80gb Classic won't sync or charge; "USB Device Not Recognized"

I have an 80gb classic, and a 5th gen. 30gb ipod both with the same issue. I recently rebuilt mine and my husband's computers with new MB's and Processors. I reformatted the HDD's and then installed all necessary drivers and the like along with the newest itunes 9. My ipods had no previous problems and worked like a charm 5 mins earlier.
I hooked them up to my computer and windows came up with an error message saying "USB Device Not Recognized...one of the usb devices has malfunctioned and windows does not recognize it." I put in my other ipod, same error message.
I have tried everything to fix this including, unplugging all usb's but ipod and trying all usb ports, reinstalling usb drivers, switching to 1.1, uninstalling itunes completely and using older versions 5-8, wiping OS and installing vista instead of XP, putting ipod into disk mode, resetting ipod numerous times, among some other things. This error message comes up on all computers in the house (4) including ones that have not been wiped or upgraded.
In addition to windows and itunes not seeing it, it will not charge via USB or wall AC power. The Ipods are devoid of charge now, but when they were full on battery life they still played music through headphones and stereo with no issues, they just won't do anything computer related it seems.
I have not given up hope because I have about 20gb of music and vids I foolishly didn't back up and I want it back. How is this possible that 2 ipods were fine one second then broken the next? Please, Please, Please need help.

I have a Dell Laptop that I've been synching my iPhone with for six months. Now all of the sudden the connection has been lost. I'm having the same problem as you describe and have tried everything I have seen on this forum and elsewhere to fix it, but nothing is working.
I think it is an issue with the driver, but I have confirmed that usbaapl.sys driver is installed in "Program Files," "Common Files," "Apple," "Mobile Device Support" folder. I tried copying the driver and putting it in the main Apple folder, but that doesn't help either. I have tried removing and reinstalling iTunes multiple times, rebooting my iPhone and computer (many, many times). I've tried updating the driver and pointing the USB device directly to the driver, but it does not see it. The strange thing is that when my iPhone is plugged in, it charges just fine. It just won't connect to iTunes or synch with my outlook anymore.
Does anyone have any suggestions? This is a major issue for me as I have to synch calendars to be able to function between work and home. Doubly frustrating that it used to work and now it does not. The only thing that has changed is that I installed printer software and updated iTunes. No other changes to my computer that I am aware of between when it worked and now.

Windows won't recognize my iPod - USB device not recognized

This is really frustrating. So I got a 4gb iPod nano on Saturday, took it home, set it up and everything was going just fine, no worry's. About 4 hours later I went to adjust my songs and it would not come up in iTunes. A little pop-up box said that the "USB device not recognized - one of the USB devices attached to this computer has malfunctioned and windows does not recognize it." After owning my iPod for less than an afternoon, I now have an ipod that I can do nothing to including change the music, charge it, etc. It works normally otherwise, it just won't connect to my computer. I then plugged in my older 256mb usb stick, and the same message, it too does not get recognized by windows. So I then tried a brand new 1gb usb stick that I had and the same result, not recognized by windows. I updated my itunes to the latest one after purchasing my ipod (version 7.4.3.1) and have looked up everything that I can and tried everything I saw to try, but nothing, absolutely nothing, worked. However my usb mouse, usb joystick, and usb printer all still work, but my moniter that has four usb outlets on it causes the same message, if I plug in the cable that connects one usb on my computer to the four on my moniter, windows can not recognize it. When I look in my device manager at the "unknown device" under the usb controller list it says that there is not driver for it, however I know that the drivers are either on my computer or built into windows. Any help? Anybody have an idea about what to do? Is it something in my windows registry has changed because of the new itunes, etc.?

Now that I've had some sleep, I realise I didn't really provide information that may lead to some specific help. Here goes - when I first plugged in the ipod nano (8gb), It displayed the screen it was supposed to - I could see the lightning bolt through the battery icon and knew it was charging. The icon for the ipod also appeared in the left-hand listing in itunes (in the section that existed under Library, before the sections Store and Playlists). This section now does not appear (I can't remember the title of this section, but it might have been 'devices'). In fact, I'm pretty sure this problem started when I clicked on this icon - nothing happened and it disappeared - so did the display on the ipod, which is not just the apple. This means itunes has only Library, Store and Playlist in the left-hand colunm. While I accept that computers do not work on normal logic, this seems to me to indicate that the drivers are fine, the system is fine, my laptop is fine - its the ipod or the usb cord. This morning as I tried again, this time my laptop gave me the option to 'click on the balloon to solve the problem' - let me quote: "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it. Try reconnecting the device. If Windows still does not recognise it, replace the device". Come on folks - one of you will surely know how to fix this (short of me taking the ipod back to the store to get my money back).

Droid Charge - USB Device not recognized

Recently, I was directed by Verizon to reset my Droid Charge to factory settings, since I did that, I can no longer connect via USB to any computer, Win 7 and XP. To this point, I have tried multiple cables, multiple USB ports, multiple computers. On my home computer, I disabled all USB ports and reloaded drivers and still nothing. I have the phone set to "Ask on connection", but still nothing. The phone shows charging, but, I cannot see the device in Windows.
Thoughts anyone?
Thanks

Keven,
Right now I am out of good ideas but for general info when I have the USB Debugging UN-checked and connect my Charge phone I hear two short tones and my XP explorer shows two new folders.
Verizon Mobile F: This one shows info on the phone such as the name of the driver, etc. It says the driver is 1.3.2380.0
Removable Disk G: This one is the removable Disk G that contains all the folders in the phone. The one you are trying to get to.
Maybe, if you have a copy, try to reinstall the Samsung USB driver. It will not hurt to try. You can always reload a driver.

USB Device not recognized Blackberry Classic

I'm trying to connect my new blackberry classic to PC using USB cable. The PC is a laptop with windows 7 64bit. I tried all USB ports available on PC and I tried to install it on another PC with Windows XP. In both PC i get USB Device not recognized error and Blackberry Link cannot connect to smartphone. I need to connect in order to move all contacts from old blackberry to new blackberry. The BB software versions are the following:
- Link version 1.2.4.27
- Blackberry device manager 8.0.0.55
- bbDevMgr 4.2.0.52
-Drive USB RIM 4.2.0.32
- Serial Usb RIM Driver 2.3.0.11
Previously i had installed Blackberry desktop software for OS 7. Before installing the new version, in the last trial i uninstall all software from RIM and cleaned manually the registry.
From what i can understand, there is perhaps a problem with 32/64 bit system driver.
Without a solution to move the contacts and messages from old BB I will change the phone to another version/supplier. I spent already more than 1 day trying to do this...
Thanks for the support

I have Windows Mobile 6.0 on my Treo 750, Windows Mobile Device Center on my laptop (Vista OS), and Outlook 2003. When sync is established there is no problem with Outlook 2003, but there is a problem with recognizing Treo by my laptop. Also (probably) there is a problem with the connection cord (I have to move slightly USB couple of times inside a port in term to start connection)… It’s a minor but annoying problem.

"USB Device Not Recognized" Bubble/ Ipod won't connect to Windows

Whenever i connect my ipod to my computer the ipod goes to "do not disconnect" and a bubble pops up on my computer saying "USB DEvice Not Recognized" i have switched it to all of my usb ports and unplugged all usbs except for my mouse at the same time. this happens 95% of the time. my ipod does charge while connected and it has only connected to itunes once in the past 2 weeks. im not sure if it is itunes because it started around the time i updated to itunes 7. since it is a windows bubble though i think it is a windows or ipod problem and not itunes. i have a dell that isnt great but works fine.
thanks for any help.
... Go TTU!

Make that two idiots. My roommate got a Sansa and I decided to try out the cable. Nothing happened. Now suddenly my nano isn't recognized by my computer. I'm glad I read your post, now I can stop looking high and low for a solution. Until this happened it worked good as new.

Ipod 7th generation. bought it 3 days ago. no problem then but now won't turn on. I keep getting a usb device not recognized (and i keep changing ports to no avail). what to do?

Try leaving it plugged in and then restart the computer.
If you are on Windows this link may help but it is a bit old.

Is the iPod Touch specifically stated as being compatible? Have you tried to perfrom a hard reset of the iPod with it still connected? To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.

USB device not recognized with 160G ipod

I did absolutely nothing different, no updates, no hardware upgrades, didn't drop my ipod, suddenly when I plug my 160g classic into my computer vista just says "usb device not recognized" and I cant do anything. I can charge my ipod on my radio dock but that's it. I've tried plugging it into 2 32bit vista desktops, 1 32bit vista laptop, 1 XP laptop, and 1 64bit vista laptop and they all give me the same message. I've tried many different usb ports, and 2 different cables, nothing works. Help please!

I don't know if this will help you, but I was having the same problem and when I sent it off for repair...they sent it back saying it was not under warranty b/c it had liquid damage, etc...bunch of BS! Anyway, I called tech support to do a little venting and the technician said i should try uninstalling itunes, Apple updates, and quicktime which will not mess up your library, etc. Restart and then download newest version of itunes from apple website which i did. I restarted again and then connected IPOD 160G to it and to his credit...Ipod started to connect and be recognized in itunes. I had to restart one more time w/ ipod connected so it would all sync, but bottom line...it worked. Apparently, the itunes/quicktime updates can screw w/ these new ipods causing problems. Why they just don't come out and say that or at least suggest this line of solution when they send an ipod back unrepaired...i don't know....very poor cust service on that end of it. Hope that helps.

My computer no longer recognizes my 7th Gen iPod Nano. "USB Device not recognized." What can I do to fix this?

Hi!
So here's what happened: My nano has been working just fine. I plugged it in this morning to my computer, and it automatically turned on, but instead of charging, it went to play music. I turned it off. However, it did not switch to charging mode. So I unplugged it, and then I plugged it back in. "USB Device not recognized." My iPod won't turn on anymore, and my computer simply does not recognize the nano.
It may have gotten slightly damp yesterday as it rained a bit when I was walking home (though I kept it covered). When I got home, it proceeded to work for another two hours after that--then I turned it off. And this morning? It doesn't work, as described above.

Try cleaning the connector on the bottom of the phone. Use a magnifying glass to see what is stuck inside, a dry toothbrush and/or wood or plastic toothpicks (nothing metal). If that doesn't resolve the problem your phone is broken.

Zen Vision M...USB Device Not Recognized

My Zen Vision M 30g?is no longer recognized by my computer. I get the following message: "USB Device Not Recognized: One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it." I haven't changed anything on my computer (Windows XP Home Edition SVC Pak 3), so I don't know why it would not recognize my player all of a sudden. My zen still plays and charges using the portable charger, so it is still usable; however I can't change anything on the player. So far I've tried disc clean up, changing USB ports and plugging it into another computer (got the same message). I haven't seen anything on the bulletin board about "malfunctioning." Does this mean my zen is done?

Thanks. I keep getting directed to that knowledge base page, but it is not addressing my problem. My computer immediately tells me that the device has "malfunctioned" and the computer does not recognize it. I only have the usb cord that came with the zen, so I don't have another one to try. I love my zen and have staunchly defended it over the years vs. an i-pod. However, this is my 2nd one in 5 years. (The first one fried itself, but fortunately was still under warrantly.) Sadly, I, too, am considering moving on. I onlyreceived generic help fromthe Creative SupportTeam (who ultimately told me my zen is "unrepairable" when their one-size-fits-all solutions didn't work).Since there seems to be an overwhelming # of people experiencing similar problems, maybe the time is right to make the change, especially since an iPod classic 60 GB (7th Generation) is quite affordable these days.

"USB device not recognized." "The connection between your device and the desktop could not be established. Please check your setup and try again." Tungsten E2, Outlook 2007

Hi,
I am running XP SP 2, on a Dell Vostro 1000, Palm OS Garnet v5.4.7 on a Tungsten E2. I have worked though issues relating to synchronization, Outlook 2007, Docs to Go, etc., in the past. Thank you board members!
Once I worked thru all the initial problems, my Tungsten E2 was sync' ing beautifully to my laptop until a few days ago. There have been no changes (I know of) to the configuration, but now I receive "The connection between your device and the desktop could not be established. Please check your setup and try again." On the laptop I sometimes get "USB device not recognized." I am unclear why I get the PC message sometimes and not others.
I have tried the following: (not necc exactly in this order)
Double checked Hot Sync Mgr settings: Local USB (ver. 6.0.1)
Reset the Palm (multiple times)
Rebooted the laptop (multiple times before and after the Palm resets)
Went to Support Libraries including http://kb.palm.com/SRVS/CGI-BIN/WEBCGI.EXE/,/?St=57,E=0000000001060189973,K=9550,Sxi=3,Case=Obj(3695...)

Followed the steps in "Start Here" found at http://forums.palm.com/palm/board/message?board.id=windows_hotsync&thread.id=26057
Moved Backup directory as per a post on this forum
Looked for a deleted a file called "Graffiti_ShortCuts_____________" per a post on this forum
Followed the steps in HotSync troubleshooter guide you can run through located on
http://kb.palm.com
Went into Device Manager - found it shows no yellow ! 's
Followed Device Mgr Troubleshooter - went all the way thru with no solution
Tried all four USB ports - the PC's bell-like tone does not sound when I disconnect or reconnect the Plam's cradle like it does when I conn/disconnect other USB devices -I think that is a clue. ...?
Cleaned the Palm's contacts (and cradle's contacts with a old, dry toothbrush)
Read all the posts under "USB device not recognized."
OK, I'm at a loss, can anyone help me? Many thanks in advance!

Post relates to: Tungsten E2

Hello!
Using a cradle with the Tungsten E2? Tried bypassing the cradle and just use the hotsync cable? Tried a different computer yet? Somehow, the PC is having problems getting a signal from the device. I assume you have the laptop charger plugged into the laptop during this? Not going through a docking station or port-replicator.
One crazy thing you can try is unplug the charger from your laptop, remove the battery from the laptop and leave it out for like 10mins and put it back in and reboot the laptop. This should not cause side effects but still contact your OEM to make sure that nothing else is needed after leaving the battery out for extended period of time. Keep me posted.

HT201210 USB device not recognized

the message USB DEVICE NOT RECOGNIZED keep showing and i cannot sync my ipad to mu computer. Its charging for more than 8 hours for less than 50% battery life. What should i do? its not even a year old.

You should use the charger that comes with your iPad. USB port usually do not supply enought current to charge battery.

IPad I: USB Device Not Recognized

My iPad is not recognized by my computer (USB Device Not Recognized) or iTunes. The cable works fine and all other iPods are recognized. I can't update my iPad or sync. I have tried uninstalling/reinstalling/verifying other components etc...everything that I can find recommended for this type of issue. Are there any other possible alternatives or could this be an inner component of the iPad that requires repair? Naturally, this occurred after the warranty expired. Any help will be appreciated.

Most USB ports n computers do not provide enough power to charge an iPad. You need to use the wall charger and plug that into a known good wall outlet.
The iPad will not show up on your computer like a hard drive. Start iTunes on your computer and plug your iPad into the USB port on the computer. You should see the iPad recognized in iTunes.
