USB hubs and arcade controls

Interesting. Didn't realize there was a difference between the ports on the back of the computer and those on the front.

Thanks for all the tips.

PL1:

The difference isn't necessarily front/back.

If you use a non-powered hub, each port is rated for 100 mA

If you plug into a USB connector on the motherboard, those are rated for 500 mA.

If you use a USB plug on the front of your system, it might be a direct connection to a USB header on the motherboard (500mA) or it might run through a non-powered hub to allow a card reader and USB ports.   :dunno

On an average PC, there are two, maybe three physical ports.  Each port is specc'ed for 500ma of current.  These ports are then divided up to provide 4-6 USB connections.   So splitting the current draw between a couple of physical ports, can often take care of issues where there is not enough available current.
