Laptop device not recognized

Hp Pavilion dv6725us
s/n CNF751066W
p/n KC301UA#ABA
I am running Windows Vista 32 bit
The following devices DO NOT show up on Device Manager:
·         DVD/CD Rewritable DriveAD-7561A
·         HP Webcam
Also the following devices ARE listed on the Device Manager, but they have a b/w question mark or yellow triangle w/ ! next to them. Driver updates are unsuccessful. I do see the following status messages:
·         Base System Device( Location PCI Bus 2, Device 5, function 3)
·         Base System Device( Location PCI Bus 2, Device 5, function 2)
·         Base System Device ( Location PCI Bus 2, Device 5, function 4)
·         IEEE1394 Controller( Location PCI Bus 2, Device 5, function 0)
·         SDA Standard Compliant SD Host Controller ( Location PCI Bus 2, Device 5, function 1 - The device cannot start Code 10)
I have restored Drive C from the Drive D (twice)
I have installed another AD-7561A drive (no difference)
I have installed all Windows updates
I have used the Windows Fixit for DVD/ CD problem
I have checked the registry to see if there are upper or lower filters to be removed from the DVD/ CD drive.(There were none)
When I load a DVD, I hear whirring , but then nothing happens. I cannot boot from the ATAPI DVD/ CD drive.
Otherwise the laptop boots to Vista with no other problem.
WHAT ELSE CAN I DO?

Here is the key:
"I cannot boot from the ATAPI DVD/ CD drive"
Either the drive is bad or the port on the motherboard where the drive plugs in is bad.
The AMD versions of the dv6000 series have a checkered past and are known to be prone to motherboard failures.
The base system device and SD Host should be the card reader.

The firewire (ieee1394) should "just work" since that driver has been in Windows since Windows 2000.
Be sure to install the chipset driver:

TS1369 Hello! I have an Ipod Shuffle 2nd Generation and it is not recognized by my Windows 8 based laptop. An error message of 'USB device not recognized' is shown. I have the latest ITunes version installed, and tested the dock in other pc's.

Hello!
I have a problem connecting my Ipod Shuffle 2nd generation to my Windows 8 based laptop. The computer doesn't recognize the Ipod and issues an error message saying 'USB device not recognized'. I tried uninstaling ITunes(latest version) and all other Apple software and reinstaling it back again, checked my USB hubs in the 'Device Manager' section of the Control Panel, you name it.
I could really use some help solving this.
I've turned to the troubleshooting section in Apple Support but it has nothing concerning situations in wich the device isn't even shown in the 'My Computer' folder.
Help a brother out, will you???

Found a solution in another forum http://en.kioskea.net/forum/affich-63733-ipod-not-detected-on-computer (a few posts down).
It was for an IPOD so you can see those details in the link.
Found how to reset a shuffle and inserted it into these instructions - did not have to follow his last steps.
- Turn off computer.
- Plug Shuffle into usb.
- Then you must reset your shuffle
To reset iPod shuffle:
Disconnect iPod shuffle from the computer (if connected).
Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible
Disconnect iPod shuffle from the computer (if connected).
Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible.
- Start computer and it should install the usb driver for the ipod automatically.
- Your i pod will say do not unplug so don't. then open itunes and it will be there.
I did not have to do these thing below – did not get error message and shuffle was displayed in Itunes. / LMc
Just remember to not only eject ipod from itunes but stop usb.
Go to the program icons near the clock and right click the usb icon and "safely remove hardware" will appear and click it.
Stop it and select "apple ipod".

When I connect.. sometimes it says Device not recognized or malfunctioned!

Hi. When I connect my ipod to any microsoft device, sometimes my ipod doesnt connect. I cant charge it, or restore it as it behaves like a useless piece of plastic.. I get a yellow bubble 'Device not recognized or has malfunctioned'
This problem is bizarre! I cannot find anyone who actually has a solution for this problem! Apples standard answer is for me to reinstall my drivers or update itunes or windows. Done it. No solution yet.
My ipod works fine.... sometimes. Its a completely unpredictable problem. Ive googled this problem and so many ipod classic owners have asked.. solutions ive tried: the 5r's, updating drivers, It managed to connect once, but now it wont. My ipod normally works fine on my PC, XBOX, laptop and Mac.. but sometimes, unpredictably, it wont be recognized by anything apart from the mac. For a month it would not connect at all and I took it in to an Apple store where they told me it works fine. Its not my PC.. its up to date, and theres no reason why it doesnt work on my XBOX because some times it does.. last night it did, today its broken again, I suspect tomorrow it may work. This is SO frustrating!!
I have alot of experience in PC's and normally I can solve a problem by process of elimination, updating and reinstalling, but in this case.. everything seems fine. My only idea is that maybe its my Sync cable?? Which also makes no sense because it generally connects fine on the mac - and, why would a sync cable be unpredictable.. surely it either works or it doesnt. HELP PLEASE!!
Nick.
my email is: [email protected]
my serial for my 80g classic is 8K819CPKYMV and is under warranty until May 2009, i bought it in August this year.

there is a good chance that this can be related to bad contact in USB lead.. e.g not enough power from IPOD to PC so that pc cannot recognise it. Where I work I get alot of USB devices on pc's that are not recognised and most of the time it is the connection to the device that is not good enough because the flat end of the USB adapter has been gradually bent over time just slightly and now contact is not good. It can also be todo with drivers or If you are using it through a USB hub.
so if it is not working through USB hub try direct. also try in back of PC as these Ports or direct access to main board to pc and would be less trouble some if there was a voltage loss from mainboard in pc to front of unit.

USB Device Not Recognized on Windows 7 - USB mouse

I have a 4 week old Inspiron 1545 with Windows 7 Home premium that has developed an error: USB errors while trying to install a Microsoft USB mouse on this Laptop. Interestingly, my Microsoft USB Mouse installed perfectly first time and worked for about 2 weeks, and then failed. In looking at the system restore points, it tells me that there have been two driver updates to the USB environment since the unit was shipped from Dell. I wonder if an automatic update from Microsoft has somehow inadvertently updated or replaced a Dell factory driver.
Two nights ago I spent 45 minutes with Dell tech support doing remote control bug fixing on this laptop. They werent able to fix it (in the time allowed). They downloaded at least one of their newest drivers onto this machine and rebooted it - and they seemed pretty savvy - but still not working. So I went ahead a did a system restore to a point about 10 days back because I could see that a USB driver would be affected (as shown in the system restore menus), and I would like to compliment Microsoft on this very cool functionality!
At this point, I've unplugged the USB mouse , used the Device Manager to delete the 'unknown device', and done a system restore back to what I suspected was a working point. But still getting a 'Device not recognized' warning every few minutes, and still don't have a working mouse. I don't want to have to do system restores back to pprevious dates, although I suspect this is one solution.

Hello,
I just wanted to let u know, I had this same issue for about 2 weeks. Basically what happened was a bad install of my AMD Chipset drivers. When I attempted to upgrade, the install didn't go all the way through.
I then restarted my system, and BAM! No Mouse or Keyboard functionality thru USB.
Even when I went into SAFE MODE the Mouse and Keyboard were not functional. The only time they worked was when the computer first attempted to start, BEFORE windows loaded.
So, this means that your issue is a software problem.
I thought it was some other software that I installed, and ran a restore session, but that wasn't the issue. Still no functionality.
I even tried removing my CMOS battery, to reset it, since some people said that had solved their problems...Still nothing.
I then read other forums around the web using my Android phone to try and find a solution, only those solutions were no help.
I was also advised to run: MSCONFIG and Hide all Windows programs and then stop every other driver, source from loading (of course if my mouse and kb worked, I would have tried that).
I had even read that because I was using USB, that I should try using a PS/2 Mouse and Keyboard connection.
It took me 2 weeks to get the correct PS2 adapter that worked, which would essentially allow me access to my system again...
I Purchased a USB A Female to PS2 (MDIN6) Male Adapter (for Mouse) from http://www.SFCable.com
This my friends, was a lifesaver. I only have one PS2 port on my system, so I used my mouse to try every option I had previously read about. Of course you cannot type because the keyboard doesn't work, so you need to know the location of the folder where
the programs you are trying to run are.
So, a little after I got back into my system, and I closed down all programs, the warning screen came up that ALL of my USB Ports failed and could not be updated. I even Uninstalled every last USB port from the System Properties and restarted, and still
that didn't work.
I had forgotten that during the time when this problem arose, there was a failed install of my AMD chipset drivers, so luckily I had not deleted the source file and I tried to reinstall, and VIOLA! I'm back up and running and my USB ports are restored
and everything is working!
I hope this solution is able to help other people out there.
Thanks,

"USB device not recognized" when ipod plugged in???

(ipod mini 4gb)
When I plug my ipod into my laptop I get the message: "USB device not recognized." It says the device has malfunctioned!!! If I click on this error message it says my ipod is an unknown device and no drivers are installed for it???
It was working fine until a few days ago. If i reset it I can charge it up but that's all, it still does not appear in itunes or on my computer.
I've tried eveything on the help website but nothing works! Can anyone help?!
patriot 3050 Windows XP

ok my question is do you have a mac or windows based laptop
here is why and what happened to my ipod mini
my ipod mini was connected to my macintosh charging while i was using my imac and it came up with a system update 10.4.3 i installed it and finished installing it and afterwards my apple wouldn't recongnize my ipod mini or even display it one the screen i found out by myself that when the apple update got to the end of the update it installed new hard drive drivers but also installed the drivers on the ipod mini which locked out the mini's internal hard drive and my mini then stop responding it would play music and charge but wouldn't connect to the computer
so what i did to fix it was this
i went into utilites in mac os x tiger or any version of os x has this and selected disk utility you will notice that the ipod will appesr in disk utility but not on the desktop this is due to a recent system update driver that isn't compatible with the internal drive on the ipod mini so in disk utility just select format the drive in a mac os partition standard works the best it will then format the ipod and the ipod will apear in the desktop again but not as a ipod let me explain when you format the ipod using the disk utility it formats and even erases the firmware of of the hard drive on the mini so when you are done formating the ipod run the ipod updater to reinstall the ipod's operating system and presto your ipod will now work again
warning: i don't know how to fix this on a ipod in windows so if this is a windows based laptop you need to find someone witha macintosh to do this with sorry

IPod nano 3rd Gen 8G "Device Not Recognized" on 2 diffrent computers...

I have the latest versions of iTunes on both a Windows XP service pack 3 computer and Windows 7 Laptop. I've tried multiple cords but both computers tell me "device not recognized", I've uninstalled and reinstalled all drivers. Done a reset and Disk Mode reset on my iPod. Haven't droped it or damaged it in anyway since i've connected it sucessfully to my computer last time. Will charge on a wall charger, car charger and dock. Tried connecting friends iTouch and it was registered by Both computers.
And ideas on a fix other than the $100+ apple wants, I'll just got buy a new MP3.

- Try another cable
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.

USB Device Not Recognized (&IPOD WILL NOT TURN ON)

I have had an iPod Shuffle G2 for 6 months now with no problems until today.
It went flat when I was at my friends place so when I got back to my mums I plugged it into my laptop and it told me "USB Device Not Recognized One of the USB devices attached to this computer has malfunctioned and windows does not recognize it" I thought there was just a prob with that port in my laptop, so I put it in the other one. So I though Ill wait until I get to my nan and pops and put it in there computer which is where I sync it. Same problem in both ports. Except on this computer the orange light is on but doesnt flash.
Now my iPod doesn't turn on at all..
Which is fantastic..
Help yeah?
My mum is gonna kill me.

thank you for you help so far. I am very frustrated with this thing. I have been trying to correct this problem for hours.
I will try to disable virus protection. but I will have to enable virus protection again. what should i do?

"USB Device Not Recognized" Message when connecting iPod Nano

I get the following windows pop up when connecting my son's iPod Nano
*"USB Device Not Recognized"*
*One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.*
I have successfully connected this device to this computer before so I don't know what has changed.

This did not work for me. I have a laptop that was running Windows XP, and it had no problems recognizing the iPod. I was having problems with XP, and rather then reinstall XP, I did a clean install of Vista. I did a settings transfer, so the new install of iTunes came already configured--I mention this since I don't know if it was a factor.
When I plugged in the iPod, I got the USB Device Not Recognized. The usbstor.inf file did not fix the problem. However, the solution at http://www.winvistabeta.com/groups/275128/ipod-usb-device-not-recognized/message .aspx did fix the problem. Do this:
Reset the iPod:
1. Unplug the iPod.
2. Turn the hold switch to HOLD and then back to off.
3. Hold the Center and Menu buttons for 6 seconds until you get the Apple logo when you release them.
4. Plug in the iPod. It should now be recognized.
This worked fine for me the first time. Thanks! Jack

2G Nano-USB Device Not Recognized message

2G Nano has been sitting for months. Decided to use it as a backup. When connected to computer (tried on 4 different computers running iTunes) I get a "USB Device Not Recognized" message. It shows up in "Device Manager" as an "Unknown USB Device" not an "iPod". Have performed the required 5 Rs and it still will not work. Any help would be greatly appreciated!

Usb device not recognized on shuffle

i have a belkin usb 2.0 device with 2 ports. it is plugged into my ibm thinkpad laptop. the mouse works fine in both ports -as does a photo scanner. but for some reason, the ipod shuffle is not recognized - i keep getting a green blinking lite and a message that says "usb device not recognized". funny, because the shuffle worked fine the other week when i installed all the software after purchase. i've updated windows software and reset the ipod. i've read elsewhere that some people have had the same problem - and that it was a malfunctioning usb port on the ipod shuffle. if so, what a piece of junk. maybe i just need to call tech support and ask for a new shuffle - i don't think that downloading the updater, etc. will help. any suggestions? thanks.

If it's working with other computers (using the same USB cable to connect the shuffle), then the problem is probably related to your computer.
If you connect something else to the same USB port (like a USB flash drive if you have one), does it work?
If you are using a USB hub to connect the shuffle, be sure to try a port that is directly on the computer. And try more than one port that is on the computer.
Also, it may be helpful to know some other details, such as type of computer (Windows or Mac) and the version of OS.
Since this is a laptop, if it has a main battery that can be removed, you may want to try disconnecting it from power and removing the battery. Leave it that way for a new minutes. Then, put the battery back, start it up, run iTunes first, and try the shuffle again. If there was a problem with your USB ports, that may correct it.

"USB Device not Recognized" when shuffle is plugged into computer

Everytime I plug my shuffle into my Dell laptop it comes up with the message "USB device not recognized". The shuffle doesn't show up in my computer or itunes. I've done some of things that it says to try, but I'd really like to get this fixed and get my shuffle working. Typically when I plug it in, it blinks once, yellow/orange, and then no more, and the notice comes up on the computer screen. If this makes a difference, the shuffle worked fine until last summer when my hard drive crashed. Upon installing a new hard drive, the shuffle began to not work/sync with my computer as it had been before. Any suggestions on how to get my shuffle working again? Much appreciated!

"USB Device Not Recognized" error when I connect iPod to my PC

I have a brand new 5th gen (I think) iPod.
I have been able to connect it successfully to my home laptop, download music to it and play it so I know the iPod works per se and the cable is ok too.
Now at work (where tons of my music is) when I connect it to my PC here and I get a "USB Device Not Recognized" error pops up from my taskbar. When I click on the message it pops up a "USB Device Not Recognized" window which displays a list of USB ports, and shows "Unknown Device" for the one where the iPod is connected.
I think its probably USB1.something as opposed to USB2.0 but from what I understand that shouldn't matter.
Can anyone suggest anything ?
I've tried the 5R's as far as I can, and I read through this thread:
http://discussions.apple.com/thread.jspa?threadID=500559&tstart=15
but there didn't seem to be anything conclusive.
Thanks for any help,
Jill

First make sure the latest iTUnes is installed on this work PC, IF your allowed to install things on it, the latest iTunes version is 6.0.4.2 and can be downloaded from the apple site (Hit iPod+iTunes tab at the very top of this web page)
Another thing is what version of windows is the work PC? Is it windows XP Windows 2000 Or windows Me 98? iTunes will only run on XP and 2000

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.

USB device not recognized in Windows 7?

I have the strangest problem I've yet to encounter with my computer.
As you may have guessed from the title, I am constantly getting the message displayed. Any fix that has been suggested has been unhelpful or worked for a bit until my computer restarted again (I'll get to that)
First off it started when I noticed my mouse pointer was acting very weird, it was just a vertical line of dots. A forum said an easy fix to the problem was to update my GPU drivers, which I needed to do anyway. So after an update to the GPU drivers
I log into my computer (which is password protected, this is slightly important to remember) and I try to go to youtube. I click down at the start menu to type in chrome and nothing appeared. I was able to move the mouse around and click on things
but I was unable to type anything.
Luckily for me I have a laptop as well so I checked for any solutions on my laptop and they said that it was a problem with the model of my keyboard specifically This was odd to me considering most of the problems happened OTB for the keyboard and not
a month after use, plus I was able to plug it into my laptop and it worked just fine. When I plugged it back into my desktop it gave me the same problem: I couldn't type anything, I also noticed the little pop-up informing me that the USB device was
not recognized. "Well, great, time to get my backup keyboard," I thought to myself. Except, that was not the case either. I plugged my backup keyboard into every single USB port on my Computer Tower, even going so far as to unplug
the mouse. Absolutely nothing was working. I constantly restarted my computer and each time got the same problem; I'm able to type in my password to log in and then a few minutes after that the USB device stops working. Sometimes after plugging
one of the keyboards back into a USB port I would get a message saying it was installing drivers; and then would fail in installing any.
After a bit I navigate through the menus with just my mouse and do a system restore to before the GPU drivers were installed. After that, I started windows in SafeMode and then turned my computer off. Finally, I unplugged my computer completely
of all plugs (including my power plug), waited a few minutes, then plugged everything back in again. Amazingly, this fixed the problem, but then it got worse.
After about an hour of gaming, my computer BSOD's, most likely because I decided to alt+tab out of Tomb Raider during a loading screen to stop a video I had on. I restart my computer again, and then the problem returns, only this time absolutely
no USB devices work except my one keyboard. The backup keyboard, and both my regular mouse and backup mouse stop working a few minutes after logging in. I try to fix the problem like before, but to no avail. Any USB device I plug in either
gives me the "USB device not recognized" or attempts to install the drivers and then fails.
If there is ANY way to fix this problem, it would be greatly appreciated.

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.
