  3. Do active USB hubs cause latiency / lower quality in the things using it?

I've got a gamepad, headphones, standing microphone, webcam, and two mice, needing a total of 6 USB ports, and my tower only has 4. So I'm going to buy an active USB hub. But will that cause a drop in quality if my gamepad or mic uses it?

Just make sure it's powered, probably what you mean by active, and it shouldn't have any issues.

Yeah, I meant powered. Thanks. I was just questioning how one socket would deal with all the extra data but I guess it's not an issue?

Naw, one port is rated for an absurd amount of devices I believe.

Why 2 mice? Just curious.

Unless you had a couple of external hard drives, I don't think you'll have any problems.

the latency is probably under a 1000th of a second.

To clarify, the amount of devices is irrelevant.

The amount of data, however, is not. Don't count on things like flash drives or external hard drives to function at full speed if they're plugged into a hub with several other devices passing data to the USB port as well.

A USB 2.0 port is rated at up to 480MBps, but doesn't really reach those speeds in real world use. In addition, USB 2.0 is only half-duplex, meaning it can only send or receive data. It can't do both at the same time, like 3.0. I'm not sure how a hub will come into play in a half-duplex situation.

Short answer: Input devices won't have any noticeable issues. Devices that do a significant amount of data transfer are better plugged directly into a port.

http://en.wikipedia.org/wiki/USB

Up to 127 devices, including hub devices if present, may be connected to a single host controller.


and, no, of course you won't get full performance from all devices connected like that, but it's possilbe.

One is a standard pointing mouse, the other is a 6 DoF 3D mouse for manipulating the camera in 3D modeling. (It's a 3DConnexion SpaceNavigator) it's a life saver.
