I have come across the same problem that apparently many Windows users are ailed with.
 
I thought I found the solution here when I googled the topic and was lead to this post http://www.ntcompatible.com/Desperately_need_help_---_USB_Devices_Not_Recognized_t32356.html
 
It seemed to work for everyone else, but it hasn't worked for me.
 
I have already done the Microsoft Standard 'moron checks' and I have added the stated USB Key to my registry. Nothing. I even unpluged my computer from the power supply twice, and still nothing.
 
My problem though, doesn't seem to be with any Modems, Printers, or flash cards..Instead my problem is with my USB Logitech Mouse and my APC Battery backup Power Strip.
 
My Device Manager tells me that everything is working fine. But when I plug in ANY USB Device, to ANY Port, it comes up as Unknown Device, and I get that annoying Malfunction Bubble that everyone else seems to get.
 
I don't know where else to go... I feel like Microsoft is just as much in the dark as the rest of us about this, and I was very excited to see that I'm not the only person with this problem. I almost got mad and formatted my computer, which I'm happy to say, I didn't go through with, because after finding this forum last night, I read that the format didn't work, and that would only add to my aggrevation.
 
Let me go ahead and follow suit by leaving you with some system specs.
 
Computer:
Alienware Area-51
Pentium4 3.1ghz
Windows XP Home Edition
Service Pack 2 (fully updated)
1gig DDR2 RAM
160gig HD.
ATI Radeon 9550 SE Video
Audigy 2 ZS Sound
ASUS PC4800 Mobo
 
If anyone has solved this problem or has ANY other methods I could try, please please let me know, I appreciate any and all help.
 
PS- I wasn't able to reply in the above said thread, thats why I'm making a new post out of it...sorry for inconvenience.
 
Thanks again.

OK, PEOPLE-------IT'S CONFIRMED.
If you have a Samsung MP3 Player, or possibly any other MP3 Samsung built music device (mine is the Juke Samsung phone)-
IT WILL CRASH YOUR USB. I have called Samsung and Verizon on this issue, and of course "deer in the headlights" when asked about this problem. So far I have tried the usual fixes,and the only one that seems to be working so far is disconnecting the PC from the power source for about 10min. Has to be completely off. We'll see if that will hold for now. And I will not be pluggin in the Juke ever again.

I'm pretty sure the problem doesn't come from a certain type of mp3 but just one of those that are cheeper. The reason I am saying this is because one of my friends bought an mp3 called missil and when I tird to install in on my computer my usb ports started to malfuntion(well 1/2) and the other one reads it for about 2 secondes and then malfuntions... I have no clue what to do. Also when I plug in my psp and try to put in music it starts downloading for a seconde and then the usb isn't recongnized anymore?
 
Any help?

Wow, this post started in Dec 2006 and now (Feb 2009) people (including me still have this problem!
 
I am using an HP pavillion DV4 laptop running windows Vista64. All of a sudden I was having the same USB problems everyone else here had. I cant say exactly which of these USB devices stopped working first:
 
Logitek wireless Laser mouse nano
SONY MP3 walkman
Garmin Forerunner 305 GPS
 
After these stopped working (they still get power from the USB ports but cant transfer information) my Scan Disk micro cruzer flash drive had the same problem.
 
I have tested my mouse and my flash drive on another computer and they work fine-i suspect the same will be true of all these usb devices.
 
I then tried a very old wired mouse and had no problems using it.
 
So far, I understand from my tests and from these posts:
 
its not vista, logitek, or hp specific (but logiktek usb devices may be more likely to lead to this problem?)
it seems to affect usb 2.0 not usb1
the usb2.0 devices show up as unknown devices in device manager but i dont get the yellow symbol with an exclamation point
 
 
 
There are several fixes posted and I haven't tried most of them. I'm going to try deleting the usb devices from the device manager and let windows reinstall them and if that doesnt work i'll try a system restore to last week (its been a problem for a few days only).
 
Did anyone else try a system restore? I didnt see that mentioned in any post (although i did see that reinstalling operating systems didn't help!)

when i removed all the usb stuff from the device manager and windows reinstalled the drivers, I got the same message before i even attached anything to my laptop!
 
upon closer inspection I realized that the built in webcam is a usb device but I dont think that is the problem.
 
When i double click on the conflict, I get the "USB device not recognized" window listing:
 
USB Root Hub (2 ports)
Unused Port
Unknown USB Device
 
...but there is nothing plugged into my 2nd USB port!
 
This makes me think its a hardware problem and something got fried inside my laptop
 
when i plug in a flash drive and my wireless mouse receiver, the listing above changes to :
 
USB Root Hub (2 ports)
Unknown Device
Unknown Device
 
sometimes one of the 'unknown device' is in bold, sometimes the other
 
any new thoughts on the problem?

Tarek: I have a repair job here that is having the same issue:
(v6000 laptop vista home premium 32bit)
 
I tried a virus scan
Bios to default settings
Uninstall USB & Re-install
 
I even did a erased everything and did a factory restore. NO LUCK!! If you find a resolution. Please post and if I find an answer I will do the same for you.

Ok, this is good but annoying. I turned on my laptop and it began installing usb drivers for the built in web cam at the top of my laptop screen. The drivers should have already been there because i erased them previously and then windows vista64 automatically installed them.
 
Since my laptop seemed to be rreinstalling USB drivers on its own, I tried plugging my Forerunner 305,my logitek wireless mouse, my Sony mp3 player, and my ScanDisk Cruzer-all are recognized. In short, my computer fixed itself after having this problem for about 8 days.
 
What does this mean? @#$@% if I know. My current guess is that there was (and still is) a loose connection in my computer that is causing USB errors. The only way it would install a driver when i booted up is if it suddenly recognized hardware that was invisible before hand. My webcam is built in-there's no way for me to physically remove it. Maybe something wasnt connected between my motherboard and the webcam (which is a USB device even though it doenst plug into a USB port)and it caused other USB detection failures.
 
To everyone else who has this problems-do you have any USB devices built into your computers thatare not attached through a physical cable? If so, you might want to try disabling, running diagnotics on, or talking to your computer help people about internal usb devices that could be malfunctioning.
 
I'm still interested to know what this problem actually is, (especially because it could just as quickly go wrong again)so i will keep reading posts here

I have got the same problem as you before.
 
The solution I have done is that I removed all the usb stuff from the device manager and then power off the computer. Once the computer is turned off, I also detached the power cord connected to the computer. If you are using a laptop, I suggest also remove the battery. After a short while, I attached the power cord to the computer again, then turn it on, and the problem is gone!
 
I hope this would help you to solve the problem.

Try this:
 

(disable that driver)
 
P.S. the name of that driver could be different on your system but the USB2 could be the same.

Hi,
Guess what? I have the same problem but has progress to more of a problem. It is my daughter's laptop (compaq V5101US). The problem started when she was downloading a movie to her ipod. She wasn't at the computer at the time but when she checked the status, the computer had shut down. When she tried to start up it gave her the fatal blue screen every time she tried to start the computer. I picked it up a couple days later and it booted up but neither of the usb ports would work. Same message you guys are getting. Like you I tried all the things that others have tried with no results. After several days of trying I was prepairing to call it a night after running an antivirus scan. The computer froze causing me to manually power off the computer. Now when I turn the computer on I get a few seconds of the fan and then a few seconds of DVD (optical) drive then nothing but a black screen. I am at a lost. I strongly believe the original problem has cause the current problem. A couple of techs say motherboard, but I am not convinced. What are your thoughts. Sorry for the book I just wrote.

Hello fellow frustrated friends,
 
I too had this problem and after many days of reading different ways to get my USB memory stick working enough to retrieve all of my important work files, purchasing software that "claimed" would help, I have found a simple solution that worked for me!
 
Hold down the "SHIFT" key while inserting the memory stick. You will get a prompt asking you if you want to turn on filters. Click yes and VOILA, you will hear the little ring of the hardware detected. After files are retrieved to a safe place, reboot the system.
 
I simply moved all files from the USB stick to my PC and then discarded the memory stick making sure everything was deleted. I do not know if the stick was repaired to function properly or not, it was not a chance I was willing to take for a second time.
 
Hope this helps.
 
Good Luck!

Add me to list of people having this stupid USB issue!!!
 
I have no idea why this started but here is the jist of it: About 2 weeks ago I started getting the pop-up "USB Device Not Recognized" and when I double clicked I get the following: One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. Below that is:
 
USB Root Hub (2 ports)
Unused port
Unknown USB Device (this is highlighted)
 
I kind of ignored it for awhile but when the pop up kept coming up about every 2 seconds it began to frustrate me.
 
I have double clicked the "malfunctioned" device and it is listed as port 0. I have checked the Device Manager but NONE of the USB devices display a red X or a yellow triangle. It is like I have a ghost USB device.
 
I have tried detaching the USB devices, uninstalling them and then rebooting and having Windows reinstall them, didn't work. Tried reassigning the ports, didn't work. This happens with both the USB mices I have and occassionally my USB wireless network card from Dell and they will stop working. The strange thing is I can start the computer and be fine for 3 hours and then it will happen. I have cleaned the USB connections and still nothing. I have the latest BIOS edition too.
 
I have attempted to see what would trigger it but have come up empty handed.
 
This is our main computer at work and I am at a loss. The computer's stats are:
 
Dell Dimension 9150
Intel Pentium D processor
Microsoft Windows XP Home with SP3
3 GB Ram
ATI Radeon HD 3400 Video Card
 
Between the Monitor and the CPU I have 11 USB ports and 4 right now are empty and I am still getting the pop up. All the devices seem to be functioning though. Anyone have any ideas?

Thanks alot, this worked for me, but the only problem is that all devices are now using USB 1.1, which vastly limits their speed, trying to transfer songs onto my iPod, christ it's taking ages. But at least I can now actually use my USB devices. So maybe if this also works for other people, your clever little minds could maybe come up with another fix to use USB 2.0!

Good luck guys

This is sad sad sad - I am having the same issues and as another poster said - it has been happening for years. I have a rather new Sony VAIO with 64 bit vista. My daughter plugged in an HP digital frame to charge it and I can no longer use any USB port - except of course for the HP frame : (
 
I need a mouse but I really do not want to reinstall to factory settings because I do a ton of software development and ... it would take weeks to get back to my current state.
 
I bought a mouse today that uses its own drivers thinking that may help but to no avail. I am going to try the suggestion to power down, unplug, remove battery and so forth. I will let you know how it goes.

OHHH YEAHHHH thanks to jingle for suggesting powering down and removing the battery. This is of course not a real fix but I am thrilled beyond belief to have my mouse back. THANK YOU TO THIS FORUM - this was a life saver!

I guess this problem is widespread and there's no clear solution for this whenever we go for questions. Even in Microsoft.com or any other gadget-troubleshooters guild we can't find any damn answers.
 
I have the same problem as with you guys. It started when I had installed my SAMSUNG D900 installation software. After using it for my cellphone then our video cam that we always used for me and my brother's favorite hobby: chatting in Friendster, just didn't function. We thought it was just a minor computer lapse but as weeks go by all 4 USB ports just reads: "USB DEVICE NOT RECOGNIZED". What the f***?
 
I tried to find solutions but I just couldn't find any. I doubt even Bill Gates can't solve this problem. Or if there's already a solution, would it be suitable to all computers out there?
 
What say ya people?

I guess this problem started when we installed softwares that uses USB ports? like mp3, cellphones, digicam, videocam.....
 
What do you think guys?

HI Guys dis is Erick Gipit from the Philippines
 
I hope my solution would be appropriate for all of you. But first let me tell you my problem.
 
My computer started to read "USB Device Not Recognized" after I had installed my SAMSUNG D900 Software which I used for downloading pictures, video,music from the Net to my D900 Cellphone. Unfortunately, my computer didn't recognized my 4 USB ports. And it was a real pain in the arse coz I wasn't able to use my videocam for chatting - which is my fav past time. So, I tried to find answers from forums on the net and found out about "compatdb.com"...
 
There was a tip where It told me to unistall other USB program in my Control Panel - Add/Remove Program. And then to uninstall all the USB devices in my Device Manager in Safe Mode. And turn off my computer and unplug all power cords. After few minutes I turned on my PC in windows and bhwala.... It worked again... Now I can use my favorite webcam for chatting.
 
What I learned is that maybe if we've installed a software for our cellphones, mp3, digicam, videocam in our PC it installs other USB ports and software. This probably blocked other USB ports and cause them not to read your USB Device/Hub. Just like what happened to me; Samsung installed other port in my Device Manager - Universal Serial Bus Controller. I forgot the exact name of that port that Samsung created. But after uninstalling it, my 4 USB ports started working again.
 
I hope this would help you guys in your problem.

cause the Polyfuse on the motherboard to open. The Polyfuse will recover
automatically, once it has had a chance to cool off. Which is why I'd suggest
checking the hub, to see if it is emitting +5V on the upstream port.) as read on another thread, I think this guy is onto something...what do you all think?

Check out the other stuff this guy said, I think he might be on to something. The reason I say this is because I'm running Vista 64bit and hadn't installed any new devices for a few weeks, hadn't altered any other device drivers in any way, nor had I downloaded any software updates from MS recently.

The issue seemed to happen only after I got a new pair of headphones. These headphones (non USB) have a significant amount of exposed metal, and a couple of times that I've been sitting in my chair in a rather dry room with very cottony sweats on, I have moved around rubbing a blanket or removing it from my lap. This caused a rather painful static discharge IN MY EAR as the static arced from my body to the headphones. The headphone jack for my computer is right next to the USB jack so I wonder if there could have been some electrical discharge into that...?

So if anyone is sharing their issue please try and remember if there had been any special electrical disturbance lately. I.E. solar flares, local DARPA experimentation, paranormal activity, or other related particle physics anomalies. No but really, anyone else notice problems after some sort of electrical disturbance?

Today I spent most of the morning and into the afternoon trying to get her USB ports to work (Xp pro Desktop). Uninstalled all USB ports, rebooted, No Luck. Reinstalled the mobo mfg provided Drivers. Fumbled around in the Registry, ran various registry tools, but still in Device Manager, I had one USB port with Unknown Device on it and a nagging windows popup saying that the USB stuff had a problem (Gee, I iddn't already know that, You Stupid @#$%#@$. The port would not delete or uninstall and caused the computer to "freeze" during shutdown.
After reading the posts in this forum, I unpluged the power cord let it sit for 30 minutes, and fired that puppy up. I'm proud to report she's purrin' away and momma bear now has moved on to other things to crab about. Thank Ya Lord, and you Good Folks!!
 
Good Luck
