  What about the USB port State in Device Manager?
  Are there any yellow exclamation marks?
  If you would find any yellow exclamation point in device manager then this would mean that the work of t unit doesn't properly due to a software/hardware problem.
  In most cases, it could be a software problem (driver is not installed correctly, etc.)

  I recommend you this short work around:
  -First disconnect all USB devices
  -go to the Device Manager and remove all USB hubs and USB controllers in device list
  -Close all windows, and then restart the laptop
  -wait until the OS (operating system) is initialized and installed the USB ports.
  -connect a USB device and test

  Good luck

• Qosmio G does not recognize the mouse using two left USB ports

  I'm right handed so I naturally put my optical mouse Saitec in the port of the right hand.

  The other day I plugged it in the ports of the two left hand and the machine did not recognize the mouse.
  He went through the process of installing the drivers (even if it was done a few weeks ago, when I plugged in the port of the right hand)

  In any case the mouse doesn't at all plugged into ports on the left side.

  Does anyone have any ideas as to why what is happening?
  Look of Sean.

  Hello

  Have you tested the two left with other USB devices USB ports. That is to say USB flash stick?
  Maybe you should do this to see if it could be a defective USP port.

  But I recommend to test this;
  First disconnect all USB devices
  Then go into the Device Manager and all the USB host controller and hubs USB remove from the list of devices.
  Close all windows and restart the laptop.

  Finally the operating system should recognize the new devices (USB ports) again.
  Connect a USB device to one of the ports on the left and check if it would work.

  Good bye

  PS: What Qosmio do you have?

• Satellite Pro L10 - USB port will not recognize devices

  Hello

  I got a L10 for 18 months. Under the guarantee, I got a replacement motherboard mounted. Everything has been ok so far. A USB port will not recognize devices, a port is ok, but randomly turns off a device attached to it and comes up with the message "USB device not recognized". The third port is ok all the time.

  Any solutions or suggestions?

  I guess there is not enough power on the USB ports and external devices may not work correctly. It is not easy to say why this happens, but there may be a problem of welding.

  I recommend you contact the service again as soon as possible.

• Satellite P10-304: USB Ports not recognize anything

  I have a Satellite P10-304 and the USB ports not recognize anything that are attached to them. Device Manager tells me that they are enbaled and works correctly. What can be wrong with them or what can I do?

  Hello

  One of my friends has the same unit on the work and everything works perfectly. It uses the USB hub too and have many external devices connected to the unit.

  By the way: something like who can occur if the external device is not removed correctly use safely remove hardware option. If you try to connect any other device after that in most cases it is not recognized at all. In this case, you can restart the device or remove ports from the Device Manager and use the hardware detection to find them again.

  Good bye

  Original title: problems with USB ports

  Hi Alba.

  1. who is the operating system installed on the computer?

  2. What is the brand and model of the computer?

  This issue may be caused if one of the following situations arises:

  • The currently loaded USB driver has become corrupt or unstable
  • Your PC requires an update for problems that could conflict with an external hard drive USB and Windows
  • Windows may be missing other problems hardware or software updates
  • Your USB controllers may have become corrupt or unstable
  • External drive can enter selective suspend
  • Your PC motherboard may need updated drivers

  I suggest to connect the USB device to a different USB port and check.

  You can run the Fixit provided in the article and the Coachman.

• USB ports not recognize flash drives

  I was just given a Gateway Performance 550 windows 98-based computer. It is plug-and-play, have two USB ports. Printer and scanner included work on plug-and-play. The computer will not see even a device plugged in when you insert a flash drive. Should readers flash works with Windows 98, or should I switch to XP for the software to recognize? I read that some parts used USB 1 format and taking the computer earlier. It is supposed to be dimensionally identical to the USB 2, but run a little slow, but always interchangeable. Maybe the USB 2 flash drives are not interchangeable.

  I'm not the best expert on all this, but I don't think that Flash drives were even invented where 98 was around.

  The 98 machine would not have the drivers for a Flash drive.

  You can visit the web site of the manufacturer of the USB and see if there are 98 compatible drivers there.
