Is it possible to use a divice like a Belkin FireWire 6-Port Hub and not run into any CPU consumption issues or slow downs? My concern is that I am recording with Pro Tools LE 8 on a MB403LL/A (2.4Ghz 13.3" early '08) and I have a FW external HD OWC 320 7200rpm and I NEED to use it. I also have a USB interface that allegedly consumes much CPU and would be better if ran via FW. BUT! I only have 1 FW port.... Any and all help is appreciated guys. thanks!
