  You have the latest firmware on the SSD?

  Have you installed all the drivers and software listed on the site Web of Toshiba? Make sure that you install the Intel Chipset utility first, followed by second PVAT.

  Also make sure you have Win7 SP1 before you install the drivers and update the BIOS to the latest revision.

  If you still can't make it work, you can order the Toshiba recovery disks and install the original image on the SSD, so everything works correctly.

• C75-A-12 satellite - after Win8.1 update, 2 ports USB + cam does not

  I bought my computer in the MediaMarkt in Holland about 6 months ago.
  After updating Windows 8.1 don't work the USB 3.0 and USB 2.0 port on the right side of the computer.

  As my webcam, this one does not work too.

  I tried to install drivers, uninstall and restart, I tried Windows 7 installing the driver in compatibility mode... nothing works... I bought a Toshiba since I thought is was a reliable brand...

  Don't think,.

  What other van I do?

  It seems that Satellite C75-A-12D PSCE2E 04804UGR was already pre-installed with the 64-bit Windows 8.1 System.

  I would recommend you to get the system to point in time early (before the MS updates was installed). In case this isn't possible, use the Toshiba HDD retrieve and set the operating system to factory settings.

  Then make sure that the webcam, but also two USB ports.
  In case everything would work properly, perform the updates of the system of Ms.

• 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?

  Post edited by: caddy

  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.
