Hi folks, My rMBP is coming in soon and I was wondering if anyone has purchased a USB Blu-Ray for theirs. All of the bus-powered modes I can find have two USB plugs (one for data, one for power ... allegedly). On the rMBP, there aren't two USB ports next to each other -- instead, the two ports are on opposite sides of the computer. Now, most of the BR drives *should* be able to run off just one USB plug, but I was wondering if anyone can confirm success with this. If you've gotten one to work with just one plug, which model? I've been looking at these: Samsung: http://www.amazon.com/Samsung-SE-50.../B006B7R9QE/ref=sr_1_1?ie=UTF8&qid=1345087675 LG: http://www.amazon.com/LG-Portable-B.../B006X2HD2M/ref=sr_1_1?ie=UTF8&qid=1345087772 OWC: http://eshop.macsales.com/item/OWC/MRSSBD6X/ Any thoughts?
