My computer only came with USB 1.1 connections, so I installed a Belkin 5 port USB 2.0 card in an available PCI slot. My cable modem and webcam run through it just fine. I have am AVerMedia EZMaker 2.0 video capture device that I want to use to transfer my analog camcorder videos to the computer but the computer always locks up after a few minutes of use, sometimes a few seconds. I have to unplug the device and reboot the computer and everything's back to normal. What setting am I missing to keep the computer from locking up?
