USB hubs and arcade controls
epetti:
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.
