Hello everyone, I hope your having a good day.. :thumbsup:

Okay So I am stomped on a Toshiba Sattallite A135 laptop, with W-Vista O.S.

Any external usb device such as flash-drive or even mouse is not recocnized.

What I did:

1)Ran Anti-malware
2)Checked it in SafeMode
3)Upgraded W-Vista to Service Pack-1
4)Messed with Device Manager
5)Downloaded M.B. Drivers and Intel Usb Drivers

After all of this I am pointing my finger at the O.S. it self. The Usb device work it tells me its in there but its not recognized (the device).

I will run a "Repair" with OEM Cd's see what happens.

Any Suggestions?? :huh:

Have you spritzed the USB ports out with a little compressed air yet?
In the beginning there was the command line.

I always have one solution for USB port problems...uninstall the USB controllers (hubs, too, if you like) in Device Manager...and then reboot the system, reinstalling same.

If that doesn't work, I go to my ace-in-the-hole...a PCI USB 2.0 card :thumbsup:.

Thanks guys for the suggestions.. :huh:

I have not cleaned the usb ports with compressed air, but I will do that.

Unfortanetly I can not put a usb card in this because it is a laptop.

What is weird is that it sees the usb device sometimes. And other times it says Device not recognized.

In safe mode it sees the usb drive however it does not display the content of the flash drive.

The Drivers are the ICH7 family from Intel. I tried reinstalling them with out success. :huh:

Thank-you :thumbsup:

if it works sometimes and not others i would say it is a connection issue. if cleaning does not work it could be the connection to the motherboard.
USB can be added to a laptop if you have an express card slot or equivalent.
