• Tecra S2: HDD as unknown device on two of the three USB ports

  Hey again,
  I thought then that I was here anyway I could ask this too.
  The tecra S2 has 3 USB ports, they all work very well for my USB mouse and other small things like the wacom tablet...
  But when I plug my external hard drive in two of them, it says that it is an unknown device...

  I think, but am not sure, that this might have something to do with something once, we had to do in school;
  We had once set up a pilot for a small converted Converter a series (or parallel, cant he recall) cable to the usb port
  (I have already uninstalled the drivers but nothing has changed)

  It's just a guess...

  any idea on how to solve this little problem? : p

  Hello

  You said external USB HDD appears as an unknown device on two of the three USB ports.
  What appears if you connect the HARD drive to the USB port on third?
  It appears as an unknown device or what?

  The device usually appears as an unknown device in device because manager not installed device drivers.
  I check the HARD disk for the drivers and try to install it again.

• Two of the three USB ports works only on Compaq CQ71 (Windows 7).

  Hi, I have a Compaq Presario CQ71.

  There is a USB port on the left and two on the right. The one on the left works but the two on the right are not.  An "unrecognized" message when you use one of them, but not with each other, however there is power coming from him, as when I plug a mouse to infrared light is turned on.
  Ive updated Chipset drivers and BIOS on Compaq website. I also made sure to do all the updates of Windows. Help, please! Its driving me crazy!

  Did you meet a very old thread... but... I know that with some machines, you can actually disable some ports USB in the BIOS. Take a look here and see if there's anything out there.

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

  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.

• USB key into the USB port does not appear in 'my computer '.

  Original title:-drive Flash USB port does not appear

  I have laptop Dell A 4 years and cannot use USB ports. My data flash drive lights flash but nothing shows up in 'MY Computer'

  It turns out that there is a problem connecting to the motherboard... so it ' s not worth repair. However, I believe that I can connect to the Internet by the yellow cable supplied with the router. There is also a card I can buy known as PCMIA card that will give me 2 additional USB ports. It's cheap enough to give it a try.
  Once more a big thank you to all those who have offered their advice on this matter. I'm amazed that so many people are willing to give of their time to help a novice

• NB200-12N - USB port does not work

  Hello

  I updgrade my OS from windows 7 starter edition to now a windows 7 home basic 32-bit usb port does not work is the (only) in the left near card reader sd and lan.
  Can you please hellp me to install it? I have download the drivers from Toshiba for my NB200
  But does not work.

  Thank you

  Paulo

  If everything is OK and right drivers all USB ports should work. You cannot install the drivers for each port separately and force one of them to work properly. On this machine, all three ports are the same USB2.0 ports.

  Try reinstalling the chipset utility.

  By the way: two other ports work well, right?

  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

• El Capitan USB port does not worked well under Yosemite.

  Running a VMWARE image of the Linux kernel using a Sentinel of SafeNet USB license dongle canned.
  Has worked perfectly under Yosemite unfortunately too long to go back.

  The USB port does not work with other USB devices?

  I suspect an incompatibility with the EC and the sine of dongle USB EL strengthened using third kexts. They must be signed, and so a softer update for the dongle is probably necessary.

  The difference is that the ports on the left are integrated on the motherboard, rights USBports are a card with a cable that can be replaced in case of failure.

  If you have a distribution of Linux (Ubuntu, Mint...)  You can use it in live mode (without installation) to test the USB ports

For some reason, some usb ports do not work on my computer.  The model I have is a HP m9077c with the Windows Vista 32-bit operating system.  the m9077c model has usb ports, four in the back and two up front. The four in the back work well, but the two front won't work.  There are also three other usb ports on my monitor, HP w2408, but these do not work either. What makes really fiddly to use all the material that I currently use on it. Can anyone help? Thanks for your time.

• Before the USB Ports does not. Dell Optiplex 390

  Hello

  I recently bought a used optiplex 390, I did a fresh install of windows 7.

  The front USB ports refuse to work (the back ones that work very well)

  I tried upgrading the BIOS, then the chipset, but still no luck.

  Any ideas?

  Set to refuse to work.  The front ports allow only 100ma of power for keyboards and mice. Need power 500ma USB flash drives.

  Façade cable may be broken or the ports themselves perhaps.

  HOWEVER, this model and many other dells can disable various ports in the bios.

  I have a problem with my laptop [HP 15-r002se] all three 3 usb ports do not work, or even detect that something is plugged, I tried techniques to conquer the problem by the system of formatting and reinstalling windows 8 32-bit where I found myself without success, because I can't able to get compatible drivers of troubleshooting. Then I go to the usb ports even on windows 7 64 bit does not. and finally, format and install windows 10 64-bit, I downloaded the drivers from hp website, but unfortunately when I run the downloaded software sometimes nothing appears either to the pop-up a message on the error or continuation and sometimes it shows this kind of error after it finished extracting

  

  Finally with the help of pilots pack that I managed to install all required drivers but finally arrived with NO SUCCESS, yet neither the operation of the usb port. Here is the screenshot of my device manager.

  

  Please, I seriously need your help to solve this problem, because I am a student, I can afford to buy another laptop earlier

  Hi @Mustapha_Musa,

  I read your message and please try the following steps. A brilliant work has been done by trying these steps. Kudos to you on this point. It's a problem of clear material with the device. The USB ports are defective, the motherboard should be replaced. you will need to contact HP telephone support on this subject for the machine.

  HP technical support are available by clicking on the following link:
  
  http://h22207.www2.HP.com/us-en/?openCLC=true
  
  (1) once the page opens, please select the country in which you are located. Then enter your model of HP on the right number.
  
  (2) then choose "Contact the Support" tab at the top and scroll to the bottom of the page "HP Support - contact" to fill out the form with your details.
  
  (3) Once finished, click the "Show Options" at the bottom right.
  
  (4) Finally, scroll to the bottom of the page and select "Get a phone number." A file number and telephone number will now fill for you.

  The workaround, for now, is the following: If you have a USB port on the device that works, then you could buy a USB port extender and connect it to the port good work.

  Then you connect other devices to the USB port extender. This way multiple devices may still be connected to the computer.

  Just to say thank youPlease click the ' Thumbs Up 'button to appreciate my efforts. If it helps, Please mark this "accepted Solution".

  Thank you and have a great week ahead.
