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:

Iphone 4s is an "unknown device" and iphone 4 works just fine on my USB Hub.
Okay so for as long as I can remember I sync my iphone 4 using my belkin powered usb hub and all works just fine. Now, since I have had my iphone 4S, my computer will not recognize the device when using my usb hub. It works just fine when pluged directly into a usb on the computer itself. Why does 4 work but 4s does not? Any tips for me to try? Says something like unknown device or not recognized in a little popup in my system tray when I connect it. Thanks.
Win 7 64-bit
ErikI found I was able to get around it too in a different way. I found if you disable the usb hub device in device manager, plug in your iphone or ipad while it is disabled, then enable the usb hub in device manager it works fine. So I actually ended up writing a little script with an icon on my desktop that I just double click when I connect the iphone and it quickly disables and reenables it for me. I am still not exactly happy with this solution either.

HP Pavilion p7-1451 USB 3.0 and Bluetooth drivers for Windows Server 2008 R2
I bought an HP Pavilion p7-1451 so I could have an affordable, yet reasonably powerful machine to put a server software development environment on (I'm a software engineer).
It came with Windows 8, but I needed Windows Server 2008 R2, which I own through an MSDN subscription. I did what I always do in these cases, re-partioned the hard drive, re-formatted, and installed the new operating system.
I have nearly all devices working properly, but it still won't recognize the USB 3.0 ports and the Bluetooth device. I searched everywhere but cannot find anything that will work. Anything from the HP site is targeted for either Windows 7 or 8, and when trying either one of those, it tells me "Your system does not meet the operating system requirements" and MSI does not publish any drivers at all for this particular motherboard (that I can find anyway).
Motherboard: MSI MS-7778 also known as: MSI 2AEO version 1.0
BIOS: AMI 8.12
This is the list of "Other devices" in Device Manager that Windows doesn't recognize:
BCM20702A0
Universal Serial Bus (USB) Controller
Universal Serial Bus (USB) Controller
Bluetooth Device ID: USB\VID_0A5C&PID_21F1&REV_0012
USB Controller device ID: PCI\VEN_1022&DEV_7812&SUBSYS_2AE0103C&REV_03
Windows still doesn't recognize them after allowing it to search the internet.
And I've googled all over the place and I'm not getting anywhere.
Does anyone have any advice?
Any chance this could be related to the BIOS?
I'm not having any luck finding a BIOS download for this motherboard either.
Any help is much appreciated!
This question was solved.
View Solution.Holy crap, it worked!!
My version number was slightly different in the .inf files, but I dropped the last ".1" off the end and that did the trick!
So, the steps were:
Get and extract the driver files:
1. Download the AMD Chipset Drivers file from here:
http://support.amd.com/us/gpudownload/windows/Pages/raid_windows.aspx#2
(choose the first download in the list. It's called "AMD Chipset Drivers")
2. Download and install 7-Zip from here:
http://7-zip.org/download.html
3. Right click the 13-4_vista_win7_win8_32-64_sb.exe chipset file, select "7-Zip", then choose "Extract Here"
Install the USB Host Controller driver:
1. Open the USB Controller .inf file in Notepad from the following location:
13-4_vista_win7_win8_32-64_sb\Packages\Drivers\SBDrv\hseries\USB30\amdxhc\W764A\amdxhc.inf
2. Find all instances of: .5.1.1 and replace with: .5.1
and save and close the file.
3. In Device Manager, right click the first unknown "Universal Serial Bus (USB) Controller" and choose "Update Driver Software..."
4. Choose "Browse my computer for driver software", navigate to the directory in Step 1, and click Next.
5. Accept any warnings and choose to Install anyway...
It should recognize and install the USB Controller driver (finally progress!)
Repeat the same steps above for any other USB 3.0 controllers that are unrecognized.
The devices should now say "Unknown device" instead of "Universal Serial Bus (USB) Controller".
Windows recognizes your controllers now, but not the USB root hubs.
For each of those "Unknown device" entries, do this to install the USB 3.0 Root Hub:
1. Open the USB Hub .inf file in Notepad from the following location: (notice that it's a different directory)
13-4_vista_win7_win8_32-64_sb\Packages\Drivers\SBDrv\hseries\USB30\amdhub\W764A\amdhub30.inf
2. Find all instances of: .5.1.1 and replace with: .5.1
and save and close the file.
3. In Device Manager, right click the first "Unknown device" and choose "Update Driver Software..."
4. Choose "Browse my computer for driver software", navigate to the directory in Step 1, and click Next.
5. Accept any warnings and choose to Install anyway...
I plugged in a USB 3.0 hard drive, and at first it didn't seem to work. I tried another port and still nothin. But after about 40 seconds the drive was recognized and all is well. Yay!
Thank you Paul for your help!
Hopefully this post will help others too.

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 -
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 Lacie Firewire DVD+/-RW
I have a Lacie dvd+/-rw 8X4X12 F A Porsche firewire that my mini won't recognize. Profiler say's its an unknown device. I had it working when I got it this summer, with panther, but remember it being a pain it the harddrive to install.
None of the software finds it including iDVD, Toast, and I tried patch burn today. Nope nothing. Tried the firmware update too. Seems to work OK with windows. I haven't needed it with Tiger and now I do.
Fairly new to Mac so please help.The firewire bus reports it as an unknown device and gives it the standard firewire atributes of 400mbps. I can be more accurate if thats what you need but I am not on the mini at the moment. It is not listed under disk burners.
I have a lot of other equipment running through a router thing(?) including a Hard drive, Audio in/out device, and sometimes a Mini DV. None seem to have a problem. I tried the Lacie solo at least once, nothing. Also, since I posted I tried Lacie's utilities again and still nothing, although the firmware updater mentions a dvdrw in parenthases, but doesn't need to update it.
It's a mini nightmare alright. -
"Unknown Device" appears when ipod is "connected"
So I just bought an ipod yesterday. I took it out of the box and i followed the instructions and hooked it into my usb port on my computer not keyboard. The ipod did not connect and my computer did not even register that anything is hooked in that port. I'm finally able to get it to register about once every 20 times, and when it does it says unknown device and that there are no drivers for it. A message also appears saying a device has malfunctioned and cannot be recognized. The ipod is not charged as it doesnt connect to my pc so i cant even turn it on to follow the 5 r's. What should i do?
Grey text when you look at the content and lock symbol at the bottom of the screen simply shows that your iPod is set to update automatically. If you want to access your iPod directly, play it through your iTunes, connect it to a second computer etc. you just need to change the update method to "Manually manage music and videos" in the iPod preferences. For more detail see this tutorial: Managing content manually on iPod
One thing to be aware of with manually updating is that the iPod also has to be manually ejected before the "Do Not Disconnect" message will go away. Safely disconnect iPod -
I have read through all these articles and cant seem to find a solution to this problem, i have followed all the steps etc and still need help.
when i connect my ipod it comes up as an unknown device and cant be seen in my computer or on itunes, one of my usb sticks also no longer works, and itunes can also no longer recognise or find my cd burner, what the **** is going on here? can someone please point me in the right direction?"Some other usb devices work though" Did you unplug these devices from your computer before you tried to change the drive letter? Use a rear port on your computer?
You might also want to read this: http://docs.info.apple.com/article.html?artnum=305136 Even if no USB Root Driver is available for your computer, read the last section of the article and let Windows replace the USB Driver.
You might also want to try forcing your iPod into Disk Mode (http://docs.info.apple.com/article.html?artnum=93651) and see if your computer can see it. If it can, right click on it and format it (FAT32, not a quick format) then Restore it in iTunes. You might also try changing the drive letter while you are there. If it doesn't see it, try a different cable or try this iPod on another computer. If it doesn't work on another computer, get it serviced. -
Iphone 3G on windows 7 (64bits) shows as unknown device
HP Pavilion tx2500 Notebook PC
ADM Turion X-2 Dual core
Windows 7 - 64Bits
I downloaded the latest version of Itunes and haven’t been able to use since
Every time I connect Iphone to computer, PC recognizes (it shows on Portable devices)
but somewhat shows also in another devices (unknown device) and Itunes doesn't recognize or even shows anything.
I uninstalled and reinstalled Itunes and all apple software (Bonjour, QuickTime etc) about 15 times every way I could imagine.
I extracted files (usbaapl64). I tried to update drivers with no success.
I uninstalled Anti viruses, scanned HD, updated some video/sound drivers
It works on my husband’s computer (another HP)under windows Vista 32bits but it’s not working on mine for the life of me.
I can’t figure it out what its causing the conflict and would appreciate any suggestion
I do not really want to try to jump using the restore since last time I did it I had a hard time to download/update my contacts and settings and ended up having to download MobileMe
Pls helptodays update
It got worse before got better
I uninstalled and reinstalled Itunes a couple more times. I even tried to install a 32bit version since task manager shows Itunes 32*exe.
I finally gave in and restored Iphone to factory settings and then my iphone could only call 911 (emergency calls)
I try to connect again to restore it but it didn't work. I tried the DFU and got a error msg "error-message-0xe8000001"
I researched the error msg and found something about USB2.0. I went to HP site and downloaded an update for some drivers and voila
right now iphone is being synchronized
hopefully I won't have any problems with my contacts like I had last time

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.
