Why does my firewire card have a socket for a power connector?
I never really thought about it before. It's an old internal USB 2.0 and firewire card, and it has a socket for the old type of power connectors. But it always worked okay without plugging anything into that. Is it only for a different type of slot that doesn't provide power?
Also, plugging something in to the USB ports on it, causes the message to pop up...the one about how the device could perform faster if you plugged it in to a USB 2.0 socket. Huh? It IS USB 2.0. The card has been in several PC's over the last 10 years or so and I always got that message on certain devices. The first motherboard it was on only supported USB 1.0, but the rest have been 2.0 or 3.0. I'm starting to think that I should plug some power into it, though I really don't see why that should make a difference. Plus, I don't want to risk damaging it as I still have a few cameras with DV output.

Do NOT plug power into it, that is probably a VERY low power 5v OUTPUT Some early equipment required power in excess of the standard 2 a maximum of the USB ports. If it IS truly USB 2 it probably would NOT have worked on a machine with only USB 1 support.

Perhaps for devices that need the extra power, but as for that message, sometimes that comes up when a device doesn't properly connect to the socket, or negotiate with the USB chipset, I wouldn't worry about it.
However, I would not plug anything into that socket. You could fry the card. If you want to find out what it's for, find the spec sheet for that one.
