do i need one more carnetix attached the same way as the first in a different mobo usb port for thw two 4-port usb hubs solution?
if i use the 8-port solution does carnetix provide enough power to the 8-port hub? (500mA x 8 = 4A, i think carnetix provide just 3A max, right?..)
Yes, it should work for other systems, but there are easier ways if you access to the power supply and extra power, just power the hub directly from the 5 volt rail of the power supply and your done. You can't access this on the G4, so you need an external power supply.
The carnetix has a max of 4 amps which means if you hook up 8 devices that draw the max of .5 amps for each usb device, you will need a bigger power supply. If you have alot of devices that don't draw that much power, your not going to max out the 3 amps. Better yet, you should just add 2 4 port hubs, power 1 for your high power USB devices and use the other for the lower power devices that can just use bus power and you won't have to worry if your overloading the power supply.
