Well i thought about using a card with plug for external power adapter and then draining the power from a USB port (or in worst case a battery) but i think that the USB has only 5V supply and i will need more for firewire right? The UltraLite comes with a 9V supply for standalone operation so i think this must be minimum. I?m not sure about the specs of firewire because everywhere i look it says that it can operate up to 40V. What the hell does "up to 40V" mean? That it will automaticly regulate the voltage for what gear that is used (sounds unusual)? Well anyway i got my new laptop yesterday (yeah )and i ordered the MOTU UltraLite 2 days ago that should arive soon so i can begin experimenting...'

Edit: Just got a mail from Aten (a manufacturer of firewire cardbus cards). They say that the ports ARE powered BUT it depends on if the computer can (or will) deliver enough power. If it can, i can use it and if it can?t i will need an external powersource. Maybe good news
