  Possible hardware USB badly shot - if a PC you can disable the onboard USB and use a
  3rd party card extension that are not expensive. If a laptop then you will need technical assistance
  a real computer store (not the leeks and the glances at a big box BestBuy or othe stores) or system
  Support from the manufacturer.

  Also check with the manufacturer of system and their forums support (as appropriate) for known problems and/or
  solutions.

• My USB ports don't work. I followed steps everythings is recommended for microsoft and nothing

  installation of USB, updated

  Hello

  ·        What are the steps that you took to resolve the problem?

  ·        Since when are you facing this problem?

  ·        Remember to make changes to the system?

  ·        What happens when you try to plug in external devices on the system? You get the error message?

  It could be that the USB drivers have not corrupted. I suggest you to uninstall the drivers from Device Manager and let windows when the system boots reinstall it. Follow the steps mentioned below.

  a. click on Start menu and type device manager in the search box of start and press ENTER.

  b. click on the USB (Controller Universal serial bus) to develop the list and remove the drivers that are installed on the system.

  c. close Device Manager, and then restart the computer.

  d. let windows install the drivers for the USB ports automatically.

  e. Once you have reinstalled the drivers, connect the camera and check if you're able to connect to the system or not.

• HP Envy m6 1125dx: USB Ports are not working please help

  Hey all,.

  I had problems with my USB ports on my laptop Hp Envy M6 1125 DX. Only 1 usb port works and the rest do not work. I tried everything to update the BIOS updated the drivers from the site. I don't know if the driver is not installed or if it's just a bad USB port, but I didn't really notice it until recently, when I bought a headset and I couldn't use it as my only working port is used by my mouse.

  In the USB tab in Device Manager, it has the following features;

  Generic USB hub

  Generic USB hub

  Family of chipsets Intel (r) 7 series/C216 USB Enhanced Host Controller - 1E2D

  Family of chipsets Intel (r) 7 series/C216 USB Enhanced Host Controller - 1E26

  Composite USB device

  Composite USB device

  USB root hub

  USB root hub

  None of them have a yellow exclamation point so my best guess would be that is missing the drivers for the rest of the ports, but I have no idea. I'm in for this reason excrutiating pain, I'd appreciate any help.

  Thanks in advance!

• Re: USB Ports do not work on my Satellite L830-145

  Hello
  I have Toshiba Satellite L830-145 with Windows 8 and all USB ports do not work. Have updated the Intel BIOS drivers and uninstalled and so on tried a lot and still no luck
  Maybe here someone will have an idea

  When I start the computer power light before windows starts and goes dead when windows starts loading
  On USB3 I can recharge the phone, but it won t recognize anything in windows
  Any help much appreciated.

  According to specification for laptop, your laptop comes with Win8 64bits.
  Using the original version of Windows preinstalled?

  All that you have done is just, but if nothing is done, maybe you should try to reinstall original recovery feature by image and test with the factory settings.

  This boot problem after a storm in my area some time ago.

  Please can someone help.
  Thank you
  Sani

  Hello

  > This problem start after a storm in my area some time ago.

  Because other devices don't work properly and because procedure didn t get it back help you solve this problem, I think that the problem is related to the hardware malfunction possibly that the motherboard was hit by lightning, which would explain the problems

  I think you should ask the maintainer authorized Toshiba in your country to check the motherboard.

  But in my opinion, that the warranty does not cover the issues of environmental impact maybe your household insurance could help you

• 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.

• X 51 - R2. Before USB ports do not work

  I just got my new Alienware X 51 R2 recently. I begin to test on my new computer. Then I found at the front, two USB ports do not work! My USB device is functional because it works when I connect it to the rear USB ports. I don't know what problem is it? I tried to update and install the driver too much on Dell.com. It's a new pc and therefore disadvantage if the front USB ports do not work. Help, please

  Just for someone else who has this problem. It's actually all because the cable that connects the USB card to the front of the motherbard is connected with a black cable. You will probably find that opening upwards, you will find that the thick black cable is not connected.

  Once reconnected, you will have your USB market back again. You will also find that your AlienFX works. I just had this problem and after the challenging my brain trying different drivers, reinstalling the operating system, make drains of power without meaning, try all USB, I, I thought I would check the actual cable and voila. Hope it helps others in the future.
