In my setup, I plan on having a 4-port USB hub connected to my carPC in the trunk via an active extension cable. I've done a lot of looking around and see some powered hubs (with separate adaptor and wire) and some without. In my front 4-port hub i would hook up accessories like a keyboard, mouse, PS2 controller converter (for emulation)....and simple stuff like that. SHould I worry about getting a powered hub? What USB devices NEED a powered hub to function?? webcam? Just curious, because at the same time, I dont want my devices to go dead if i hook up stuff into all 4 ports on the front hub at the same time.
