USB til firewire?

Hvad med et PCcard eller Expresscard syntes ikke jeg kunne finde noget med USB.

Det er måske slet ikke muligt med Firewire til USB

FireWire, uses a "Peer-to-Peer" architecture in which the peripherals are intelligent and can negotiate bus conflicts to determine which device can best control a data transfer
 

Hi-Speed USB 2.0 uses a "Master-Slave" architecture in which the computer handles all arbitration functions and dictates data flow to, from and between the attached peripherals (adding additional system overhead and resulting in slower data flow control)

Der er ikke PCI-port i PC'en

Så kan det nok blive svært :(

ja:(
