USB 2.0 or 3.0?: My computers ports are 2.0 and the drive came with both 3.0 and 2.0 cords but only the 3.0 connection actually had the computer register a new BD drive. the 2.0 did not work.
I’ve looked up the manual for your model–just to make absolutely sure–and there’s not supposed to be two USB cords included, are you talking about one cord with two USB connectors on the end? Assuming that probability, when you’re running a drive like this over just USB 2.0, the second connector is for additional power (not a choice between USB versions), which a USB3.0 port would otherwise be able to supply through a single connector. With your setup, you should be plugging in both USB connectors so you have enough power. Try it again this way.
Also, Nero hasn’t been good in a long time, I’d advise against bothering with that at this point.
