Need the full model number from the bottom of the laptop, it'll be something like "L300-EZ1525"
From there you can go to the toshiba website and look for the camera drivers.
Go to:
http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/home.jspClick the blue Download link
Select Laptop in the left category,
Select Satellite Pro in the next category,
Select L300-XXXXXXX replacing the X's with your specific model,
Then hit go.
On the next page you get a long list of downloads, click on the drop down that says "All Categories" and select "Driver".
The list is updated with drivers only, look for anything that says Camera, if there are any you may notice it says Windows 7, click that and download that and you should be good to go. Otherwise you can try the one for Windows Vista, if that doesn't work, you'll have to contact Toshiba support by email or phone and see if they have a solution.
