My advice would be to first

download the latest driver pack, making sure to obtain the chipset drivers.
Uninstall the USB ports
install the chipset drivers (and other updates that may be needed).

Some devises are quite choosey.

First thing to try is this: Go into the bios. When the computer boots press the "F2" or "DEL" key on your keyboard, you will now see a blue background with white text or a black background with white text, carefully search for the "USB" section and make sure in the usb section the "Legacy" part is "Enabled", and everything usb is on "Enable". When done click on "save and exit", this will reboot your computer and hopefully your usb devises will work. If not then the list below might help.
Get a tool/program that will clear your temp files, something like:
This will flush your computer and hopefully get the devises working. You could try and update your motherboard drivers if possible the bios also.

Please post back if you have any more problems or questions.

USB hub not working on Toshiba Satellite A135-S2276 windows vista

by shey_fav062001 In reply to Some devises are quite ch ...

I tried what you suggested by going into the bios. I was not able to get into the bios as it was asking for password and the password i supplied which is the one i use to gain access into my laptop did not work. I did not password the bios when i started using the laptop so i don't know what to do next. Will appreciate any further assistance.

Then if you did not put a password into the bios..

You will not be able use any of the usb ports (period). The password is not located in the bios but on a security chip, and if you do not know the password then you will have no access to the bios. So the best place is to ask the person who sold you the computer or go to Toshiba and ask them to put in a new security chip. :)

Please post back if you have any more problems or questions.
