No Driver Found/iPod is an Unknown Device

Hi,
I recently installed the updated Apple software and ever since, I haven't been able to sync up my ipod to my computer. The ipod can be charged, but it isn't found on Windows or itunes. I've tried everything from the Apple Website to fix the problem except completely wiping out everything on my ipod. I've deleted itunes 7.0 and reinstalled itunes 6.0, I've plugged it into different working usb ports and I've checked for viruses on my PC. Still no luck. I've never had this problem before on my 5th Gen ipod and was wondering how I can find the driver to fix my problem.
Thank you for your help,
Dennis

My iPod is recognized by my work computer using the same cord I use to plug it into my computer
Thoughts or suggestions?
Well if it works at work, but not at home then the iPod is fine but something is wrong with your setup at home, could be USB hardware/firmware/drivers, USB drivers for other devices (I have a multi-fuction printer with a memory-card reader which interfers with all other USB drive connections when turned on) or the iTunes installation. You could try system restore going back to the last time it still worked properly which might help if it's a driver issue. Your best bet might be a clean install of Windows. Since that generaly takes time to organise & you should backup your data first I'd suggest you buy a nice big external hard drive, backup up all your data on to it, including your iTunes library & music, take it to work, and sync your iPod from there until you get around to cleaning up your machine at home.

Driver for IPOD as a storage device on a windows 98

Is there a driver that will enable me to use IPOD only as a storage device on a windows 98???

IBook won't load Firewire drive; "unknown device"

That's the summation via System Profiler. It's a SmartDisk Firelite enclosure but I swapped the old 40 GB drive that failed for a new Seagate Momentus 80 GB drive. My G4 dualie recognizes the new SmartDisk setup fine. It loads immediately and I was able to access via all the utilities. Transfers work well.
But on the 1.33 iBook the green light appears on the SmartDisk enclosure, but no threat of loading. Only System Profiler identifies something, "unknown device" with 400 capability. When I remove the firewire cable, System Profiler doesn't see anything.
I had no trouble with the SmartDisk prior to the old drive failing. It worked perfectly on the iBook. My firewire port appears to be okay, since I tried Target Disk Mode with the two computers and it worked well.
Any suggestions would be greatly appreciated. I Googled and found many issues of "unknown device" related to firewire drives, but none that seemed to precisely fit this case, a drive that was recognized on one computer but not another. Both are running 10.4.11.

I'm still baffled but tonight I found an acceptable alternative, a Macally 250 Firewire/USB enclosure that I had in my closet but never used previously. The Seagate drive loads on both the dualie and iBook using that enclosure, which is bulkier than the SmartDisk but right now I don't really care.

Unknown Device!!!! HELP!!!!

I already have the software installed, and I know that my usb ports work because i've used them in the past with other hardware. I just bought my ipod today, and when I plug it in a little symble thats the same as the one beside of the usb port pops up, when clicke on, it says unknown device. I can't even access it so much as to format it. Any help whatsoever would be greatly appreciated. I don't want to have wasted this money. And I'm on a PC btw.

I've got the same problem... I'll list all the details..
I have an iPod Photo 30 gig.. worked fine on my old computer, plugged it in and it was great, not a problem in the world.
I then put together a new PC, 3.0Ghz P4... and installed windows and put it all together again. I restored my database from my old iTunes library. When I connected the iPod it worked... and began tranferring and updating.. but then it crashed.. and it mentioned something to do with an I/O error and that the iPod had to be disconnected, and it also mentioned something to do with a timeout error.
Suddenly, half the music on my iPod wouldn't play, it skipped skipped skipped... 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 working away at the problem I decided to format and try the iPod again... still no luck, and its really getting to me.
What happens now... is, you connect it, it says Found new hardware... Apple iPod... ... Disk Drive... ... then iTunes loads... then iTunes freezes... then the iPod disconnects 2 mins later, then iTunes unfreezes. Now it says the iPod is an unknown device, and that it has Malfunctioned.
This is really annoying me. Ive tried to download updates from Microsoft, but I cant. Theres an error in the validate thingo, Ill have to call them sometime, but thats irrelevant. Does anyone know a fix? Or... someone mentioned the firewire works... I have a firewire card... where can I buy the Firefire cable from? And... how can I contact apple for help, if I need to?
Annoying though, because the USB method worked like a charm before this. BTW this iPod still connects perfectly on other pcs... but it doesnt have the music library I want lol...
Sorry for the long post, but I figure the more detail the better. Any suggestions would be greatly appreciated. Thanks a heap!

Unknown Device Error (0x0C, 0x00.) When trying to Burn

The past few days i've run into problems trying to burn from my Mac Book Pro.
In DVD Studio pro i get the " Unknown Device Error (0x0C, 0x00.)" when I try to burn from the burning on the computer.
I even tried burning from an external Lacie drive and I get the "Unknown Device Error (0x30, 0x05.)
I've cleared up hard drive space i have 5 gigs free. And I've tried restarting many times. I haven't run into problems like this before.

Hi
That can be caused by bad quality media. Read here about * about quality media * and try allways to use first quality group.
Besides that, DVDSP is not the best burning software at all. My prefered workflow is * Creating Disc Image in DVDSP * and burning it with Toast or Disk Utility.
Hope that helps !

GTM785-E45 and 4 unknown devices.

Hi all.
(Not sure if this is in the right spot, but...)
Had a system poo on me recently, so I bought this board, installed xp on it (upgraded to sp3) and have most everything back to normal, but now I have these 4 unknown devices that keep showing up in device manager. They're under:
PCI bus
> PCI standard PCI-to-PCI bridge
-> Microsoft UAA Bus Driver for High Definition Audio
--> Unknown device (4 separate entries of this, all with the whole question mark/exclamation point deal)
I've tried installing/uninstalling the HD Bus driver, the Realtek drivers, and all the simple and obvious things that I can think of, but they just won't go away. I've also done almost everything listed under this topic:
( https://forum-en.msi.com/index.php?topic=115476.0 -except for the registry editing, which I am going to try tonight ) as well, because it sounded almost exactly like my problem. However, nothing.
I should also point out that there is another Microsoft UAA Bus Driver for High Definition Audio listed as well, with the Realtek High Definition Audio beneath it. And that I do, in fact, have sound. I'm just mystified by these 4 unknowns.
specs:
PROC - AMD Phenom X4 9850 Quad Core 2.5ghz
MOBO - MSI 785GTM-E45 (says MS-7549 Ver 1.4 on mobo)
BIOS - A7549AMS Ver 8.8 12022010
PSU - Rosewill RD500-2DB (Model No. SL8500BTX 500W)
VID - Galaxy Nvidia GeForce GT430 1GB DDR3
RAM - Corsair 2048MB PC6400 DDR2 800MHz Dual Channel
HDD - SATA - Seagate 160gb, Seagate 500gb
HDD - IDE - Western Digital 45gb (Install drive)
DVD/RW - Lite-on 24x / Lightscribe (can't fully remember the details off hand)
WinXP 32bit SP3 v5122
(I think that's all. If I'm missing something, let me know.)
Thanks in advance!
Ryan

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.

This is the message that i get when ever i plug in my ipod touch to my computer. the computer is running on vista. i dont know what to do, because i tried to follow the steps suggested, but it didnt work, the computer said that it couldnt find anything and to check with apple for some driver software. HELP!!!

The iPod touch and iPhone do not use the same type of USB drivers that other Apple devices use. They both require Apple Mobile Device Services to be running. Using this tech article as a guide, you can easily fix this: http://support.apple.com/kb/TS1567

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!!!!

Ipod Touch not being recognised/unknown device

Ipod Touch not being recognised - help!?
It says it's a code 43 - Unknown device/device not recognised. Doesn't sound good.
Tried all of the things the itunes website suggested such as of course turning it off and on again, restarting services, reinstalling itunes. I know from experience that when you take it in to the shop they want to charge you almost as much as you bought it for to fix a minor problem. Thanks

Hi,
Reinstalling iTunes *will not* erase your music library.
As a matter of course I do, and in fact Apple recommend that you back up your music library, there is an option to do this under "File" in iTunes. It is really quite sensible to have your purchased and other music files saved elsewhere as well as on your main hard drive, it can save a lot of time and hassle.
Good luck,
Dud.
