USB devices not always working

Some USB devices do not work correctly when using the USB2
brackets connected to pins JUSB1 & JUSB3 pins on my k7t266 Pro 2/RU Board.
They always work fine on either of the 2 usb ports located next to the mouse & keyboard. I fear that the "USB controllers" may be incorrect.
How should they be named (and how many times) in the device manager ?

Hi,
Are you using the latest updates and patches?
Are you using WinXP with SP1?

  • Ipod "usb device not recognised" on one computer but works with another!

    I have a 60GB ipod video and a 2GB ipod nano. Both connect fine to itunes on my work laptop but will not connect to my home laptop. They have previously worked fine with the home laptop but now when conected the message "usb device not recognised one of the usb devices connected to the computrt has malfunctioned". I have tried reinstalling itunes several times and tried the usual reset of the ipods etc but nothing seems to work.

    If you have more then one USB port, try the other port.

  • AE 2220 - USB Devices Not Working

    My AE 2220 will not properly mount and access USB devices in any of the USB ports.  I've unsuccessfully tried to use three different thumb drives and a Sony camcorder and experimented with every available USB port.  The AE 2220 is running the factory default Windows 7 installation.  AFAIK, USB devices never properly worked.  Not sure what to do from here.
    Here are some symptoms I see after plugging in USB devices:
    Status bar appears as the device is being read/recognized and the status bar freezes.  Other times the status bar moves quickly at first, then slows to a crawl.  Sometimes the bar gets to the end and starts over in an endless loop.
    Sometimes a message box appears stating that the USB device is damaged (which it is not) and asks if I want to repair the device.  Clicking "Yes" does not fix anything.
    On some occasions the device mounts, but when I try to copy files to the desktop the copy freezes and hangs and I have to unplug the device and quit the process.
    Can someone please help.

    Hi,
    In addition to some group policy issue as Balaji Kundalam suggested, there should also be some permission problems.
    We could run gpresult /r to check which policy that might have effect on this issue.
    And for the permissions, we may take a look at the following thread:
    External Hard Drive "is not accessible. Access is denied."

  • Iphone 4S will not charge, error that USB device not working, found any suggestions?

    iphone 4S will not charge, error that USB device not working, found any suggestions?

    Hello Chambless,
    The troubleshooting steps below can help get your iPhone to charge.
    If your battery doesn't charge, or if your device shows a low-battery image, black screen, or "accessory not supported" alert, follow these steps.
    Inspect the connector at the bottom of the phone:
    Make sure that there are no bent pins in the connector.
    Make sure that the connector is free from debris.
    If there are bent pins or debris, please contact Apple Support.
    Otherwise, continue troubleshooting.
    Make sure that the outlet you're using works.
    Make sure that the Apple USB cable and Apple USB power adapter work.
    Plug the device in to power and let it charge for up to 30 minutes. If you don't have an Apple USB power adapter, try connecting to a computer's high-power USB 2.0 port (not a keyboard). The computer must be on.
    If the device still exhibits an issue, try turning your device off and then on again while connected to power.
    If the issue is persists, please contact Apple Support.

  • Itouch - USB device not recognized and Itouch now no longer works

    I'm now on my 3rd Itouch since December all due to the same problem. All seemed to be going well with my 3rd replacement Itouch. Having loaded most of my cd collection into ITunes the night before I was going on holiday I synced my Itouch. Some sort of automatic download took place I think from Microsoft and suggested my drivers were being updated. Next thing I got message to restore my Itouch to factory settings. I did this and all the problems I had with my previou Itouch's started again.
    When I now plug my Itouch into my laptop it says "USB device not recognized" and the Itouch will not switch on. I've done everything including reinstalling Itunes, holding down the power and home key but to no avail. Looks like I'm going to have to send my Itouch back again. I have a suspicion that a Microsoft download is corrupting the drivers. If anyone can help I would be very grateful. I really like my Itouch but the fact it keeps failing leads me to wonder if I should opt for something else.

    I had success with the holding down the keys and connecting to usb and using itunes to restore firmware like they show here

  • "USB Device Not Recognized. One of the USB devices has malfunctioned..."

    I'm running Windows XP with external hard drive. When hard drive is connected, iPod will not sync and I get message stating "USB Device Not Recognized. One of the USB devices has malfunctioned..."
    When disconnect the external drive, he iPod appears in My Computer. However, iTunes is on external drive; therefore music is not syncing onto iPod. I've attempted the 5 R's as well as searching for iPod in Device Mananger. When iPod is conncected, it is listed in Devce Manage as "Unknown Device."
    I've changed drive letters on boh iPod and external drive and get the same message. Please help.

    QRe: Zen MX Causes "USB Hardware has Malfunctioned" Msg from Windows XpyUhh, Yes.
    I used to same cable to attach my Motorola Razr and the computer correctly found it and identified it as such.
    I also tried another cable (brand new) same thing.
    I went to recovery mode and did a "CLEAN UP" but no dice.
    I also got my I.S. tech guy to look into it and on the USB page it say "UNKNOWN DEVICE"? when he tried to delete it it did not help, it just reappears as "UDVC"? Also in looking into it it seems to have no drivers.
    He came to this site and tried to do somethinm through here but it did'nt work.
    Now in listening to it last night it began to 'skip' or what I call 'HICCUP" terribly. Where a song starts and stops, during the middle of it. ? It's always done it a little but it has been getting more and more common and now? It's WAY worse about it.
    It has never been dropped, or nishandled in any way. I bought the clear hard case to protect it. And only has about 300 songs on it. Never used for anything else. No vids no pics, nothing.

  • Zen Extra "USB Device Not Recognized" ??? HEL

    Hi all,
    I had a MPIO 20 gb MP3 player wich was stolen. No biggy, I took advantage of it and upgraded to a Nomad Jukebox Zen Extra 30gb. It look and feel nice and the navigation seems really easy. Where it gets more difficult is the "simple" pluging in!!! No matter wich USB port I use on my PC, I always get the "USB Device Not Recognized" message. Front port, motherboard port nor soundcard port (Audigy2) dont work.
    Any advice, I really need help here!
    Thx for your time,
    Jacq

    I just bought a Zen Micro and had the same problem, the issue is with the USB cable. I had an extra cable from my digital camera and using it, the Zen Micro was recognized immediately. I've seen the issue posted here by other people too. You could try to return the player and chance getting another one with the same problem. If I didn't have a spare one, I would have just picked up a new one up at Radio Shack or Best Buy...

  • Re: "USB device not recognized​." "The connection between your device and the desktop could not be establishe​d. Please check your setup and try again." Tungsten E2

    Have had my Tungsten E2 for 3 years...I always use cable to Hotsync, and the last few weeks it has worked only intermittently. Either the device is not recognized, or it starts the HotSync and then freezes.  I have checked out various online suggestions but then discovered that the only thing that seems to  work is to exit Hot Sync Manager, then restart it again each time - then Hot Sync seems to work fine - a temporary solution! I don't have Bluetooth capabilities.  I can't figure out if I need a new cable, a new OS (have Vista), a new laptop (only 2 years old) or a new Palm!  Any suggestions? Thanks!

  • B500 USB Device not recognized error at startup + sound issue Dissapointed

    Hello,
    We have 2 B500,
    whenever i start them, after windows load they are giving me an error, "USB device not recognized" I am not sure what to do any help will be greatly appreciated as this is strange that both the machines are giving the same error,
    also on one of the machines the sound does not come work, i have tried to trouble shoot, the diagnosis says speakers are working fine, but sound does not come out at all.
    I am kind of dissapointed with these issues, we always use to buy from Dell but we thought we would give Lenovo a chance, the machines were barely a couple of months old when the issue started,
    any advice please?
    Solved!
    Go to Solution.

    Well being that it is the same PC as the other I am sure the speakers are plugged into the correct spot. Have you checked the speakers with other devices to make sure the speaker is fine? Since the other PC's drivers are working, you can use DRIVERMAX to pull the sound driver from the good PC and also use DRIVERMAX to install the driver you pulled from the good one. Just uninstall the sound drivers from the bad PC first before installing the new driver.

  • Ipod not recognised by Windows, USB device not recognised

    Hi hope someone can help
    I have recently received my ipod back from Applecare who have sent the ipod back in ' working order ' but it will no longer be recognised by my windows. It says USB device not recognised and i cant find, nor will it install drivers that i located on the ipod updater etc.
    I have tried several methods on this forum but none seem to work.
    The letter from mycare says the iPod is formatted for a computer operating Mac OS X. Although i stated wi use Windows. But the leter states this can be changed bu installing the updater, but this wont make a diff as comp still wont regonise the device after i have followed there instructions. Any advice?
    Thanks

    I'm not really up on the complexities of the Windows OS but try this tip I picked up a while back, hopefully it might help.

    5. Scroll down the list of devices to the Universal Serial Bus controllers
    6. Click the plus icon next to the Universal Serial Bus controllers.
    7. Double-click one of the indented USB Root Hub entries.
    8. Click the Power Management tab.
    9. Deselect the "Allow the computer to turn off this device to save power" option.
    10. Click the OK button at the bottom of the window.

  • USB Device Not Recognized

    Operating system:  Windows Vista
    Error:  USB Device not recognized
    While actively on the computer, we suddenly got a message stating that the USB Device was not recognized.  The only thing plugged in to the USB port was a mouse.  Tried all the ports, same message.  Tried another mouse, same thing.  Tried a thumb drive, and low and behold, 2 of the 3 USB ports worked.  Tried a URL from MS which is supposed to help with this exact problem and possibly fix it:  http://windows.microsoft.com/en-us/windows-vista/Tips-for-solving-problems-with-USB-devices 
    This didn't work.
    Contacted HP support and they wanted me to restore back to a restore point as well as updating my BIOS.  After searching the issue more extensively using Google, I found that several people said to do this:
    Shut down the computer
    Remove the power plug
    Remove the battery
    Put the battery back in
    Power up the computer (without the power plug)
    This forces a hard reset.
    Almost as if by magic, the problem disappeared.  A much simpler and less technical solution to the problem than what HP recommended!!!!
