From where can I get a usb video driver for my canon video camera?

If you are looking for updated drivers to transfer mini DV tape based video from your camcorder using USB,you won't find those. You need to stopusing USB and install a fire wire card in your computer unless you already havea fire wire port installed and transfer using the camcorder's DV port with a Firewire, i.Link - all the same thing cable. USB won't work. For editing video, the camcorder needs to bein Play mode and Movie Maker will "Capture" the video and import itto your computer over the fire wire connection. And last it is easilydownloadable from net and it comes for trial version and for full version youhave o pay some money.
