Hi guys I'm looking forward to buying a cheap Edifier 2.0 Speakers that i'll be using it temporarily. The speakers are USB powered. Now i've read at lowendmac.com and it said that Is this true? The USB power part? I have the 7,1 MBP. I'll also be buying a Targus USB hub for mac. So if the above is true, i have to plug in my usb hub to the port closer to the front to be able to power the speakers to full power? Thanks in advance!
