USB ports no longer work after the downgrade to windows 7

I bought the new laptop model No.: E5 - 574G. It comes with windows 10 I don't feel comfortable with windows 10 then, I installed windows 7, but after installation of windows 7 and I installed all the drivers and even driver USB but USB is not showing / detection with laptop. I see when I go the usb is connected present in the BIOS boot sequence. I have also followed the process of uninstalling the driver and then restart the windows but it does not solve this problem.

Let me know how can I solve this problem.

Thank you

Pleasantries,

Mufasil.

  • Satellite Pro 6100: USB port does not work after the return of the mode "Eve"

    I have a strange error on my USB ports on Satttelite Pro 6100 with XP SP2.

    Two USB 1.1 ports work fine after cranking up what the laptop goes into mode 'sleep' (automatically or manually).
    The restart afret optical mouse connected to the USB port does not illuminate and the XP system displays the error message on the device not recognized on USB port.

    Plug the mouse on or off doesn't change anything. Only restart helps.

    Any ideas?

    It's very strange, but it will be interesting to see if the same problem persists with other USB devices. Can you test and post again on the results?

  • Satellite L855 - 14 p - USB ports do not work after the mode 'sleep'

    Heya guys,

    I have a strange problem today. The 2 USB inputs on the right side of the laptop (idk who is 2.0 or 3.0) does not work with the reason I can not perceive. These 2 guys are on different days, but in the same way. A month ago, I plugged the mouse USB wireless to one of them, then entered mode 'sleep'. When I came back, I discovered the work of mouse aint.

    Then I realized the port I plugged the key USB has no electiricity inside no more. I found it very strange and continuous without using the port of broken, until yesterday. Yesterday, I made the same mistake (a la mode "sleep" in a USB port plugged into the other port - work-) and I have re-opened, the 2nd port is broken in the same way, too. I've mastered Manager devices, regedit, but it has no use. This lead me to think his could be a hardware problem, but how can be possible? Is this a coincidence?

    Now, I have to use my 3rd and last port on the right side of the laptop with a USB duplicator.
    You have any ideas? Can it be a software problem?

    Understand this correctly? The USB ports mentioned don t work even after restarting a new laptop?

    In this case, it could be really a hardware problem
    But before talking about hardware problems, I recommend to recover the laptop using Toshiba recovery.

    Defining the notebook back to factory settings will help you identify the problem: If the USB ports wouldn't work, this s hardware problem.

  • USB ports no longer works after L7680 OfficeJet Pro printer installed...

    I am running Windows XP Pro SP3.  Before you load the printer all my ports worked (4 on the monitor, 2 on the front of the PC).  Once I'm installing all of them stop working.  The only option is to work with one on the front of the printer.   I am able to get my Western Digital HD to work on the USB port printer, but this one is fickle and only works sometimes (I have to restart to operate when it gives out).  I'm not able to use on the printer port USB flash drives. I f the usb port on the printer does not work, so I have no options.  I tried with a powered hub and it works at all.

    I was chatting with representatives of HP without result. If a HUB on the printer does not work it is a useless tool for me.  I need one that has no readers, etc.  Is this a reason to return to the item under warranty?  Or y at - it a way to get this thing to work.

    HP wants to tell me it's Dell.  Dell says it's HP.  I'm so confused and frustrated.

    What I discovered, after about 3 years, the computers are generally obsolete.  My computer was 1.1 ports and the printer connection 2.0.  As see you all new USB components say they are 2.0, but can work with 1.1.  Long story short, after reading this somewhere, I decided that I had to upgrade my ports.  I went to Microcenter (they have an online store as well) and bought a USB 2.0 PCI Card for $11.00.  At opened her top and broke in the new port and everything works well again.  It may not be what you want to hear, but it was all I could do.  I was told all empty printer resources USB and this is why the upgrade was necessary.  Hope this makes some sense to you.

  • Dell XPS 14z 3 USB port no longer work after reinstalling windows

    but the driver of the USB port of the SS was not installed. (you can see on the device as "Universal Serial Bus (USB) Controller" Manager without driver)

  • USB ports does not work after automatic update in Windows 8.

    Hello

    There was an automatic update that occurred a few nights ago on my computer that I never knew until after that I turned on my computer back the next day. The computer starts up, then stopped and restarted about twice more - a total of three reboots in all.
    It is really annoying, because my Bluetooth has also stopped working a few days before. So I'm completely paralyzed - I've been using USB keyboard and mouse since the Bluetooth went bankrupt. I can not connect.
    The computer starts as usual. The 'numlock' keyboard lights, like the optical light under the mouse; This happens just before the Windows loading screen. However once windows loading screen comes and the "pearls" downstairs begin circulating, the mouse and the keyboard go quiet. I am sure that there is no hardware problems, and the keyboard and mouse work on my Mac very well.
    I tried system restore and PC options refresh on the Startup Options page, but unfortunately, my hard drive is unlocked, and system restore won't work; It says that I need to specify which Windows Installation to restore. I also tried my options with the Windows CD.
    Do a complete restore of the system is not really something I want or feel that I can do. Being the sidenote, I have school work on this machine in question, and it was already over. Otherwise, I would have not had any problems.
    Anyone had this problem before?

    Hi, I just have this problem, but I have noticed that the driver has been disabled, when I activated, it works fine now.

  • Logitech USB mouse does not work after the upgrade to Windows 7

    I have a HP Pavilion DV6XXX laptop computer series (MS Vista Home Premium has been loaded from the factory), recently updated with Windows 7 Home Premium.  It is then this problem began.

    Wherever I am, everything I do (typing, surfing, reading) my cursor made a break of about 3 seconds, 26-28 seconds.  This interruption is making me crazy!  Everything what I'm typing, the cursor becomes unavailable for 3 seconds.  Everything I typed is gone.

    My laptop has a touchpad, but I use a Logitech USB mouse.  I can't disable my touchpad, but that does not change.  In addition, it is matter if I type or not: my cursor disappears for 3 seconds, 26-28 seconds.  I can sit and watch it.  I have disabled the touchpad, unplugged the USB mouse, find the updated HP drivers and Synaptics to nothing does not.

    Looking for other suggestions.

  • PayPal buttons no longer work after the upgrade to Windows 10

    I have recently upgraded to Windows 10, but have always set my default browser on Firefox 39.0. Since then, I discovered some really weird things happening.

    It is more disturbing with PayPal buttons. I kept a few Web sites and, even though I made no changes to the PayPal coding, the button does not appear on pages when I view it in Firefox. I can see them in Chrome or MS Edge very well.

    Here is a page of one of the sites in question. : http://projectsister.org/ : this is a site created in WordPress. On the right sidebar, it would take a "Donate" button However, when I view it in Firefox, I see the slogan of PayPal ("PayPal - the safer, easier way to pay online how!")

    Here is another example of a site that was created using Dreamweaver. : http://www.villagekitchenshoppe.com/take_a_break_class.html

    So, as you can see, both of these sites have the same problem and they are not even related.

    Does anyone have this seen yet? Is there a solution I don't know? Any suggestions would be very helpful.

    Thank you!

    Firefox can display the "Alt" text for an image if the image does not load. The alternative text for the Paypal buttons orange is indeed "PayPal - the safer, easier way to pay online how! But why not load these buttons.

    What happens if you try to access it directly? Right click > view Image, or you can try these links:

    https://www.paypalobjects.com/en_US/i/BTN/btn_donateCC_LG.gif

    https://www.paypalobjects.com/en_US/i/BTN/btn_buynow_LG.gif

    (Note: mine include the language code en_US, which probably varies from one country to the other.)

    Many users Windows 10 have been posted on the problems to access secure sites (HTTPS, addresses). If you get errors certificate, they are on most of the HTTPS sites or just a few?

    Many HTTPS sites problems can be caused by Firefox is not completely set up to work with your security software. Are you not using Avast, ESET, Kaspersky, BitDefender or another program that intercepts your navigation for filtering?

    Problems on a smaller number of sites could be caused by other factors, individual on the site or resulting from content filtering (for example, parental controls).

  • Satellite Pro L20 USB ports no longer work

    Hello

    A little bit ago, I experienced a few problems with my Satellite Pro L20. After he brought to life, I found out that the USB ports no longer work.

    Things I've tried so far:

    Reinstall the chipset drivers
    Update the BIOS.
    Ensure USB is enabled in BIOS
    Uninstall and reinstall the USB controllers via the Device Manager.

    The USB ports no longer work and I ran out of things to try. Any suggestions?

    Thank you

    Hello

    If possible, try to install the operating system with recovery media. On this way, you will have to factory settings. It's the best test you can do. If the problem persists, it may be a malfunction of the equipment. Sorry but on this path is not easy to tell what the problem may be.
