windows\inf" folder and find "usbvideo.inf" and select it , then hit OK, drivers should load.

I have the iPhone 3GS and I was updating to the IOS 5 version when at the end of the update it said updated failed. Now my phone is not recognized by my computer or any computer. The computer says it is a unknown device and my phone will not do anything.

Need help finding out what happened to my phone and what I can do. After trying to update my iPhone 3GS to IOS 5 my phone will no longer work and is an unknown device to any computer. It is like it wiped out everything on the iPhone and has no hardware or data on it. At the end of the download and update of IOS 5 it said there was an error during the process and gave me no option but to push ok and know phone is not working. The screen shows the USB plug and iTunes symbol, but computers will not recognize device.

What was the error number? That would be very useful since the following gives actions for various errors.

Try manually placing the iPod in recovery mode to see if that will make the iPod visible in iTunes. See:

Creative Zen 8Gb-Unknown Device!

Creative Zen 8Gb-Unknown Device!? Player: Creative Zen 8gb
Firmware Version: .20.02e
OS: Win XP with Service Pack 3 (Unknown Origin)
Windows Media Player: Version .0.572.545
Motherboard: ASUS P5Q PRO
My problem is that when I connect the player to my computer it is recognized as a Unknown Device and listed as Unknown Device in the Uni'versal Serial Bus Controller of Device Manager.
There is no yellow triangle, there is no section for Portable Devices. It simply registers as Unknown Device.
There is no apparent way to synch with the device. It does not show up in Creative Media Explorer, Windows Explorer or Windows Media Player.
The Original Creative CD installation package does not detect it.
The newest Creative XP installation package from official website does not detect it.
The newest Creative firmware installation package from official website does not detect it.
I have tried several USB slots from front and back (am using back mostly) and short black USB cable (0s long) as well as another USB cable. All USB ports are 2.0.
The player charges normally when connected to the computer and works perfectly for listening to music etc.
Help please! Im poor as hell and will go insane without this player :/

When I connect the Zen, that is where the change happens in the Device Manager trees. It is not recognised as Creative Zen, Portable Device or even a device with a yellow exclamation triangle.
In other words, when I plug in the player, that is how it is represented in the Device Manager trees. As an Unknown Device in the USB controller section.
For your information I have tried this player on 3 other systems.
Laptop A with Win XP/Service Pack 3/WMP
Laptop B with Win XP/Service Pack 3/WMP 0
Laptop C with Windows 7
RESULT IS ALWAYS SAME.
UNKNOWN DEVICE!
The player works fine in and of itself and charges normally when plugged.
Please confirm what are the system requirements for Firmware Version: .20.02e which is the currently installed version on my Creative Zen 8GB

Unknown Device ipod Classic and Windows Vista problem??

Help!! My ipod Classic is not being recognized by my computer. I have read the previous articles and tried the solutions but I continue to get the result "Windows has determined that the driver software is up to date" I continue to get the error noise when I plug the USB in and the Device manager continues to say "Unknown Device" It seems others are having this problem, how do I fix this?

I am having the same trouble with mine, and I can say that it isn't iTunes, I plugged my brothers iPod Nano in and it worked like a charm, but when I plugged my iPod Classic 160g in all it says is it is an "unknown divice". It isn't Vista either as the same thing happens on XP Pro as well, so all I can think of is it is a error on the Classic itself. I just wish someone can help out so that I can use my ipod!!!! Come on Apple!!!! Solve this problem!!!!

Fix for "Unknown Device" when the iPod is connected

After a few long nights, a few headaches, hours and hours of reading, thinking and many toasted sandwiches, I finally found the problem to my iPod not loading. Putting together information I had read here and at many other sites I had a brainwave... and sure enough it worked. I figure this may be helpful to many other iPod users, so... here I am posting my solution. Note though, this wont help all users, but I know I wasnt alone with this issue, and this just might help someone.
Ill list the issue I was having (this may help other people identify their issue to mine) was that the iPod failed to work on windows, and threw a fit when plugged in. Windows did too, iTunes would lock up and the iPod software failed to recognise that an iPod was connected. The iPod had worked on an older PCs before, but it failed to work on my new homebuilt PC. When I first connected the iPod it began to work, transferring and updating.. but then it unexpectedly disconnected the iPod.. and mentioned something to do with an I/O error, the iPod had to be disconnected and it also mentioned something to do with a timeout error and dataloss (or as it put it Data has been destroyed. Thats always a pleasant message to read). Suddenly, half the music on my iPod wouldn't play, it skipped songs until it found a song it would play... really annoying. I tried to format the iPod using the iPod software... buuut it told me that it wasnt an iPod that was connected (Funny that... lol). After the first iPod crash, it would react differently when connected. It would once again pop up with the Found new hardware bubble, Apple iPod..., Disk Drive... ... then iTunes loads... then iTunes freezes... then the iPod disconnects 2 mins later, then iTunes unfreezes. THEN the next time the iPod is connected, it would say it was an Unknown device, and that it has Malfunctioned.
It seems that, oddly enough, my iPod (I own the 30gig iPod Photo) does not like USB 2.0... Im thinking that it must not support some of the device commands the PC is sending to it... Weird though, because on other USB 2.0 PCs it worked fine. (I got the best results out of Dell PCs...). IF USB 2.0 is disabled and slows to USB 1.1 the iPod works a charm... jumped up without an issue in the world. To disable USB 2.0, jump into BIOS as your pc is in its POST stages... this being, when the PC is first turned on and presents a message such as Press DEL to enter setup (or something similar), do so. Then refer to your manual on how to disable USB 2.0, if possible. Apply the changes and reboot. Be sure not to mess around with other settings, it is very easy to mess up your computer if you change settings you are not familiar with.
Other solutions would be to run the iPod via Firewire... if you can get a cable. Run along to your local mac store and see if they have one in stock. Ill get back on here to post if using Firewire solved the issue later.
Perhaps a motherboard BIOS upgrade, or newer drivers could resolve the issue. This may explain to some people why their iPod stopped working overnight after working fine for so long, maybe an update of the sort was installed. Apparently my motherboard already has an update, so Ill test that sometime and post my results as I investigate further, but as for now Im just happy my iPod is working, even if it is taking ages to transfer (25 gigs of music takes awhile over USB 1.1 lol...).
Also, I might add that my motherboard is an ASUS P5P800 with the Intel 865PE chipset. It could be an interesting pattern seeing which motherboards do not seem to be compatible with the iPod at USB 2.0 speeds.
As long as this post was I hope that someone gets some use out of it. Ill post further findings as I investigate this matter further.
Happy iPodding!

hi Jazza!
the best explanation for this that i've seen is that there can be power drain problems in USB 2.0. drop below 500 mA running through the port and everything goes to pot. this may well explain why switching back to USB 1.1 sometimes works like a charm, and also explains why it's important to have the ipod plugged into a high powered USB port rather than a low power port.
i've seen a confirmed case of a USB connection going west after a scanner got plugged into the beast in question ... periodically i see other reports along these lines, too.

Unknown device - ipod nano fine - problem with windows xp and usb root hub

Greetings all. I've seen this question come up over and over again and have been working on it following previous posts and posts on microsoft and hp sites for a couple of days now.
First off - the ipod nano is fine. Works on my son's computer well.
When I plug it into my 6 months new HP Pavilion laptop it says: 'found new hardware' and goes through the process of installing it, says it's been installed, but then shows 'unknown device'. In Device Manager it tells me there are no drivers installed, but when I try to follow the other instructions on this forum to update the drive to USB mass storage device (usbstor.inf), it tells me the best driver is installed and won't do it.
Many seem to have this problem with devices other than the iPod on Windows service pack 2 so I went to the Microsoft forums and they seem just as puzzled. I've updated all my Windows & HP software to the latest possible versions. The problem is definitely in the USB. Once, when I uninstalled the USB device and then rebooted the computer with my iPod still plugged into the port, it found my iPod, correctly identified it, and for a blissful moment I thought everything was fine! Then it reinstalled the USB drivers and made a comment to the effect that I should move the iPod to a USB 2.0 port for more effective operation and the iPod disappeared again.
I have 3 USB ports on my laptop, all are USB 2.0 and all 3 have the same problem.
I've tried all the stuff people have already said on here...does anyone have any NEW ideas? I'm hesitant to take it in for service because it seems to be a software problem that should be fixable.
Thanks in advance for your help and sorry about the long post.

This isn't a solution, but it's something I just tried and it may provide someone additional clues about's going on. I too think this is some sort of USB problem.
I have 6 USB ports. Two of them are USB 2.0. Since I applied the 03-23 update my computer hasn't recognized my nano at all. I would connect my nano and I couldn't get it to show up in My Computer, in iTunes, or on the far right side of the Start taskbar.
I just tried plugging my nano into the first USB port of my USB 2.0 pair and left the second 2.0 port empty. I then rebooted with the nano attached. Viola - I get a "Found New Hardware Apple iPod USB Device" message. My nano is now flashing "Do Not Disconnect." A small removeable storage icon with green arrow now shows on the far right side of the Start taskbar. If I click on it (like you're going to eject it) the note displayed says "Safely remove USB Mass Storage Device - Drive (F:)".
If I go into My Computer, "Removeable Disk (F:)" now shows there. However, if I try to follow Trevor's instructions in another post to "go into My Computer with iPod connected, right click it, wait till the right click menu comes up (could take a few minutes); click Format, . . ." I'm stuck. I do the right click, watch the hour glass and wait for the Format menu to come up but it never does. Eventually the hour glass just goes away. No message, no Format menu. The waiting hour glass just goes away.
My computer isn't as new as yours, but like you I am completely current on maintenance.
I'm going to keep trying . . . If anyone has any ideas, please let me know.

USB Ports - Mass Storage Devices - Unknown Device

Model: Satellite A135-S2276
OS: Vista
I recently tried plugging in my media card reader that I've had for several years now and has worked many dozens of times. Windows responded with an 'Unknown Device' response. I thought this was odd, so I changed and tried each USB port. To no avail the device wasn't recognized. I tried it in another computer and it worked fine.
I began to try two other mass storage devices that I know used to work, up until recently, on the laptop. Both now are 'Unknown Devices'. I now have a strong feeling that someting was wrong with windows vista. So I search around and find methods to force the driver (inf) cache to reset which should reload any corrupted drivers. Tried many methods, nothing worked, same results. I saw that Vista Service Pack 2 just came out, I installed that hoping that it would fix. Nope.
I gave up on it being a software issue after I did a fresh reinstall of the OS and with the base OS with no other software installed same results.
Is there a way to diagnose if the USB is malfunctioning from a hardware standpoint? Is it possible the USB, even thought windows recognizes it, is dead on the motherobard? If so, how do I get this fixed? Motherboard replacement?
Help!!

It sounds like it is working enough that it can recognize that soemthign is plugged into it.
You say you did a fresh install of Windows. Did you use the recovery disk or a retail Windows copy. If oyu didn't use the recovery disk then maybe you are missing a driver. Best woudl be to use the recovery disk. If a USB mouse doesn't work after that then the hardware has an issue. Assuming the BIOS is OK.

Work-around to "unknown device" problem

I found a work-around to the "unknown device" problem, a pain to do, but much less painful than any alternatives I've found so far.
In my case, I can connect my Ipod one time. After I eject it, if I reconnect, I get the Unknown Device error. That's where this work-around comes in.
There is an INF file (a Windows hardware configuration file) in the Windows\INF directory that has a name that will be specific to your computer. Once you determine that file, you need to re-install it. Re-installing it allows the Ipod to be recognized the next time it is connected. These are the steps:
1) Determine the file name on your computer. You only need to do this one time, and then remember the name. Using Regedit, navigate to HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-44455354 0000}. Then do an Edit / Find for "ipod" without the quotes, making sure that "Data" is checked and "Match whole string only" is not checked. It should find "Apple iPod USB Driver" in the "DriverDesc" value in one of the sub-keys. There will be another value called "InfPath". The data for that is the file name for the INF file on your computer. On my computer it is oem51.inf. It will be something like that on yours.
2) In Windows Explorer, go to C:\Windows\Inf and find that file. In addition to "oem??.inf", there will be an "oem??.pnf" (same numbers), which is a binary version of the .inf file. Delete that file, or rename it if you prefer. If it exists, step 3 will not work.
3) Right click on the .inf file and select Install. The computer will chug for a few seconds. The .pnf file should reappear and, more importantly, your iPod should now be able to connect one time. At least it does for me.
I hope that Apple puts out a fix for this problem sometime soon. Meanwhile, doing steps 2 and 3 every time I want to connect is annoying, but bearable.

I would like to apologize for posting this message. I promise that it did work and did seem to be the solution at the time I posted it, but it helps me no longer. My Ipod was recognized several consecutive times after I posted this with no work-around, but then it became an unknown device again, and there it stays, seemingly forever.
I am a highly skilled and experienced Windows system programmer, and this has me stumped. I apologize for any time that my message may have wasted for others. I have also tried every other solution that has been posted here and elsewhere, and none work.
I would recommend that Apple pay me a lot of money to find and fix this problem. Short of that, they should pay someone else to fix it. To have this many fatal problems for so many people should be considered unacceptable. Until a fix is available, I shall just be happy that I got as much onto my Ipod as I did before it became unavailable.

"Unknown Device" shown when I connect my iPhone 4 to the laptop

Hi all,
My iPhone 4 cannot synchronize to my Windows 7. Only "Unknown Device" shown on the "Device Manager" when I connect them via the cable.
The laptop is new and installed Windows 7 Home Premium Edition 64-bit. BIOS is the latest one.
iOS is 4.0 and iTunes is 10.0.1 for 64-bits Windows 7
I do not think the problem is due to the iTunes. Only "Unknown Device" shown on Window 7. I think the iPhone cannot be recognized by the laptop.I tried to connect the phone to a Window XP. It is fine. Likewise, a usb drive is recognize by the Windows 7 laptop.
I have tried
1. update the BIOs
2. Re-install the itunes
3. download the usbaapl.sys
Can anyone help as it bother me for a week.
Thanks very much
Ben

The first thing I would try is to use a different USB port
next I would have my MacbookAir looked at
