I need Dell Studio 1557 webcam driver.i can not find this driver in Dell Drivers and Downloads page.
Have you tried searching Windows update for the driver? I've never seen Windows 7 fail to install a webcam out of the box.
I found the install files from the CD, and can't seem to find a driver at all, which to me says it's assumed the system will take care of it.
Does it show up in the device manager?
