Window vista xps 420 problem with USB ports.

I have problems with window vista dell xps 420 machine, all USB ports are not recognized, unless the computer is restarted or rebooted. anyone has a suggestion.

Hi Miguelsmith,

1. When did you start to question?

2. you remember to make changes to the computer recently?

You can uninstall and reinstall all USB device manager entries and check if it helps.

a. Click Start and typedevmgmt.msc and then click OK. Device Manager opens.

b. expand Bus USB controllers.

Note: You will need to scroll down to find this point.

c. the first USB controller under Bus USB controllers right click and then click on uninstall to remove it.

d. Repeat steps above for each controller USB is listed under Bus USB controllers.

e. restart the computer. After the computer starts, Windows will automatically check for changes on the hardware and reinstall all USB controllers that you uninstalled.

f. check the USB device to see if it works

  • Problem with USB port and touchpad satellite A135-S2386

    Welcome!

    Laptop Satellite A135 in Houston, I bought about a year ago, it was working fine until last Friday. All my USB ports stoped working.

The same situation is under Linux (ETCH Deiban), the USB ports does not.

    Hello

    If the problem persists after using the original recovery media is certainly hardware related issue. I recommend you contact the nearest authorized service provider. They check your laptop.
    Sorry, but I really don't think you can do it alone to solve this problem.

  • Just bought Wndows Vista and having problems with the port for Palm 125

    I just bought a Windows Vista-based computer and have problems with getting my 125 Palm to synchronize with the desktop computer.  I get an error message saying: "No available Com1" what should I do?

    Thank you

    Frustrated

    Don't ask me the procedures step by step that I did, but I finally success!  I uninstalled Palm Desktop and started from scratch.  I unplugged the Hot Sync cradle by the USB port, then I installed Palm Desktop from my drive and then update Palm Desktop on the Palm for Palm M125 site.  It still does not, I manually added a port and manually changed to COM1.  I then pressed the Hot Sync button and in the Device Manager, a folder has become available "device named" with Palm Desktop as a subfolder.  It is always active, I updated my computer for Palm USB driver.  Miraculously it worked.  Thanks for your help, but as usual everything it needed, it was patience and trial and error to solve the problem, since it does not seem to be a quick fix related this topic.

  • Satellite C650 problem with USB ports

    Hello

    I have a problem with my laptop, with my USB ports.

    A few days ago, I plugged my mp3 to charge its battery. I did when system Windows began and after a few ports seconds has stopped working. They work for one to five minutes after starting my computer, but only after my laptop's turn off for a few hours at night for example.

    They work fine and all of a sudden we hear the sound of a disconnected device and usb ports turns off. I tried many solutions but nothing worked. I removed all the USB ports in Device Manager.

    I checked in the BIOS, but everything seems to be okay. I tried to disable the disconnection of usb ports to save energy, nothing. Tools that have been provided by Toshiba to check hardware see as usb ports work correctly. Only usbdview program sees as unknown device, I tried to uninstall it through this program but still nothing.

    You have an idea, what could happen? Or if there is no possibility to fix without service visit?
    I would appreciate your help.

    Hello

    Have you tested these ports USB plug a USB mouse or a USB keyboard?
    These devices work properly?

    I don t think you need a visit to the service.
    I think that it s just a software problem
    Given that the USB ports are controlled by the chipset, I would recommend reinstalling/updating the chipset driver

    The alternative is a bit drastic, I think about the recovery of the laptop...
    It might be possible that the registry has been confused upward or some 3rd party software preinstalled on the laptop could affect the USB ports.

    I remember that my USB ports do not work after installing iTunes.
    I had to reinstall the operating system once more to get the USB port work even more funny is that I installed iTunes once more and USB worked correctly

    I use Windows Vista Home Basic on a Dell Inspiron 1501.  I have recently accepted that some guest downloads Windows with terrible results.  First downloads do not appear to have been accepted and the system of guard stop and startup trying to cancel.  Second as I result, I seem to have lost access to a range of Windows tools.  For example in Panel I can't open system icons or Windows Update.  Nor can I access these services from any other avenue on the computer.  Whenever I have find an icon or a file screen flashes a dialog briefly and then disappears.  The effect of this is that I'm completely unable to access or to implement the recommended tools or services that could solve this problem.  My ability to manage my computer has been reduced to zero.  Dell were not receptive and I can't get a response from Microsoft

  • Problem of USB ports: remove the material does not work. It works on different computers for the same USB devices

    Original title: problem of USB ports:

    I have a computer dell laptop inspiron d1420 provided with Windows vista and I have upgraded to Windows 7 ultimate, I noticed that when I plug in a USB mass storage, when I try to remove it, I don't get the safe delete the message and lately when I try to remove it, I keep getting the message He's busy and I can't remove it. I tried the same USB on another PC and I have no problem at all. I connected a printer, USB cable and wondows llok have not the driver or didn't install the printer, he left as a device not specified with the name of the printer, but I can't print. I tried with another PC that is also running Windows 7 ultimate and I have no problem, windows has installed the driver, because I used the same printer and the same cable. What is the problem with my USB 4 ports and how to fix?

    Hello

    When you get this message while trying to remove a USB, it's basically a lock for this USB device by some process running on the computer. If we know which process is this locking mechanism, we could also find which Service is associated with this problem in the computer.

    To check this, you can use a program called Process Explorer. You can download this program from the following link. Once downloaded, extract the contents of the zip downloaded to a folder on your desktop. Inside this folder, you will see a file by the name of procexp , which is the executable for Process Explorer. The download link is:

    http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653

    First, plug the USB to one of the USB ports. Then, once you have the executable to Process Explorer, right-click on it and then click run as administrator. Please allow all guests UAC can occur. Once the Process Explorer is running, please follow these steps to search for processes using the USB at the moment:

    1. click on Searchand then click on manage to find them or DLL on the options menu at the top.

    2. then in the pop - up which will turn up next, type the drive letter for the USB drive connected to the computer (for example G: or H:) right now and click on Search.

    3. he should then display all instances of the process that is using this USB at the moment with the corresponding process ID (PID).

    Now, once you have the names of processes using the USB at this time, you can terminate them by clicking on them and then clicking on Manage close. Once this is done, you should be able to eject the USB safely.

    I would like to ask the names of processes lock the drive in your computer. This should give us an idea of what we might have to take the next.

    In addition, for the other issue that you mentioned, in which the computer does not automatically and correctly detects the printer when it is connected to the computer, I suggest you to check whether or not your computer Plug-and-Play service is set to automatic. Here's how you can do this:

    1. press the Windows and the R on your keyboard to get to the top of the run box.

    2. type Services.msc in the run box and press enter on the keyboard. Allow all UAC prompts that may coming up next.

    3. once it opens the window of the Services for you, scroll down to the Plug-and-Play service and double-click it.

    4. in the properties box that will come next, the Startup type should be set to Auto and the Status of the Service must be started. If this isn't the case, please put these values.

    5. click on apply then OK, close all windows in the computer and restart the computer once.

    Once these steps was performed, please check if the problem remains the same. We know the results.

    I hope that these steps raises you in the right direction in order to solve this problem. Don't answer if you still need assistance, we will be happy to be of assistance.

  • Problems with USB drivers

    My USB drivers dies randomly, and I followed the instructions to remove them all and restart. However, after the restart, drivers are unable to reinstall. That's all, after my webcam does not work and I followed the instructions here http://answers.microsoft.com/en-us/windows/forum/windows_vista-hardware/windows-vista-error-code-28-with-webcam/9070b7f6-d5b5-413b-acf9-d5cba24580c9. After that, all my USB drivers no longer completely be frustrated I dropped for the moment.

    So here's the problem when I start my computer, it tries to install all drivers and every one of them goes down. However, things that I plugged the USB drives actually work until it tries to install the driver fails. I tried to disable the automatic driver download when booting with the computer and management through the system option to never ask me, but he always does! It's like a nightmare! Is there a way to disable these pilot automatic downloads other than the two options, I tried getting started? Or better yet, is there a way to fix this, other than to reinstall windows, which is not a really fair option.
    I tried EVERYTHING, manually install the drivers automatically, delete them and restart and so on. Thanks for your help
