That would be USB 2, which is marginally faster than FireWire.

On a video camera, the USB port is usually used primarily for
downloading still images (usually stored on an SD card) just like an
ordinary stills camera, this doesn't have to worry about the portion of
tape with the data passing by the read heads (be it magnetic for DV cams
or optical for DVD cams) before transport protocol has had time to
tranfer it to the camera.
The problem is that most camcorders will only have a USB 1.1 (or USB 1,
which is even slower) port, which is considerably slower than FireWire.
