I have recently purchased the dm4800 and the firewire card, along with a brand new hp pc. I have the tascam companion working fine through my pc, and have the firewire card hooked up but on the status the card reads ok but the 1394 says no cable it will sometimes pop up and say locked for a second then go back to no cable i have downloaded all the drivers necessary for windows 7 and tried slot1 first now ive trried slot 3 and says the same thing i ALso moved my firewire ports in my cpu to another outlet and still the same thing. i am trying to open my commercial facility, but this is my only hold up. Someone PLEASE HALP!!!!
