So I have an older DDR3 motherboard and a Sony firewire webcam and I need to sell it. The problem is most users out there are using newer laptops, none of which have firewire. I saw there are many firewire to USB adapters available. On Ebay they start at about 2 bucks. Is this all I need? I thought I might be better to get one that works with USB 3.1 though. The firewire speed of the webcam is 400 (the slowest) so it should be easy to connect. Or is there a better way to use this with a non-firewire machine? Of course for a desktop computer one could just get a PCI or PCI-Ex1 firewire card. Would that be a much better way to do if one was using a desktop computer?
