Hello guys! A month ago i burnt out my macbook pro´s firewire port when i connected it to an external hdd. I guess this was caused by a bad firewire cable. I will of course send the computer for repair but now i have to to finish my video project and really need a working firewire port. Yesterday i purchased a Belkin F5U506 expresscard/34 with 1 usd & 2 firewireports http://catalog.belkin.com/IWCatProductPage.process?Product_Id=278321. The expresscard´s usb port works fine but the firewire ports are not working :S. I connected both my external hdd and miniDV camcorder to the expresscard and they are not recognised by the macbook pro. I think its a bit weird that the usb port is working while 2 firewire ports not. Do you have any suggestions? Has somebody tried this expresscard on macs?
