Is it possible to power an USB Hub from the computer's PSU?
Edit: I have tried to hook the hub directly to a 5V line from the psu (floppy connector), the computer won't boot and the dvd and hd lights keep flashing. I got a male molex connector from a broken floppy drive and found a plug that fits on the hub's power input. I checked for short circuits and correct polarization.
When I plug the hub (just the hub, nothing else on it), the computer won't boot. When I unplug the hub, it boots as usual.
