i have a toshiba satelite t135-s1312, the operating system is window 7. Im having some problem with the drivers on my computer. WHenever i start up my computer all of the usb host controller DRIVER stop working. i tried to uninstall them and restart my computer. they start working again, but the same thing KEEP happening again when i restart or start up my computer. Please someone help me. i DONT know much about computer. Thank you!!!Is this computer still under warranty?Many here want to help you. Please include important details. The Laptop you have was sold with Windows 7 64 bit installed. Is that right?
What happened before the USB stopped working? Is the Toshiba laptop still under warranty? What USB devices do you use? Camera? Printer? These must be installed with the 64 bit versions.

Please let us know if indeed, you are using a 64 bit version and have installed drivers for printers or cameras or or similar devices.He never stated it was 64bit...Thank you guy for the concern. Mine is window 7 ultimate N-64 bit. I dont think it is still under warranty because i bought it online. i have a printer. Nothing happened before the USB stop working. I started my computer and tried to plug in my iphone or my flash drive. The computer didnt recognize them. so i went to device manager to check and saw they stopped working. I uninstalled them and restart my computer, the computer reinstalled them automaticlly, but it happened again whenever i shut down my computer or restart it.
Ps/ the driver for the computer's webcam couldnt be installed. Looking forward for your replies. Thank You! Quote from: Geek-9pm on January 31, 2011, 11:24:36 PM

I dont think it is still under warranty because i bought it online.

Do you mean upon first loading of your system? Before inserting any devices(not recognized), look in your Device manager, are there any red/yellow marks sited?

Even hardware bought online has a warranty, when did you buy it?

Toshiba has some of the best warranty support available.  I would first try with them as this may be a common issue for them.  I'm just thinking that if it is still under warranty then you might as well get what you paid for.

With Windows 7 ^$ bit ALL drivers must be 64 bit.
Whenever you install anything that plugs into the USB port there is the possibility of wrong installation. (Windows 7 automatically installs the right drivers. But if you over ride Windows 7 and force the install of wrong drives, it is wrong.) The wrong driver will crash of hang the system  Or not even show a problem until later. The drivers from Toshiba, the original ones, are the correct ones. Other devices, printer, cell Phone and Web cam would have the wrong drivers. Unless it explicitly says 64 bit.
