I've been having some problems with a NEC USB 2.0 card I recently purchased. I have two things hooked up to it. One is a Dazzle DVC-150 which uses 2.0 and a scanner which is only USB 1.1 Whenever I shut off the computer, then start it...it "loses" the driver for the DVC. I figure the 2.0 card needs an update, but I can't find one....any ideas?
