My computer won't recognize any USB devices pluggest into it, except my HP UBS Mouse. My iPod won't charge, my digital camera won't upload pictures unless the memory card is inserted directly, and even pen drives won't read. I'm confused as to why the mouse is working, could it be the sorce of the problem?

Hi,

I have a relatively new hp desktop computer and i have never had any problems with the usb ports and have used a 32mb lexar media jump drive for a few months. recently i bought a 4gb sandisk usb drive and the computer wont recognise it fully. it will make the beep sound when it is plugged in just the same as the lexar media drive, but i cant seem to find it anywhere else. it is not in any of the drives(I,J,H,etc...). please, is there somewhere i am forgetting to look?

HI TO ALL THOSE HAVING USB PROBLEMS WHERE UR COMP NO LONGER RECOGNISES THE DEVICES BEING ATTECHED TO IT..BE IT THAT EXTERNAL HARD DRIVE, PRINTER, CAMERA, IPOD ETC THAT WORKED BEFORE BUT NOW WILL NOT. IF YOU ARE HAVING THAT PROBLEM I MIGHT JUST HAVE A SOLUTION FOR YOU...DO NOT DO ALL THAT MAMBO JAMBO DESCRIBED ABOVE OR EVEN FORMAT YOUR COMP YET...THE SOLUTION AS I HAVE UNCOVERED IS TO UNPLUG YOUR COMPUTER FROM THE MAIIN SOURCE OF POWER (BE CAREFUL FOR PEOPLE WITH SHARED LINES...BETTER FOR LAPTOP PPLE) AND ALSO IF ON LAPTOP REMOVE THE BATTERY AND LEAVE COMP FOR ATLEAST 30MIN TO 1HR....RECONNECT AGAIN AND BOOT AS NORMAL (CAN CONNECT UR USB DEVICES BEFORE BOOTING OR EVEN AFTER BOOTING UP)..I THINK ALL WILL BE FINE...IF IT DOES NOT WORK MAIL ME CHEERS GUYS AND GOOD LUCK..SOME OF THIS THINGS WE SOLVE OURSELVES

I have read the article on the top of the page.
Leo, I have the same problem as the ""Suben" Dated February 29,2008" A recap of his problem is below. I have completely updated Windows XP Pro. I have updated and use all the spyware and virus software. I have delete my USB from the Device Manager then restarted my computer and I still get the ballon stating my USB is not recognized. My Mouse is USB and my printer is USB and both work just fine. Have not had a problem with them at all. But, when I plug in my USB HUB, flash drive, or IPOD it will not recognize any of them. I have plugged all three devices into another computer and they work fine. Can you help!!

Our computer has never given us any problems with our USB Hub but one day it did. It couldn't recognise any Flashdrives and indentified them as Unknown. I thought it was a virus but I have done a vrus scan throughout the whole computer with Trend Micro. The message from the computer says there has been a Malfunction with the USB. I can't remember the full message. it was in a yellow balloon. I run Windows XP Home. I used Norton Ghost to upload a previous ghost image and yet the problem is still there. This prooves it isn't a virus. The computer is about 2 years old and the USB Hubs shouldn't malfunction or shouldn't stop working.

"This prooves it isn't a virus." - no it does not. You can't
prove a negative. There is no way to PROVE that you have no
virus.

That being said, it sure sounds like the hub has failed.
Have you tried plugging devices directly into the computer
instead? Replacing the hub?

my miniSD that is inserted into a usb device is not working. it had worked before but the system froze when i was browsing the usb and upon reboot didnt read it anymore. sometimes it will show the drive in the "my computer" folder but i cannot click on it. tried to format it through DOS but still doesnt see it. it may be a problem with the miniSD as my phone freezes when i insert it there. only have basic access to this workstation as it is a shared computer in college. no administrator options

I am so frustrated. I have read every article on USB problems and called Western Digital and still my problem is not fixed. I tried uninstall all the USB entries on device manager. When I try to do so, my computer gets stuck and I have to force a shut down. When I plug in my WD Passport external hard drive, Windows XP does not recognize it. when i click on the device on device manager, it is called "unknown device" and under the device status it says "no drivers are installed for this device. This external hard drive worked perfectly when i first bought it a couple months ago. I saved all my files from one computer and then opened up the drive on another computer and everything was properly saved and everything was fine. Now--- I cant open anything anymore. Help please... should I just call it a day and assume that all my files are lost?

That depends entirely on exactly what computer you have and how things are set

options.

I have 3 USB 2.0 ports on my system, I don't know what happened but now they are all being read as USB 1.0 (i get the message that says that my device could run faster if i used USB 2.0). I have automatic update turned on so my windows should be up to date. My USB drivers may be old though...also when i went to check the driver version in device manager it shows 4 USB universal host controllers ("Intel(R) 82801FB/FBM USBUniversal Host Controller-2658/2659/265A/265B") and 4 usb root hubs ("USB Root Hub")...the appearance of 4 of each confused me...any help with this or a place where i can download new drivers would be helpful

When a usb device is plugged in, and doesn't come up with a drive letter, you have to go to ctrl panel, system,hardware, device manageruniversal serial bus controllers, and uninstall usb mass storage devices (start at the bottom). The pocket fob will then be recognized again, and come up with a drive letter. If it doesn't, uninstall the next one.

the flash memory in it may have been erased due to the impact shock. You should find that device's manufacturer on the net in case you can download some firmware for it - also see if there's some "hard reset" process for it

hello, After I plug in my USB, the search option comes up to search that USB. I have gone through the folder options and changed the different media to open up in a new window, but still no luck.

I recently purchased what is supposedly an Apple MPG player from a friend. The player already has files on it (MPGs) that will play when earphones are attached.
However, the player is completely filled, but I can not access the files to remove any of them. When plugged into my USB port, the unit charges fine, but the computer does not recognize the player. The port works fine (the player doesn't show on any of my friend's computers either. When I checked the paperwork, I found that: "This difital player is not a mass storage device, your PC will not make a data connection with the player. The USB plug is only intended for external power to conserve the battery"
Is there some way to reach these files & delete them? I guess what I'm asking is, "Can this player be turned into a 'mass storage device'?

Windows XP - my usb devices used to work, but now, it only detects my digital camera. I know they're not faulty since they work in other computers. No internet connection so probably not virus problem

I am unable to access the data in any USB mass storage devices through any USB port. The computer sees the device but I get the message "the mass sorage device is not formatted, do you want format it now? appears, even though the device IS formatted and works fine on other XP computers. Do you have any suggestions? Thank-you for your attention to this matter.

I have Windows XP Media SP2 and I have an external hard drive (Beyond Micro, not sure of the model) and I plugged it in, it worked fine and I was using it as i saw fit. Yesterday, for reasons I am unsure of, it suddenly stopped working. At the time it failed, I had a download going to it, which I do often, but it suddenly said access was denied and I assumed it meant I was not allowed to use the site, which I found strange. I later noticed I couldn't access the drive. My computer still makes a noise when I turn it on or plug it in and I can see it in the Device Manager, but it doesn't let me access the data on it, almost as if it doesn't exist. I uninstalled it and reinstalled it, but that didn't do me any good. I am now leaving it off and unplugged for a while to see if that helps, but in the mean time, do you have any idea what would prompt it to suddenly give up? Everything is completely up to date, but the device was working before so I don't believe that's part of the issue. Thanks a lot.

Hi I was reading an post that said:

>>>My husband's gateway laptop has three USB ports on the side which are all spotty in recognizing the device attached. For attachments (e.g., wireless mouse) that light when activated, the light being on is spotty in the same way. Is this probably a hardware issue?

Same problem here with my Gateway 3520GZ laptop I believe is an Hardware issue but I'm not sure.

In my case one port don't work at all, the other works fine and the last only work as USB 1.1 port.

Please can sombody help us to fix or realize what's going on here??

Sincerely:
Joe Berumen

My USB wireless adapter was working fine. Then all of a sudden it would not work and my it would not recognize my mp3 player either. But all other USB devices (like printer, ext hard drive, web cam) are working fine. I bought another USB wireless adapter and it is not being recognized even after installing the drivers. Any help would be appreciated. I am running windows XP pro. I did try switching off for a while and still does not work. Any help would be appreciated. Thanks.

For some reason, a new USB keyboard I bought to connect to my laptop doesn;t work. My laptop isn't recognising the new hardware and installing it. I think it is the USB ports because my mouse only works in one and so far, only my PDA, camera and removeable device work in the other USB port (the one not recognising my keyboard) what is wrong?

After downloading itunes update my computer will now no longer recognize any usb devices. Have tried system restore and uninstalling itunes, but to no avail. Have followed the prompts through "help", tells me the device is working properly and that no driver is installed, but when I try to load a driver it can not be completed and then that a driver is not needed!!
Went to system configuration utility in help and "Plug and Play" is ticked and "running", but "Universal Plug and Play" is "stopped", tried to turn it on, but it won't be turned on. Getting very nervous now, cos I'm at the limit of my understanding and knowledge. We are using Windows XP home edition.

My husband's gateway laptop has three USB ports on the side which are all spotty in recognizing the device attached. For attachments (e.g., wireless mouse) that light when activated, the light being on is spotty in the same way. Is this probably a hardware issue?

P.S. The CD/DVD burner (on the same side) also seems to be having problems reading and burning CDs...

Thanks for your time. Just trying to figure out what the problem might be and ran across your site. Consider yourself bookmarked ;)

Follow-up: I plugged a 4-port USB hub into my computer and then attached my MP3 player to it, and now it is recognized by my computer and works. I do get messages that it would work *better* by attaching to a high-speed port but, of course, none of those would work. I have no idea why this has tricked my computer into recognizing the MP3 player, but I'm willing to live with this solution until I learn how to solve the original problem.

I had no idea USB devices create such distress! I tried reading all the related comments but my problem seems slightly different. My SanDisk M250 MP3 player works on my business laptop (so I know the unit is operational) but not my home desktop. However, all other USB devices work perfectly on the desktop: keyboard, mouse, webcam, printer, removable drives, etc. When I plug in the MP3 player, a get a dialog bubble that the system has recognized a new device, but it doesn't show up in My Computer, Device Manager, Disk Manager, and the Remove device safely icon disappears almost immediately. How can so many other USB devices (some quite old) work but not this modern, new device? I contacted SanDisk tech support but they were baffled. They do not make a specific driver for that product.

Any advice? Thanks!

2006-08-27T20:32:53Z

Leo,
A question and a comment ...
Is there a limit to how many USB ports my desktop computer can have? I have four USB 1.1 ports and I see that there are internal cards I can install that offer 4 or 5 USB 2.0 ports.

My comment: Manufacturers aren't always telling us when USB 2.0 ports are necessary. Also, they don't make it clear when port expanders are lousy. My Dell Axim was barely functional on a USB port connected to my monitor, or when my USB backup drive is attached. Likewise for my Iomega Floppy Plus.
